Thank you Doc. I have a 22 RGS & 2 times my dash showed no pressure in the front tire. I noticed when tires got hot on long rides sometimes it goes out. I checked when it came back on it showed 42psi. Now after watching this video im going to double check with a gauge not the system.
I have a 2015 Road Glide CVO which didn’t come with tire pressure monitor. I’ve found some thing much better for those of us that want to have a tire pressure monitoring system. It’s called “FOBO”. For about $100 You get two tire pressure monitors, one for each wheel. They replace the tire valve caps. Best used with metal valve stems instead of the OEM rubber ones, my bike came with the OEM metal tire valve stems. Now the cool part, FOBO syncs with a FOBO app on your smartphone. You can read your tire pressure from about 32’ away (Bluetooth). Comes in handy if it’s raining outside and you’re still in your hotel room. FOBO has given me twice an alarm that I’ve picked up a puncture and in which tire. It also monitors interior tire temperature. FOBO is user friendly and can be adjusted to your tire pressure preferences. I have had these on my CVO for over 100K miles. I have no vested interest in FOBO.
My 2016 Limited tpms is always dead accurate when compared to a gauge reading. While i don't rely on it 100%, it's a neat feature. I picked up a nail 50 miles from home and used it to watch rate of leak. I was also surprised how much tire pressure increases while riding.
My selling dealer has told me there is a H-D Service Bulletin that states not to run nitrogen in the tires on my '18 CVO Limited SE 115 Anniversary "because the nitrogen will ruin the sensors". Now the air we breathe is 78% nitrogen. How can the 100% nitrogen ruin the sensors? And, without using a vacuum pump and totally collapsing the tire before replacing the air with nitrogen it seems to me that the most concentration you could get in a tire is about 95%. Your video was very informative. Also, my rear tire may show 40 psi pressure when first started on a warm day and riding 2 up on Texas highways I have seen it reach 50 psi pressure. After it reads 50 psi the next measurement will be dashed lines, no numbers. I have never seen 52 psi.
Awesome, the absolute best description for temperatures verses pressure that I've seen, always an argument but I've always gone with 10° = 1 PSI and now I can show my friends - hey doc Harley even says the same thing. Thanks as always.
Some guy posted his 19 RGS and his works. He just added 32700096 sensors and had GTS flashed to enable TPMS then turned on sensors and it worked. Today I bought the same sensors and in the process of changing out my stock wheels with CVO Aggressors. The big thing is the sensors are 8.3mm so the wheel's needs to match the stem hole size in my case the Aggressors do match, otherwise FOHO sells an adapter to reduce your 11.3mm hole if that be your hole size. My thought is both our Infotainments match along with the BCM's and my bike is essentially the same being it's an 18 RGS. I'll give it a go and update. The 18 FLTRXSE uses the same sensors and BCM which also accepts the same 834A Infotainment upgrade and I checked with the local Harley Tech who gave it a thumbs up. I'll update in a month or less.
@@LowCountryHarleyDavidson Doc would you please let me know if there is a certain direction the sensor has to be placed along with toeque setting? Outside of looking at an actual CVO manual I could find no info out there. One end of the sensor is rounded and the other end is squared, so does the rounded end have to be pointed in the direction of rotation? I'm planning on facing the stem to the right and took pictures of the information on the sensors before I install them for the technician's benefit. note: I bought a 2018 FLTRXSE Supplement Manual which shows 54-62 inlbs and to not let the sensor touch the wheel while tightening I assume so not to cause damage to sensors and to face stem to right.

Hey Doc, so I have a 2020 SGS with RDRS, and I installed a Sony Ax7000 head unit and a new front tire setup and had the TPM installed for that type of wheel and tire. My local harley shot is telling me that they can't link the new TPM to my motorcycle, because I changed out the head unit. I still have TPMS working in my rear tire, through my speedometer. Their telling my that I can't even have the reading displayed under my speedometer because I changed my head unit. To me it sounds like a croc of shit. Please HELP!!! PLEASE TELL ME THE TRUTH...

Hi Doc, thanks for sharing your knowledge. I recently had my Boom Box GTS radio replaced under warranty on a 2021 Street Glide Special (GPS issues), the new Boom Box GTS works great but I found that the TPMS display icon has disappeared from the Boom Box display. However, TPMS is working on the odometer display. Can you help me with a recommendation?
There have been several software updates. I believe you can go to HDSoftware internet site look up the latest edition number and compare yours. It is possible a rookie tech installed with Factory original software and did not update….Doc
@@LowCountryHarleyDavidson Thanks a lot, Doc: My BB GTS software version is M23.22.27.00; this is the latest versión, I think. What else can I do? Thanks!!
Good info and presentation. Two words come to my mind, “Over Engineered”. Why can’t they build something that doesn’t care if it’s reading air or nitrogen? The stick or dial gauge doesn’t care what gasses it’s reading. Always amazing how complex thing have to be.
The H-D sensors are built for air and not nitrogen. To my understanding new components/materials have to be added to the TPMS (with added cost) to use nitrogen in tires. Not all areas/dealerships have nitrogen.
Yes they can go out. Whole unit replacement…..Sometimes the signal gets lost. I would first request a dealer to reactivate both sensors before replacement. Side note: these sensors can be damaged in tire replacement if. It careful….Doc
I have an Harley Davidson CVO 2017 Ultra Limited My rear tire sensor is still reading high as the tire heats up. I check the tire cold to match what the bike is showing, and it's 2 to 3 psi off. Example: If the tire is cold, it reads somewhere of 37 psi abs as I ride it goes up to 42 psi and as I increase the speed above 80 it reads between 44 to 48 psi. When I stop, it decreases down by 2 to 3 psi Any Suggestions
First the TPMS was and is never accurate. I believe it was ment to help you see a drastic change ie a nail leaking. In your owners manual there is an equation for psi adjustment due to outside temperature. Your post reflects the equation results. We learned in high school science class that heat has a direct effect on air pressure in a closed system. The friction of the tire on the road creates heat which in turns increases tire pressure. My suggestion is to enjoy the ride….Doc
Thanks for the video! Can I order and install a set of 2020 HD Tire Pressure Monitoring System valves for my 2019 RG special? and then update my settings on my bikes computer to use these? My dealer / service tech says I can? But doesn't seem like it to me... Ide like to just even have then 90 degree valve stems. Its a PAIN in the A$$ to check and fill on this bike.. Thanks
No, you can not add TPS and update software. Software is only available from factory when made for the model.....Noted it IS a pain to check air....Doc
I had 37psi in my front 40psi then tried 42psi in rear tire (cold) prior to riding my 2020 street glide. It was 82° out. Wife on back, our leathers in bags, im 190lb shes 125lbs. My tpms was reading (HI TIRE PRESSURE) in rear. Why? Not over weighted or over inflated. Back sat in garage for a week. I check psi prior to any riding.
Thank you for the comprehensive detail you put in to your videos. I have a question closely related to this topic. I own a 2020 ultra classic. I recently made some changes, specifically, I change the front tire to a fat tire. In this video you mentioned that the sensor is calibrated and not interchangeable. As a result, I get a low tire pressure notice on my display, FR26 appears on the odometer display and finally, both tire icons remain lit in the MPH and RPM display. Is there a fix or bypass to correct these issues?
Since this video, HD has commonized the sensors. but I believe the internal Software for the Vehicle (it knows what model and tires this bike should have) will get in the way of modifications. If you are willing I believe the TPS can be shut off so the indicators won't be in your display...Doc
I can't wait to HD has a occupant sensor install so the air bags don't deploy accidentally. The wheel sensors are a great thing....I needed one the other day when I was riding I felt a thump thump as I was cruising.. ..lol
I understand changing ABS wheel bearings when changing wheel size but i don't understand how the tire pressure sensor would be affected by wheel size. I have changed wheel size front and back on a CVO and the system seemed unaffected. Mounting the sensors in the new wheels was a issue because of the size and location of the valve stem holes in the aftermarket wheels but the sensors can be mounted to the wheel separate from the valve stem. The stem has nothing to do with the pressure sensor other than it is what is used to mount the sensor to the wheel.
Hi Doc My friend has a CVO2016 Lately the infotainment center has been getting the wrong tire pressure info. Suddenly the pressure goes up, then down (the yellow light for flat tire also shows up). Could this be a bad sensor, or could this be a battery problem in the sensor? According to my dealer there is not much that can be done 😞
The dealer is correct. There is no adjustment and the battery can not be replaced. The sensor itself must be replaced. I would say you got your moneys worth being 7 years old….Doc
@DocHarley , I’m in a hot climate and my rear tire regularly hits that 52 psi where the Tpms reads “HI” instead of a number. Does that mean it’s too high to ride on or just to high for the sensors to read. I’m always worried about that and in the past I’ve stopped and let some air out to bring the hot psi down to say 48. What do you recommend.
First when it comes to tire pressure. Purchasing a top quality air gauge is the first tool to buy. Second as you have done, research the correct tire pressure FACTS. Then set to those figures. You are correct. The pressure sensor has a limit. This does not mean the tire is compromised. As long as the Cold pressure was set correctly the tire will perform correctly…..Doc
Amused that it takes TPMS to finally install angled valve stems. Shame these cannot be used without the TPMS sensors. Approved Angled factory valve stems would be appreciated for those riders that cut their hands on wheel edges when checking tire pressures. IMHO
Yes I have a 2017 straight line engine light keeps going on and off I’m trying to think it is the fasteners they want to charge me $250 at the dealership at Barthels holiday with
Have 2020 cvo and love my toys. I like to use Dyna Beads to balance my tires in past bikes and my vintage bikes. Its not liquid like the "run on" products. Would dyna bead type products be a problem or even just a possible concern with our TPMS ? I
I wish I had known more about this technology before I bought my Harley. I hate the stress and would rather ride than deal with watching my indicators. Im going to sell the bike and get an older model.
I am sorry to hear this. The new technology is supposed to help you enjoy the ride. But if you enjoy the daily tinkering on the Old School stuff enjoy Big Daddy....Doc
Hy Doc! I do have a question for a video (maybe). I have stock 2009 FXSTC with 75000km on it, bought it new and always maintained it myself for lack of alternatives. Almost every time I start the bike, cold or hot, the oil dipstick literally jumps out, flying in the air... It started happening at around 60000km... Am I looking at a pressure problem between engine and oil tank? Or is a gremlin hiding in my bike?! Thanks a lot and a big cheer from northern Italy! - Luca
@Rick Simpson it's the super foolproof softail cap! Just the cap with the dipstick that rests in the oil tank under the seat! I'd revalue all my life choices of I screwed up fitting it! 😂😁😊
Hi Doc, can this system be put on by the dealer ? On a harley that did not come with it from the factory. 2014 CVO limited. Thanks as always great stuff.
Bought a 2022 CVO limited..5 days after delivery, low air pressure warning came on for front tire at 30 psi..filled it back to 36 psi..3 days later, warning came back on and says 29 psi..can I blame that on temp or could it be a slow leak?
Slow leak. You can take it to your dealer for inspection. In the mean time, fill to 36. Make a spray bottle of soapy water, shake and spray all over the tire, rim and valve stem. look for bubbles....(by any chance have you installed custom valve caps?)...Doc
@@LowCountryHarleyDavidson I haven't installed anything on it. Everything on it, came from Harley. I made an appointment at the dealership to have it checked. Thanks for the advice!
Hi Doc, on a 2020 RG with TPMS, if I set correct tire pressure cold when the bike is ridden 5+ miles it's 5-7psi too high. If I set it hot the Tire pressure warning light is on the next morning. Which is correct procedure?
Check cold. Hopefully you are not using the monitor system to fill. Ask a few friends to borrow their tire gauges to make sure your gauge is correct. Are you following the owner’s manual chart for temperatures adjustment to correct psi application? Thanks ~ Doc
My understanding is the sensors last 5 years but my thought is at 4 years have the shop check your battery level. I wonder if there is any tpms monitor that can do that, like maybe on the Infotainment.
If only all YT Vids were as thorough and concise and informative as yours tend to be. Everything we need to know and nothing we don’t. And mercifully without background music! Thanks much.
Hello Doc, I recently purchased a 2017 Street Glide CVO the is equipped with the TPMS, however it is not reading the tire pressure. After watching you video, I removed the seat to find the antenna to changed the battery. I did not locate a device similar to the one in this video. I did locate a clear cylinder shape device about 2.5 to 3 inches long with a red wire at each end of it with the letters TSPEC. Would this be the device?
I have a 2023 Road Glide 3 Trike and it rides terrible. My wife and I weigh 270 together and I would lkie to lower the air pressure to 20 pounds in the rear tires. I have researched that it is suppose to be alright at that pressure. I haven't tried it yet, but I bet it will trip the tire monitoring system. I don't care to look at the warning light all the time, but want to help the ride. Can the monitor be set for a different pressure? What is your suggestion's.
Don’t mess with the tire pressure. It is already too low in my opinion. You are correct, HD suspension is way too stiff for your weights. Look into a better suspension with more adjustability…..Doc
Doc, have a question on tire pressure. I have a '15 Ultra Limited and the manual says 40/36 (rear/front) cold pressure. On really warm days, pressure goes to 46/42 - is there a high side pressure that I need to watch for ? I want to set my aftermarket TPMS high pressure warning accordingly. I ride single only. Thanks - great channel.
I believe the unit will tell u when you have reached the limit of the monitor. The high number is really not that important. It is the under inflated number I watch….Doc
I there a way to reset the monitor without taking it to a dealer. I have about 150 miles on my 2020 road glide and it says I have a low back tire pressure. Checked and it's all good.
Thanks for the presentation. I recently bought a 2020 Road Glide limited and wanted to put in Ride-On in the tire to protect, balance and seal. I've used that product for years on my other bikes. But when I asked the dealership, they said no, not with TPMS. Not that I didn't want to believe them, but they didn't seem sure. You just acknowledge that it was not a good idea. So glad I waited for more confirmation. I appreciate Harley putting out information like this, I have an Indian too, would like to see them do something similar. Happy New Year!
My tire system is going berserk it's not accurate I have 38 in the front tire and low tpm is still lit .it's very annoying . how do you reset the tpm. Also the code will not clear as long as that is lit. Will removing the main fuse reset the TPM or disconnecting the battery?
A tool is used at the dealership. How old is the motorcycle. Sad that the monitors have a non replaceable battery. Like everything else that runs off a battery…things go wrong as the battery gets weak…..Doc
My bike is a 22 road glide special. What I did is I pulled out the main fuse disconnected the battery waited then put everything back hoping to reset the TPM, The TPM showed 33 & 36. I drained the tires down to 22 lbs to see what the reading was ( 1 lb off) then as I put air in I kept checking the pressure to see if it matches my gauge( i tried 3 different gauges) Tpm showed the pressure right away. TPM is a pound under what the gauge shows. Being it was 81 degrees in the garage I set my front at 37 and my rear at 41 . The TPM is showing 36 and 39. I havent rode the bike yet to see exactly what its going to read. Do you know the dealer told mea while ago to overfill the tires!! it yeah right they said the TPM has been a problem but they wont fix it. Typical Harley dealers sell you a bike and don't want to do any work on it.
Doc, out of curiosity, you mention the RF antenna under the seat. Is that incorporated inside the BCM? I've had issues on my 2020RGL with the Red Security/Warning light on, and the Tire pressure indicator blinks and throwing Coo83h, C2000h, and C2001h. This results in the front and rear displays showing - - and no pressure associated. Have had it at my local harley dealer several times over the last year. @Low Country Harley-Davidson Thanks much....
What’s the scoop on tire pressure and heavy riders. Between myself and my wife we are overweight and on longer trips my rear tire pressure goes up quite a bit. What’s the max? Should I compensate by dropping a few PSI? I know the obvious solution is to lose weight but until then…? 😆
Consider going Darkside with an All Season steel belted radial from your local Les Schwab tire dealer. It will easily handle the overloaded situation from riding 2 up with luggage.
Garmin GPS also has a tire air pressure monitor system for motorcycles that don't have a factory system. I have a Garmin 595LM on my 2011 Street Glide with tire monitor front and rear, it seems to work and when or if a tire gets low it talks into my helmet head set.
Great video doc. Not many specific info about Harley’s TPMS, thank you. My question is can we reuse the TPMS sensors from the stock wheel to another Harley OEM wheel? After exchanging the sensors do we need any specific tool to calibrate the sensors?
The odometer needs changing out right? My understanding is odometers with an idiot light are exclusive to CVO's, right? If one has a non CVO bike is subject to Harley's restrictions to only sell CVO parts to a CVO owner.
All good information Doc!! My Problem Brand new 2022 Electra Glide Standard 1200 miles with RDRS system, Front tire reading 248 psi rear reading 369 psi no ECM or BCM or any fault codes low tire icon is off. Pulled 50 amp fuse to I assume reset turned bike back on PSI front and rear were blank after 20 sec ride they were reading the same PSI again? Any ideas? Thanks
I have a video about changing setting from metric to US.. Are you able to do this with your bike? I want to confirm if there is a clitch in the software or transponder....Doc
As always, I could hunt for information all over the web but not find the straight goods and most accurate and concise info until I watch a Doc Harley video. This one answered all my questions and more!
Thanks Doc, great explanation of the system. Props to H-D too for making a system that is smart enough to save battery life. Question: should (can) the battery be replaced at each tyre change?
System seems kind of useless, limited battery life, so when the battery needs to be changed it’s going to cost you at the dealer for the change out, there are plenty of third party TPM’s that the battery is in the cap and you don’t need all the other calibration garbage.
I’m glad I have the TPMS. Started my Street glide the other morning and got a low rear tire pressure warning. 23psi. I looked at the tire and thought no way. I checked the pressure and sure enough. It was way low, so I looked more closely and found a screw in the tire tread. Did a quick plug repair and been fine ever since. Without TPMS I would have ridden off that morning and had a flat tire or worse later that day.
Thanks Doc, really enjoy your videos.. question for you sir.. any way to disable TPMS on 2020 Touring Model. i installed custom rims (stock size's)on my 2020 limited. due to no chrome sensors available and wouldn't mount anyway. i chose not to install.. is there a way to shut off system ,? problem being : cant read miles logged on odometer and constant flashing warning lamp odometer just shows FR 00. thanks for any help. tim.
Great info Doc, I may have missed it in the video but I need a reset. I have CVO 2019, an issue from cold (slightly low 33-34 PSI) on front tire to road temp and low light comes on and stays on. I have tried to inflate to 36 while cold later and light still will not go off. Can I reset some how? Thanks
I love watching Doc Harley - he is extremely knowledgeable. However - this review on the Harley TPMS system left me wondering how to setup thresholds on this system. I had to go to my HD mechanic to ask this - and the reality is - you can't set the TPMS thresholds (low and high) on the *INFOTAINMENT* system console. This can *ONLY* be done via the Digital Assistant. They can set thresholds and then flash the BCM for the new values - which you will not see on your infotainment (high low values, just current tire pressure for front and back). So - this review was a major miss for Doc Harley. He didn't cover this information, which - usually he does and goes into great detail - which is why I watch him.
When the tire lamp comes on at 3 psi while your above 25 mph does the tpms transmit that immediately when the condition happens or does it transmit in the 64 second interval? I noticed a 2019 SGS has a tire lamp when turning on the key. I guess it is not operative?
Doc: you need to explain why the TPS is not accurate with 100% Nitrogen. Isn’t 38 PSI of air the same as 38 PSI of nitrogen as far as tire performance is concerned? The only difference I can think of is that the calculation of how much to increase the cold tire pressure for each 10 degrees of outside temperature would be different with 100% nitrogen. Does the TPS measure temperature?
I have a 2016 FLHXSE. Both (first my rear, tben shortly afterward) TPMS failed. I had wild pressure readings at first then flat lined the rear, shortly afterwards, the front simply flat lined. I haven't had tire pressure features on my bike for almost a year. I keep being told that the sensors are on national backorder with on end in sight. (I have 99,000 miles on her) How long or where can I go to get this repaired?
We all are dealing with part shortage. Your dealer can do a Nationwide search of all dealers. but honestly most dealers are holding on to the parts they have. Until then the old fashion air guage will work...Doc
Thanks for the info. I was hoping I could retrofit my 2016 with the new GTS to have TPMS but you said that it cannot be done. There are aftermarket kits that are mostly in accurate.

Yes they can go out. Whole unit replacement…..Sometimes the signal gets lost. I would first request a dealer to reactivate both sensors before replacement. Side note: these sensors can be damaged in tire replacement if. It careful….Doc
I have an Harley Davidson CVO 2017 Ultra Limited
My rear tire sensor is still reading high as the tire heats up. I check the tire cold to match what the bike is showing, and it's 2 to 3 psi off.
Example: If the tire is cold, it reads somewhere of 37 psi abs as I ride it goes up to 42 psi and as I increase the speed above 80 it reads between 44 to 48 psi. When I stop, it decreases down by 2 to 3 psi
Any Suggestions
First the TPMS was and is never accurate. I believe it was ment to help you see a drastic change ie a nail leaking. In your owners manual there is an equation for psi adjustment due to outside temperature. Your post reflects the equation results. We learned in high school science class that heat has a direct effect on air pressure in a closed system. The friction of the tire on the road creates heat which in turns increases tire pressure. My suggestion is to enjoy the ride….Doc
Thanks for the video! Can I order and install a set of 2020 HD Tire Pressure Monitoring System valves for my 2019 RG special? and then update my settings on my bikes computer to use these? My dealer / service tech says I can? But doesn't seem like it to me... Ide like to just even have then 90 degree valve stems. Its a PAIN in the A$$ to check and fill on this bike.. Thanks
No, you can not add TPS and update software. Software is only available from factory when made for the model.....Noted it IS a pain to check air....Doc
@@LowCountryHarleyDavidson Thank you!! Im wondering if I can just add the angled valve stems 😬
I had 37psi in my front 40psi then tried 42psi in rear tire (cold) prior to riding my 2020 street glide.
It was 82° out. Wife on back, our leathers in bags, im 190lb shes 125lbs.
My tpms was reading (HI TIRE PRESSURE) in rear.
Why? Not over weighted or over inflated. Back sat in garage for a week. I check psi prior to any riding.
Thank you for the comprehensive detail you put in to your videos. I have a question closely related to this topic. I own a 2020 ultra classic. I recently made some changes, specifically, I change the front tire to a fat tire. In this video you mentioned that the sensor is calibrated and not interchangeable. As a result, I get a low tire pressure notice on my display, FR26 appears on the odometer display and finally, both tire icons remain lit in the MPH and RPM display. Is there a fix or bypass to correct these issues?
Since this video, HD has commonized the sensors. but I believe the internal Software for the Vehicle (it knows what model and tires this bike should have) will get in the way of modifications. If you are willing I believe the TPS can be shut off so the indicators won't be in your display...Doc
I can't wait to HD has a occupant sensor install so the air bags don't deploy accidentally. The wheel sensors are a great thing....I needed one the other day when I was riding I felt a thump thump as I was cruising.. ..lol
I have to old fashioned “Hurting Knee”system...look at tire, get on hands and knees, plug in gage to tire valve, read #, add air.
I understand changing ABS wheel bearings when changing wheel size but i don't understand how the tire pressure sensor would be affected by wheel size. I have changed wheel size front and back on a CVO and the system seemed unaffected. Mounting the sensors in the new wheels was a issue because of the size and location of the valve stem holes in the aftermarket wheels but the sensors can be mounted to the wheel separate from the valve stem. The stem has nothing to do with the pressure sensor other than it is what is used to mount the sensor to the wheel.
Hi Doc
My friend has a CVO2016
Lately the infotainment center has been getting the wrong tire pressure info. Suddenly the pressure goes up, then down (the yellow light for flat tire also shows up).
Could this be a bad sensor, or could this be a battery problem in the sensor?
According to my dealer there is not much that can be done 😞
The dealer is correct. There is no adjustment and the battery can not be replaced. The sensor itself must be replaced. I would say you got your moneys worth being 7 years old….Doc
@DocHarley , I’m in a hot climate and my rear tire regularly hits that 52 psi where the Tpms reads “HI” instead of a number. Does that mean it’s too high to ride on or just to high for the sensors to read. I’m always worried about that and in the past I’ve stopped and let some air out to bring the hot psi down to say 48. What do you recommend.
First when it comes to tire pressure. Purchasing a top quality air gauge is the first tool to buy. Second as you have done, research the correct tire pressure FACTS. Then set to those figures.
You are correct. The pressure sensor has a limit. This does not mean the tire is compromised. As long as the Cold pressure was set correctly the tire will perform correctly…..Doc
Amused that it takes TPMS to finally install angled valve stems. Shame these cannot be used without the TPMS sensors. Approved Angled factory valve stems would be appreciated for those riders that cut their hands on wheel edges when checking tire pressures. IMHO
Good information Doc--thanks--
Yes I have a 2017 straight line engine light keeps going on and off I’m trying to think it is the fasteners they want to charge me $250 at the dealership at Barthels holiday with
Have 2020 cvo and love my toys. I like to use Dyna Beads to balance my tires in past bikes and my vintage bikes. Its not liquid like the "run on" products. Would dyna bead type products be a problem or even just a possible concern with our TPMS ? I
YES
I wish I had known more about this technology before I bought my Harley. I hate the stress and would rather ride than deal with watching my indicators. Im going to sell the bike and get an older model.
I am sorry to hear this. The new technology is supposed to help you enjoy the ride. But if you enjoy the daily tinkering on the Old School stuff enjoy Big Daddy....Doc
Hy Doc! I do have a question for a video (maybe). I have stock 2009 FXSTC with 75000km on it, bought it new and always maintained it myself for lack of alternatives. Almost every time I start the bike, cold or hot, the oil dipstick literally jumps out, flying in the air... It started happening at around 60000km... Am I looking at a pressure problem between engine and oil tank? Or is a gremlin hiding in my bike?! Thanks a lot and a big cheer from northern Italy! - Luca
@Rick Simpson it's the super foolproof softail cap! Just the cap with the dipstick that rests in the oil tank under the seat! I'd revalue all my life choices of I screwed up fitting it! 😂😁😊
I would start first with a new dipstick and look into your air cleaner breathers (in the heads).
@@LowCountryHarleyDavidson thanks!!
Hi Doc, can this system be put on by the dealer ? On a harley that did not come with it from the factory. 2014 CVO limited. Thanks as always great stuff.
No, the TPMS is software that is installed at the factory during production.
How do you reset the TPMS warning?
That should be in your owners manual. If you don’t have one. Swing by your dealer and ask…Doc
Bought a 2022 CVO limited..5 days after delivery, low air pressure warning came on for front tire at 30 psi..filled it back to 36 psi..3 days later, warning came back on and says 29 psi..can I blame that on temp or could it be a slow leak?
Slow leak. You can take it to your dealer for inspection. In the mean time, fill to 36. Make a spray bottle of soapy water, shake and spray all over the tire, rim and valve stem. look for bubbles....(by any chance have you installed custom valve caps?)...Doc
@@LowCountryHarleyDavidson I haven't installed anything on it. Everything on it, came from Harley. I made an appointment at the dealership to have it checked. Thanks for the advice!
Thanks , seems complicated
Hi Doc, on a 2020 RG with TPMS, if I set correct tire pressure cold when the bike is ridden 5+ miles it's 5-7psi too high. If I set it hot the Tire pressure warning light is on the next morning. Which is correct procedure?
Check cold. Hopefully you are not using the monitor system to fill. Ask a few friends to borrow their tire gauges to make sure your gauge is correct. Are you following the owner’s manual chart for temperatures adjustment to correct psi application? Thanks ~ Doc
How often should the batteries be changed?
I do not know….Doc
My understanding is the sensors last 5 years but my thought is at 4 years have the shop check your battery level. I wonder if there is any tpms monitor that can do that, like maybe on the Infotainment.
@@alvingallegos6367 Thanks
Cool
FOBO
🤔
If only all YT Vids were as thorough and concise and informative as yours tend to be. Everything we need to know and nothing we don’t. And mercifully without background music! Thanks much.
I did not know about the factory shipping with the TPMS set to off mode, Can my dealer turn mine off for me? I would rather go old school on this.
Hello Doc, I recently purchased a 2017 Street Glide CVO the is equipped with the TPMS, however it is not reading the tire pressure. After watching you video, I removed the seat to find the antenna to changed the battery. I did not locate a device similar to the one in this video. I did locate a clear cylinder shape device about 2.5 to 3 inches long with a red wire at each end of it with the letters TSPEC. Would this be the device?
No that’s does not sound the same…Doc
I have a 2023 Road Glide 3 Trike and it rides terrible. My wife and I weigh 270 together and I would lkie to lower the air pressure to 20 pounds in the rear tires. I have researched that it is suppose to be alright at that pressure. I haven't tried it yet, but I bet it will trip the tire monitoring system. I don't care to look at the warning light all the time, but want to help the ride. Can the monitor be set for a different pressure? What is your suggestion's.
Don’t mess with the tire pressure. It is already too low in my opinion. You are correct, HD suspension is way too stiff for your weights. Look into a better suspension with more adjustability…..Doc
Doc, have a question on tire pressure. I have a '15 Ultra Limited and the manual says 40/36 (rear/front) cold pressure. On really warm days, pressure goes to 46/42 - is there a high side pressure that I need to watch for ? I want to set my aftermarket TPMS high pressure warning accordingly. I ride single only. Thanks - great channel.
I believe the unit will tell u when you have reached the limit of the monitor. The high number is really not that important. It is the under inflated number I watch….Doc
I changed the battery on my 2020 Road Glide Special. Now my TPMS does not read pressure. What do I need to do
It should have not “reset” those units. You will have to return to a dealer to have them put in “Active” mode….Doc
I there a way to reset the monitor without taking it to a dealer. I have about 150 miles on my 2020 road glide and it says I have a low back tire pressure. Checked and it's all good.
Thanks for the presentation. I recently bought a 2020 Road Glide limited and wanted to put in Ride-On in the tire to protect, balance and seal. I've used that product for years on my other bikes. But when I asked the dealership, they said no, not with TPMS. Not that I didn't want to believe them, but they didn't seem sure. You just acknowledge that it was not a good idea. So glad I waited for more confirmation. I appreciate Harley putting out information like this, I have an Indian too, would like to see them do something similar. Happy New Year!
Can I change my GT 6.5 to the GTS and install tpms on my 2018 road glide ultra!
🤷♂️….Doc
My tire system is going berserk it's not accurate I have 38 in the front tire and low tpm is still lit .it's very annoying . how do you reset the tpm. Also the code will not clear as long as that is lit. Will removing the main fuse reset the TPM or disconnecting the battery?
A tool is used at the dealership. How old is the motorcycle. Sad that the monitors have a non replaceable battery. Like everything else that runs off a battery…things go wrong as the battery gets weak…..Doc
My bike is a 22 road glide special. What I did is I pulled out the main fuse disconnected the battery waited then put everything back hoping to reset the TPM, The TPM showed 33 & 36. I drained the tires down to 22 lbs to see what the reading was ( 1 lb off) then as I put air in I kept checking the pressure to see if it matches my gauge( i tried 3 different gauges) Tpm showed the pressure right away. TPM is a pound under what the gauge shows. Being it was 81 degrees in the garage I set my front at 37 and my rear at 41 . The TPM is showing 36 and 39. I havent rode the bike yet to see exactly what its going to read. Do you know the dealer told mea while ago to overfill the tires!! it yeah right they said the TPM has been a problem but they wont fix it. Typical Harley dealers sell you a bike and don't want to do any work on it.
Doc, out of curiosity, you mention the RF antenna under the seat. Is that incorporated inside the BCM? I've had issues on my 2020RGL with the Red Security/Warning light on, and the Tire pressure indicator blinks and throwing Coo83h, C2000h, and C2001h. This results in the front and rear displays showing - - and no pressure associated. Have had it at my local harley dealer several times over the last year. @Low Country Harley-Davidson
Thanks much....
What’s the scoop on tire pressure and heavy riders. Between myself and my wife we are overweight and on longer trips my rear tire pressure goes up quite a bit. What’s the max? Should I compensate by dropping a few PSI? I know the obvious solution is to lose weight but until then…? 😆
The information you seek is on the sidewall of your tire. IE: Dunlop 407T
Max load 1019 LBS. at 42 PSI COLD…Doc
Consider going Darkside with an All Season steel belted radial from your local Les Schwab tire dealer. It will easily handle the overloaded situation from riding 2 up with luggage.
Garmin GPS also has a tire air pressure monitor system for motorcycles that don't have a factory system. I have a Garmin 595LM on my 2011 Street Glide with tire monitor front and rear, it seems to work and when or if a tire gets low it talks into my helmet head set.
Great info Doc and as always, Thank You!
Great video doc. Not many specific info about Harley’s TPMS, thank you.
My question is can we reuse the TPMS sensors from the stock wheel to another Harley OEM wheel?
After exchanging the sensors do we need any specific tool to calibrate the sensors?
How can you turn off the RDRS and/or tpms on a 2020 Street glide special? My lights are on constantly. I don't want any of it!
You CAN have the HD factory TPMS installed on touring bikes and the readout display activated in BOOM GTS and odometer.
Thank you for this update...Doc
The odometer needs changing out right? My understanding is odometers with an idiot light are exclusive to CVO's, right? If one has a non CVO bike is subject to Harley's restrictions to only sell CVO parts to a CVO owner.
More tech=more problems
I’ll stick to checking the tires manually via the stick 👍🤣😎
Thanks Doc!
I'm good with my stick gauge. lol..
Keep up the awesome videos doc! ☮
I have 2016 cvo road glide my rear sensor is not showing any readings can we change the battery on
IN SHORT!!!!!!!! YOU DON’T NEED IT. IT IS NOT ACCURATE AND THE BATTERY WILL EVENTUALLY DIE.
Wow high tech. I feel low tech with my old EVO lol!!
The Tire Pressure gauge will never go out of style….Doc

Pulled 50 amp fuse to I assume reset turned bike back on PSI front and rear were blank after 20 sec ride they were reading the same PSI again? Any ideas? Thanks
I have a video about changing setting from metric to US.. Are you able to do this with your bike? I want to confirm if there is a clitch in the software or transponder....Doc
As always, I could hunt for information all over the web but not find the straight goods and most accurate and concise info until I watch a Doc Harley video. This one answered all my questions and more!
Thank you. I must suggest you continue looking up information. More developments have arrived since this video came out…..Doc
Thanks Doc, great explanation of the system. Props to H-D too for making a system that is smart enough to save battery life. Question: should (can) the battery be replaced at each tyre change?
The battery for the TPMS is not sold separately, it is a complete unit.
I use a FOBO2 system on my 2018 FLTRU, works great. Had to put in steel tire valve stems.
Thanks for sharing….Doc
There all space ships now just another thing to break and cost big money to fix I’ll stick to a little older bikes and check my tire pressure 🤙🇺🇸
Doc, I have a 2020 tri glide. Not the CVO model. Can I install or dealer install, a TPMS system on this bike?
Great info for those with the system on their bikes! I’ll stay with my old fashioned gauge!
gauge doesn't tell you tire info while going down the loneliest road you ever known.
Thanks Doc, you're amazing! Glad I don't have a "nanny" system on my bike!
System seems kind of useless, limited battery life, so when the battery needs to be changed it’s going to cost you at the dealer for the change out, there are plenty of third party TPM’s that the battery is in the cap and you don’t need all the other calibration garbage.
I’m glad I have the TPMS. Started my Street glide the other morning and got a low rear tire pressure warning. 23psi. I looked at the tire and thought no way.
I checked the pressure and sure enough. It was way low, so I looked more closely and found a screw in the tire tread. Did a quick plug repair and been fine ever since. Without TPMS I would have ridden off that morning and had a flat tire or worse later that day.
Thanks Doc,
really enjoy your videos..
question for you sir..
any way to disable TPMS on 2020 Touring Model.
i installed custom rims (stock size's)on my 2020 limited.
due to no chrome sensors available and wouldn't mount anyway.
i chose not to install..
is there a way to shut off system ,?
problem being : cant read miles logged on odometer and constant flashing warning lamp
odometer just shows FR 00.
thanks for any help.

Great info Doc, I may have missed it in the video but I need a reset. I have CVO 2019, an issue from cold (slightly low 33-34 PSI) on front tire to road temp and low light comes on and stays on. I have tried to inflate to 36 while cold later and light still will not go off. Can I reset some how? Thanks
I love watching Doc Harley - he is extremely knowledgeable. However - this review on the Harley TPMS system left me wondering how to setup thresholds on this system. I had to go to my HD mechanic to ask this - and the reality is - you can't set the TPMS thresholds (low and high) on the *INFOTAINMENT* system console. This can *ONLY* be done via the Digital Assistant. They can set thresholds and then flash the BCM for the new values - which you will not see on your infotainment (high low values, just current tire pressure for front and back). So - this review was a major miss for Doc Harley. He didn't cover this information, which - usually he does and goes into great detail - which is why I watch him.
When the tire lamp comes on at 3 psi while your above 25 mph does the tpms transmit that immediately when the condition happens or does it transmit in the 64 second interval? I noticed a 2019 SGS has a tire lamp when turning on the key. I guess it is not operative?
I have a question will balance beads hurt the tire monitor system
YES..Yes...Yes....Doc
Way way way easier to get your head around this info coming from Doc as opposed to reading through the literature. Cheers Doc you are THA MAN !!
Love these new gadgets. Since HD quality is what it is, these guarantee work for the rest of the millennia
When I fill my tire it shows on the gts boom rite away.
Maybe a software update? This is news to me...Doc
Can the rdrs be added on ? Or does it have to be installed from the factory?

Awesome explanation, thank you!
How long does a module last.
We do not have records or facts on module longevity….Doc
Doc, as usual you cleared the muddy water in my brain. Thank you.
Doc: you need to explain why the TPS is not accurate with 100% Nitrogen. Isn’t 38 PSI of air the same as 38 PSI of nitrogen as far as tire performance is concerned? The only difference I can think of is that the calculation of how much to increase the cold tire pressure for each 10 degrees of outside temperature would be different with 100% nitrogen. Does the TPS measure temperature?
Temperature is not measured. Air is used to calibrate the TPMS. Use of 100 percent nitrogen does affect the accuracy of the system.
I have a 2016 FLHXSE. Both (first my rear, tben shortly afterward) TPMS failed. I had wild pressure readings at first then flat lined the rear, shortly afterwards, the front simply flat lined. I haven't had tire pressure features on my bike for almost a year. I keep being told that the sensors are on national backorder with on end in sight. (I have 99,000 miles on her) How long or where can I go to get this repaired?
We all are dealing with part shortage. Your dealer can do a Nationwide search of all dealers. but honestly most dealers are holding on to the parts they have. Until then the old fashion air guage will work...Doc
Thanks doc.👍
