Bike Tire PSI: How Much Air Should You Put in Your Bike Tire? || REI

- Bike tires can handle quite a range of pressure, so how much air should you put into yours? In this video, Katie talks you though why you might choose to run your tires on the low end of the range and why you might want to add more pressure. Check out the video, and if want to learn how to choose the right size tube for your tire, check out that video: • What Size Bike Inner T...
This is by far the clearest answer that I have come across on youtube. I started commuting on a CCM. Excel 26x2.10 tire size and after after almost 5 months, I found 55 psi ( for recommended range on tire 40-65 psi) to be the ideal tire pressure, which is right around the middle of the recommended values. I weigh around 85 Kgs/ 187 lbs and my commute is on roads and sidewalks that are not exactly in pristine condition. The only flats that I had (2 over a weekend, ) were rim flats and I fixed that issue using electrical tape on the rims. I did watch your video months ago and I posted this comment because my experience with the tire pressures attests to what you have mentioned in your video.
Short and to the point, exactly what I wanted to know. Thanks!
Exactly what we want when we look up these information videos- kudos to the channel 👏
Exactly Exactly Exactly
@@marvinbrando722short and to the point, one exactly would have done. 😂😂😂.
Best and simplest explanation ever. Especially for an old git like me!!!
One more thought for those using inner tubes: Some tubes come in overlapping diameter options. For example, on my road bike, I like a 25mm tire width. My favorite tubes come in 20-25mm or 25-32mm options. I could choose either, but choosing the larger (25-32mm) is always better because the butyl won't be stretched as thin as the smaller tubes when they are inflated inside the tire. This means they will last a lot longer and be much more puncture resistant.
Great comment, i was thinking the same thing
Such a concise, articulate answer. Kudos to Katie and REI.
Love short and quick informative videos not those 20 min videos of pure boredom I never finish the entire videos
im so used to never going over 35psi for car tires that when i see bike tires wanting about 45 its kinda scary to put that much or even more lol
Car tires are wider, thus a lower pressure.. the narrower the tire the higher the pressure, for the most part. Car tires also do not use tubes... tubeless bike tires run lower pressures than the types with tubes.
Optimal bike tire pressure is as low as you can go without getting a pinch flat; over inflating doesn't make you go faster it just makes the ride more harsh. Katie is actually repeating a debunked myth.
IKR! I constantly check my bike tire as I inflate and I've never had the guts to get up to even the minimum - I have a horrible phobia of exploding tires (and BBQ tanks, gas powered appliances, motorized engines, balloons.... 😟)
Just had that same thought before my bike ride put it at 32 even though the tire said 40-70 now I can’t feel my legs.
yeah, my bike wants 145 psi 😭
@@leacebee5892so glad I’m not the only one afraid of exploding tires. 😂
Short but accurate and right on target , thank you very helpful
Nice video. A road/gravel bike companion video would be nice, although a lot of the principles are the same. A couple thoughts to add: 1. Rider weight (and load weight if you have packs on) is a HUGE factor in ideal tire pressure. 2. Rolling resistance benefits of high pressure are usually less than the benefits of having some cushion in the ride - lower rolling resistance is meaningless if you lose forward energy bouncing vertically off every little pebble in the road. Lower pressures are often faster than high pressures for this reason. 3. Some rims have a maximum recommended pressure, which may or may not be over your tire's recommended maximum pressure. 4. The tire manufacturer's recommended pressure range is usually well within the safety range; you can probably inflate a little over or under without much issue if it gives you the results you're looking for, but do so with caution of course - either above or below will increase risk of flats and/or blowouts. 5. Best practice for people completely unsure of what pressure they should use is to start dead center of the tire's recommended range and do a ride, then push up by 5 lb psi increments until riding the same route feels better or feels worse, then, starting back at the middle, lower pressure 5 lb psi at a time until it feels better or worse. Do this until you've covered the full recommended range. Using this procedure, you'll get a feel for where your favorite comfort range is (there may be more than one). Then you can start dialing in a sweet spot where it feels best for your normal riding. Then you can start playing with adjustments when you find yourself on different terrain or are adding pack weight. To do these adjustments, you'll obviously need a pump with a pressure gauge.
hb8dinwa This is the answer I was looking for.
Thanks man!
You rock my friend👊🏽love love love getting the exact answer to my question love it
Best video on this topic I've seen. For the basic question asked.
TH-cam needs more of this
Some tires say 50 to 60 PSI but in a bike tire and then some say maximum 35 or 40 so what kind of tube should I use just a regular tube and inflate that tube to the tire specifications because Tubi don’t usually tell you how much air to put in that tube but the tire tell you
Thanks. My Giant 700x42c tires only list the maximum tire pressure of 60 psi. I like to keep it at 50 psi for city streets and 42-45 psi for light off road and gravel. I weigh 186 lbs as of this morning and need to drop at least 8 more. LOL
The most straightforward video I've ever seen, Thank you!
Right on! We're happy it helped.
Thank you...
now I have a good idea what I need to do with my air pressure...
Awesome video, really well explained! Thank you
Hello and thanks for the question. For smooth city streets, we suggest a PSI on the higher end of the range for your tire. If the streets are rough and bumpy, go lower. Your bike pump should have a gauge on it showing the PSI. For more on this and lots of other bike info, check out all our Expert Advice cycling articles at: www.rei.com/learn/c/cycling
Got to love a video straight to the point.
You did not mention the effect that waight or load has on what tire pressure to choose. A lightly loaded tire (a small rider 100lbs for example) needs a lot less pressure than a heavily loaded tire (touring bike carrying 200lbs or more). A rule of thumb is that a loaded bike tire should sag or squat by about 15% of the tire's width. That is the "base" pressure, and it can be adjusted up or down as described in the video. If the pressure marked on the tire is exceeded, then you must choose a different tire.
I tend to ride my road bike's back tyre really quite soft for comfort (some people get uppity about it, but it's my choice), but it has meant that I've had a couple of pinch flats here and there when I've forgotten to make allowances for it.
Perfect video! Thank you.
I have a crazy phobia of over- inflating tires thus causing them to Boom! My mountain bike has something like 40-65 PSI reccomended however, I check my tire as I'm inflating and I swear it feels full before I even get to 30 PSI. What would happen if someone does put too much air in their tire? (Also I was near a tire that exploded from too much air when I was a kid so that might have something to do with my phobia maybe?) :-B
my mountain bike tires only feels full at 85-90 PSI range lol..
@@pokiblue5870 if I can't even squeeze the tire at 30 psi, I can't even i.agine adding double the pressure - I don't understand how it doesn't explode! 😟
It would explode like mine did at 60 psi, my eardrums were not happy
60 psi no significa que sea el doble de aire que 30 psi. Es presión, no cantidad de aire. Por ejemplo, en un auto puedes poner 30-32 psi cómo máximo, pero en una bicicleta puedes poner 60 psi, ya que al ser el neumático más angosto, poca cantidad de aire da más presión. Sentirás más pesada un bicicleta en asfalto con 30 psi que con 60 psi.
I made this mistake whilst going down a hill, sounded like a gun shot lol
Quick and simple, thanks!
Thank you! Short video, lots of info!
short and sweet. thanks!
Thanks for watching!
Fast and accurate advise.
Why do bicycle tires loose air pressure after a couple of days but car tires can easily hold the pressure for over a year?
simple and easy... thanks
Short very helpful thanks !
works great very happy with it
Glad we could help!
Amazing video.
Upto the point. 👍
Perfect video.
That was a really good video.
looked this up because I pumped up a tyre with a foot pump. Never had this happen before but a few hours later it burst with a huge bang. I don't know if it was too much pressure or because the innertube was old (like 10 years).
I would say the inner tube went bad I've had them go bad in maybe less than a year
When i pump my tire all by myself for he first time, I became anxious when im riding it. Sometimes i think My Tire has less psi even it is in Recommended range. Some times i pump too much that makes me feels like, "is it alright for this kind of road" .
after watching this video, Ill always go fo the middle of recommendation psi range
Thanks.. Very helpful info..! 👍
Thank you!
Thanks!
Thanks so much!
Thank you
Is the only advantage of going tubeless that you can ride on low pressure? Because I’m not that interested in low pressure and it seems like a bad investment in my case.
so if i go to a gas station pump and inflate to 3.5 bar which is about 50 psi
My car tyre is 2.2/4 bar to inflate
Therefor a bike tyre is pumped up more??
My mom said if you run in medium psi on your bike your tire would get worn easily, true or false?
true to a sense
To the point👌👌
my favorite store
My tyre says 40 to 65 PsI and I want to ride in city. How much PSI should I need? And how do I check if I fill right amount of PSI?
My tyre is very hard at 24 psi even though it says 40-65psi !
I'm sure it would explode at almost 40psi. Tyre is 29" x 2.35
hey man same thing with me.. I'm super nervous because it feels like it's about to pop! lol I have mine pumped to 55 psi, it's really hard
damn it i always put my tire to 40 psi even though it is 700x23... i weight at 130lbs back then now im 165lbs, idk what the tube required for the pressure should i just follow the tire requirement?
I’ve got a set of fairly smooth tires on my old MTB but there is no range. It says max 40PSI, which I feel is low. What would happen if I inflate them higher than that?
My dude don't it's gonna explode😂
Look for replacements that accept higher pressure. Also take a look at car and truck tire aging advice. I imagine bike tires have a similar safe age limit. Maybe longer just because much less weight on them. Still beware as the grip degrades over a period of years. Rubber degrades over time regardless of tread wear.
Thanks
Just blew mine up
HOW MANY POUNDS PER SQUARE INCH DO YOU PUT IN A 700c CANNONDALE SLICE RACING BIKE TIRE ?
can you recommend an electric air pump for bike tires for presta valve tires. using a manual pump, it gets difficult when you have to reach 110 psi on a road bike. i am a senior rider.
I try to keep mine at 40 psi. I have new tires and tubes, both sets. My tires say 35 to 65. I'm riding right around the minimum when you account for leakage so I think I can go up a little more?
How is the ride on a bumpy trail with psi at the high end, full suspension and premium comfort seat? Can a bumpy ride be compensated for without compromising with roll resistance?
It'll pop your tire
What about the weight carrying capacity? I cannot find any info on bike tires
Greetings & thanks for the question. Bike weight carrying capacity is dependent on several different factors, including frame design and material, not just the tire size and PSI. It also depends on whether you're carrying gear on the bike or pulled behind on a trailer. A general rule of thumb for most bikes carried by REI is 300 lb weight limit on bike, meaning weight of the rider and all other gear should be under 300 lbs. If you have questions about a specific bike/tire combo and carrying capacity, best to check with the bike shop at your local REI, or call 800-426-4840 to speak to one of our product experts. Happy cycling!
also important: freehub and freewheel. freewheels have lighter load capacity
Shouldn't it be cold tyre pressure? I see most front tyre "recommendation" is to fill it at max for front and slightly lower at back. Eg maxxis recon front is 65psi which is also the max it can hold and rear is 60psi. This is for xc bike. It's little unnerving to fill at max considering that it might heat up or the temp may change significantly when you filled it. Also, lower pressure is good for grip but you can loose tyre on cornering because it will come out of rim. Esp true for mtbs which has skinny rims compared to tyre. Sheesh... Why people never give complete information before making video.

My bike has a tire of size 20 x 2. 35 how much tire pressure shall I put mam? I'm weighing around 75 kilos
Perfect
We think so too!
Any idea why my tyre says max 120 PSI but only seems to go to 40 PSI with a pump? thanks
In you read the psi in this case 40-60 in parentheses () is the real psi for bike tires
my bmx bike is 85 -110 psi is that right? my pump only does 80 psi tho what the heck man!! which one new pump or new tires 🤔
I only go up to 30 psi in my mtb.
what is your recommended pressure for road bikes?. says 100 psi on the tyre wall. he usually fills 108 psi. we live in a hot country . outside temperature is around 35 deg centigrade (86 Fahrenheit) . 700x28c tube
Keep waiting for the answer.
REIcan’t recommend lower because of the liability and the manufactures warranty
In reality it’s right around 25 pounds of pressure going downhill mountain biking maybe even lower depending on your weight if you run 40 pounds you’ll be bouncing all over the damn place and he won’t be hard for you to stop
Nice
My tire says 65psi. But it already feels like it's going to pop at 50. I just left it at 50. 65 seems a bit of a gamble with tires now so expensive
My tire says 65 and I got scared so I walked away when it was filling up 🤣🤣🤣
@@RockyJayyy 😂😂😂
Great video for beginners
Jo information u
3 bars for new fats and skinny tires, and if the tires are old then 2.6 bars
I have 29 in" bike tires and it says to inflate the 40 would I be able to inflate anymore or just stick to what the tire says

How do you use a gauge and how do you know how much air your putting in
Hey Samuel! Attaching a tire gauge should be similar to attaching a tire pump. Also, when you attach a tire pump, you will get a reading on the current pressure in the tires. These two videos should help. Of course if you have more questions, feel free to give us a call, chat or visit in-store. bit.ly/2QUujfV

How is your 40-50 but my bmx bike says 65 and its a 20x2.4?
my tire said it was rated up to 60 psi, and I only aired it up to 50 and exploded out the side
Sir my maximum psi is 40-60 psi on road chalana hai kitna psi rakhu mai tyre pa
Does it come assembled
does the tube matter?
Everything functions properly th-cam.com/users/postUgkxHL1v1R3NE5x4KiYfyt8dnQmyNYz7qi5L Nothing was damaged in the box aside from a decal on the fork. The decal was missing a piece of a corner but I ended up peeling them off anyways. Assembly is easy BUT make sure you tune up the derailleurs. Both the front and rear need adjusting. I'd advise going to a bike shop but I opted out and put in 10+ hours with the help of TH-cam. Ended up fraying a shifter cable but all in all I learned from the experience. The Brakes work well but the front caliper needs adjusting or at least mine did because the rotor was rubbing against the pads. Make sure you swap out the seat, grips, and pedals. For the short run you'll be fine though. I've read that this bike isn't built yet for hard trails but I just need it for the city. PA has some of the worst roads and being in a mountain this was a great choice. Worth the investment!

Why on earth wouldn't you include a Road Bike portion? Also a about tire pumps....is the lever supposed to be up or down to like it place
I put 40 PSI to my bicycle tire and It exploded… My friend said 40 PSI is for car and vehicles. Not for Bicycle.
How often i have to check pressure of the tire in a bike.
Great question, Enam. It will depend on how often you're riding. If you ride daily, once or twice a week is a good idea. If you don't ride frequently, check before each ride.
@@rei thank you
This looks a lot like the trek store in Johnson city Tennessee
Mine blew up at like 30 psi
How about when my tire is filled to 15 psi and it feels full? I feel like the recommended range 40-65 would pop it! Any feedback would be appreciated.
Check with a 2nd tire gauge to make sure the 15psi is accurate.
Anybody watching this that has survived Corona?
My dad beat it
yeah twice
I love your help about this but how can i know more about you ?
Get in line buddy!
Hope I knew this before blasting My tire😭
need a replacement tire
LOL, I had no idea that this was a thing. My bad.
I don't know cycle air
More pressure doesn't mean less rolling resistance.
Why do hypermilers keep theirs high?
@@jasonlisonbee How high?
@@brauljo On a car, often overinflated so there's a slight bulge in the center of the tread. I like it just low enough for the tread to wear evenly. I just watched a video on the subject with someone who optimises pressure for professional bike racers. Learned some things. th-cam.com/video/asEYkpW0vwQ/w-d-xo.html
@@jasonlisonbee In that video at about 3:05 th-cam.com/video/asEYkpW0vwQ/w-d-xo.html Russ mentions research from Jan Heine, who's done fair bit of research on tire pressure and width. These are a couple of his blog posts where he talks about tire width and pressure, the main point being the lack of consideration on suspension losses that previous tests suffered from: www.renehersecycles.com/12-myths-in-cycling-1-wider-tires-are-slower/ www.renehersecycles.com/myth-16-higher-tire-pressure-is-faster/ Here's an interview from the same channel Path Less Pedaled with Jan Heine: th-cam.com/video/x6x5VC2nAuE/w-d-xo.html
