- It's insane how many types of tires you can buy for a 3/4 Ton truck. You can go from 55 PSI to 95 PSI. Most people don't realize that so I hope this video helps. If you're going bigger, check out this Gear Ratio Calculator:

This video commented several times about tire pressure relating to towing capacity, but I think tire pressure should be set by load on the tire. HD trucks have E rated tires that will carry 3500+ lbs each with 80 psi, but empty the rear tires can have
You simply call the tire manufacturer, and ask for their load index chart for whatever tire you have.
Will tell what psi that tire needs to carry whatever load.
I called Cooper, Toyo, Goodyear, etc.. all told me to the proper pressure to run was 40psi when empty, 80 psi when towing.
And gave me the load index chart for weights in between.
My truck has E tires LT275/70R18, 45 psi front and 55 psi rear. Crosses the scale at 6800 for my daily load w/o trailer. Speedometer is spot on. 2015 Tundra double cab with 8 ft bed and coil over shocks. I step up to 50 front and 60 to 65 rear when towing. 8150 in max weight rating according to axel rating. Crosses scale at 13,000 GCVW truck plus trailer. Handles well, tows well. No sensors on the wheels. Use a pressure gauge and visual inspection of tires. I’m near 70 so I don’t need the pressure idiot light. Thanks for your video !!!
What is the mpg difference? I’ve never had a set of HD tires that returned good MPG’s at half pressure. Ride was better, sure but 2-3 mpg loss.
I heard my friend that works at Blacks Tire service say there’s a ton of information on tires and there make up. You passed out good explanations on this video I had to watch this one several times to really grasp it all. Great video.
All of our 3/4 ton ranch trucks run 10ply tires at 65psi front and rear unless under trailer, then the rears go to 80 psi the one tons run 12ply tires just to be safe
Load index is everything. Along with proper inflation for the max load of tire to be achievable. I run 37x12.5r17 on 2018 ram 2500 with AEV Dualsport lift. Amazing ride with torsion front sway bar I added. I also have towed over 5000 miles in 2 years with Toyo open country m/t old range D with a 3525 capacity per tire. That’s only 120lbs less then stock E range tires. Tows great at Max psi of course. Hope this helps and you all know when you do the research it explains it all. E and D range ratings are based off comparison of tire ply’s of the old days. Doesn’t mean there is really 8 or 10 ply’s at all, those Toyo’s I run are made out of a solid piece of rubber and stamped into shape and form. Do your research and follow smart advise as is in this video and you’ll be good! Speed safely! And don’t take nowoodenickels
Do you find your lifted truck squats more when towing vs before the lift?
@@xmo552 if you use lifting blocks for the rear, the ride wouldn't change much and would squat like stock.
Well said! 👌
Great video!
Had no clue on half the info.
But just getting I to pfroad tires.
Glad I found your video to start with. 👌
Thanks for this video.
Heck of a allot cheaper than paying for air bags just for ride quality.
Thanks for sharing nick much appreciated
My power wagon I run 65 in the rear 60 in the front and it is smooth. I understand that a straight up 2500 has a sifter suspension
I have a 1981 GMC C3500 reg cab long bed 2x4. She's heavy with gear every day, she weighs 7400. I tow old american cars all the time. I keep it at what it says on the door sticker, it's 60 psi rear and (I think) 45 psi fronts on stock wheels and stock tires. She handles the weight and handles the road like a new truck.... literally zero sway or worry.
Gvwr is 11,500.
My 1985 GMC c3500 2x4 factory tow truck. Stock wheels stock tires... keep it at the psi on the door sticker. She rides great.
Gvwr is 14.5k
If I have a long heavy tow I might chalk the tires, but usually it's golden.
My 2004.5 Cummins dually. I think it's also 45 fronts and 60 in the duals.... whatever the sticker says actually.
My f450/f550 or 4500/5500 tow trucks (flatbed or wrecker) use a 19.5" tire. 80 in the back and 60ish up front. Less than 80 in the back and they'll actually brutalize your spine.
I always stick to the door sticker and with my years of driving like a dumbà§ş, loaded or not, and driving amongst other tards on the road I've had to avoid accidents multiple times daily. Stick to the door sticker numbers for best all around handling and wear.
If you go up or down in wheel or tire size it's best to chalk the tire. And, of course keep your brakes, suspension, and steering maintained ... it all affects your tires.
I have a 2018 2500 Diesel. Tow nothing and don't carry much over 500lbs. I put my rear at 45 front 58. If you do research on web they say 45 front 35 rear. Ram Mechanic says 35 rear is good 50 front. I have a tuner that can set TPM's sensors. Be smart.
Curious to hear your educated opinions on tires for 2013 F250 (6.7), in coastal NC (no snow), almost all on road driving, some towing up to 10,000. Currently have Dynapro AT2 LT325 / 60 R20. Priority is tire longevity (miles), MPG, road performance, towing, tire noise and finally off road performance.
Would like to hear about air suspension bags tire size and load capacity have 2002 f250 with firestone bags
nice video.. woulda liked to hear what your opinion is for a 3500 dually since they basically share the load in the rear.
I have a 2004.5 Ram 4 door long bed dually 4x4 with the Cummins. I stick to the psi on the door stickers and she rides like a Cadillac loaded or not.
Yep. 25% is the law actually. You might know about the TREAD act. Light has to come on for all cars when pressure drops 25%> since 2001 and by 2006 at large for sure. Go look at the stats for an old explorer or an old Xterra on P rated all tetrians. 26 PSI recommended!!! Tread act is for safety but you could argue that it ruined ride. I run 27 PSI on my metric tires. Load inflation tables say I can actually do 22 if you pretend you're going upgrading tires on the soccer mom Cherokee. 225 60 17 at 33 psi equals 265 65 17 at 22 psi in metric and 26 psi in P metric. Actually... You can take the soccer mom Cherokee and even pretend to upgrade to the Cherokee Trailhawk tires and you'll find that according to the load inflation table too can do 26 psi on the 245 65 17. So do I feel safe running 27 PSI on my 265s. Yep... You can also do the downgrade calculation from a Jeep Wrangler with 255 75 17 tires at 37 psi (because it's LT ) and you'd land at 27 PSI on the metric too ...
On LT , the lowest I'd go is 35. That's where an LT bottoms out. If you run lower than that on the street they could get too hot. LT tires take about 10 more PSI than metric or p metric tires . That's the rule of thumb based on many calculations I've done. That's why the PSI is so high on those trucks. Stiffer tires take more air to inflate them to produce the lifting force. That's my analysis anyway - pretty sure it's correct. It's like blowing up a thicker balloon - it takes more air to do it.
All that to say , whatever you do on an LT , just don't go below 35 PSI unless the tires are REALLY big and then only do it if the load inflation tables say it's ok. It has to be 35 inch tires or bigger on a 4000-5000 lb vehicle to go under 35 PSI on an LT basically. Even then it's going to be about 30 psi if you're running 35 inch or 37 inch tires on a Wrangler.
Soo many number combinations.
what happens if you have a 2005 f250 occasionally tow a trailer, and you use 55psi on a load range E tire... 285/70/r17
Sounds fine to me. As long as you have the weight distributed well, and you’re not slamming those rear tires, you’re probably good. And obv you’re not hitting the max tow rating.
What experience are you basing this information off of?
We have a dually f350. Our slid in camper sits at 5000 pounds. Payload now towing. Is 65 -80 psi all safe ?!
I would run whatever the door says. That’s a heavy load.
Just drop the psi to 55 on my excursion, at 65 it was too bouncy ,
Just going to casual flex in the comments about owning my dream vehicle?
@@NickMango it’s a fun vehicle to upgrade, about to buy new 20 inch rims with 33 tires that’s how stumbled into your vid.
What engine/year is it? I really need to find a clean one and buy it.
An SUV with a notch cut out of it, haha! Love it. I've always said you can't get any work done with a 1500.
Lmao. The new 1/2 pickups will haul just as much as the early 2000’s 3/4. 🤡
I need youre help please its urgent
My solution was to buy a truck that has no TPMS. Let the good times roll!
That’s a good solution haha 👍
“A half on truck is an SUV with a notch cut out of it”.
What a load of baloney. Half ton trucks these days are twice the truck of 20 years ago, both in dimensions and capabilities. You can thank the EPA and C.A.F.E standards for this fact.
You missed an opportunity not to speak when you don’t know what you are talking about.
You missed an opportunity to pay attention before commenting. The point I made was about ride quality, not capability.
PVC pipe under the hood 😂
People are doing it haha
I got a 150 and run 31 in back 12.5 17 35
