Tow vehicle tire pressure discussion

[2nOZ]

Looking for opinions from those of you that have been towing awhile. Several of the neighbors own TT's and have different TV's such as F250, Ram 2500, Etc. All of us have tires that are rated at 80 psi and load range E. My door sticker recommends 60 psi on the front and 65psi on the rear. My neighbor's recommends 65psi front and 70psi on the rear. We have also heard and read that when towing you should inflate to max rated pressure on the tires. So what, in your valued opinion, is correct for proper operation? The responses will be a great talking point at our next get-together. Thanks in advance.

the factory puts on their sticker the tire pressure that gives them a good ride and improved mileage for their calculations.

Unfortunately I have not been able to locate an LT that will fit under my truck with the larger factory rims, so I am still running P tires, factory is 35 psi all around. My new tires suck! They must have a softer sidewall than the original OEM. Through trial and error, I found 40 psi in front and 45 psi in the rear fell nice.

I know a lot of people that tow, and many of them adjust their tire pressures to accommodate their load.

I keep mine at the recommended pressures that are listed on the door pillar -

60 psi front
75 psi rear

Load range E factory tires.

I run "P" rated truck tires. These are not the same as the "P" rated tires on cars. They have stiffer sidewalls and a higher max psi. I have Yokohama Geolander AT/S that can take a max of 51 psi.

When not towing I keep 35 psi on all 4 tires as shown on the door sticker.

When towing I keep 35 psi in front, and 48 psi in the rear. It tows nicely and I have no wobble.

Door sticker recommendation is for normal daily driving. Note, recommended. Everyone has their own needs and has to figure what type of tire to use, and what psi is best for their application.

I run 65 in front and 80 in the rears per the sticker.

I have pondered this dilemma for years. I happen to be lucky enough to have a very large compressor in my garage and a very long hose line. I also have a very high power portable compressor I can run off the truck. Since i do a lot of off roading and hunting and back country stuff I am constantly airing down my tires, and airing them up. When I am towing and hauling a load of wood, I air my tires to around 5 PSI from the max on the sidewall. This just happens to be 5 PSI above the whats listed in the door jam.
IMHO, I say to air the tires up close to max if you are running with a heavy load.

I run mine at door sticker + 5psi. at all times. I never change pressures.

have 2007 expedition running transforce 6 plys. at my mechanics recommendation ( he has plenty of towing experience as well) running 45 front and 60 rear, so far has been spot on. can be a little bumpy when not towing for folks in back seat, but that is not very often.

I put in whatever the sidewall on the tire calls for. I don't go by the door sticker since I feel that was printed when the truck was delivered, based on the tires on it at that time.

I air down frequently for off roading, but run full 'spec' pressure at all other times. That's just what we do... I wouldn't be comfortable going higher pressure than the tire manufacturer has stamped on the tire. Interesting topic though, I never gave it much thought.

Here's a nice article on this subject from Tire Rack. You'll also find similar information on every major tire manufacturer's web site. Unless you deviate from the OEM size there is little reason to deviate from the recommendations on the door jamb for normal daily driving.

Thanks for the informative article. My truck, as well as my neighbors, all came with 20 inch tires as standard from the dealer. My door jam calls for 60 in the front and 65 in the rear. I will set the pressure there and give it a try. My neighbors pressures are slightly different so they will adjust theirs. Thank you to all that have responded. Happy camping!!!

I run 34 (cold) in my tires daily. When towing I adjust to 40 (cold). I have E rated LT All Terrains

My sticker for my 2016 Ram 3500 says to run 80 in the front and 65 in the four rear tires. Seems kind backwards to me.

[repacs0103]

I tow a lot and carry a plow in the winter. I run 80 all the way around. 2011 F350.

I run whats on the tire sidewall since they are not the same as original OEM tires.

[dewey02]

2002 Dodge 3/4 ton 2WD.
Door sticker says 50 front and 80 rear.
Original tires were Michelins. Now have Michelin Defenders.
I run at the sticker pressure when towing the trailer. (80 is also the max tire pressure on sidewall)
When not towing, I run at 45 front and rear.

I run what is on the side of the tire.

[trailerCaptain]

My Ram 2500 has a button for the TPMS that changes the tire psi limit up around 20psi for towing heavy loads.

[Atlee]

My tires are OEM 17" LT tires. Truck placard says 55# front, and 60# rear. That's what I use, even when towing.

I've never felt any adverse effect with the tires aired at that weight.

[Popcycle]

I follow the door sticker numbers regardless of the maximum tire rating. If a manufacturer specifies 30 psi and the tires are inflated to 60 psi while this might help with sidewall stiffness the amount of tire actually contacting the road decreases by half. I must assume the engineers knew how much tire contact my vehicle needs to handle and stop safely under varying conditions.
