Tire pressure

[Mountaineer1954]

Do any of you out there put a few extra pounds of air pressure; above the normal pressure; in your back tires when you are towing ?

I do, I air up to 45 psi on my BFG KO2 LRE tires. Firm enough to help, but not too rough a ride.

I run 36 PSI cold in my Durango. When hooked up to the trailer my TPMS shows they rise to 44 PSI on the road. Door sticker calls for 33 PSI.

The max rating is when cold. The tires can handle then hot psi.

You are correct, I edited my post.

One truck calls for 35 psi and the other 32 psi. That's what I always run them at. I see no reason to up the psi when I'm within all the weight limits

I typically go a few PSI (usually 3, max 5) over placard in all 4 tires (and the trailer) when we are changing altitude. If we are going up, it gets considerably cooler and we lose pressure. If we are going east, the extra air compensates for the higher ambient pressure. Since we are pretty close to payload with the tongue weight added, I want to make sure we stay at or above the placard, regardless of outside temp or altitude.

This has never created any issues, or uneven wear across the tire tread. I air the tires up the morning we are departing here from Colorado Springs, and just do a back of the hand temp check of the tires and bearings when we stop for fuel or food. I don't check pressures on the road unless something happened.

Voice of reason right there.

I base my PSI off scale weights and a load and inflation table. Good traction, tire wear - and safety. A chalk test can also work in lieu of a scale.
