Tire psi

[Canadian Expy]

I was wondering what People are Running for Tire PSI on Bigger Tires.
I`ve got some 35X12.5X20 Pro Comp X AT and was wondering what PSI to run them at ???

 

[Canadian Expy]

Dose no one have bigger tires ....or just don't run air in them
OR is it a stupid question ?????

Just wondering for running around city

i was always told no matter what size tire always fill to manufacturer spec located in the drivers door jamb.

yeah usually what the door says... but best thing is look for MAX PSI on tire and go somewere less than that... I'm around 40 PSI I believe... can't remember I will have to go look... or email ProComp and ask them

im running 265s at 38 lbs. they look to low with out that much air. even still they bulge a lot. when hot they are at 41. i think im running them to high. but they need it.

yeah, tires are usually ran at about 35 psi cold, i believe. i think that is what mine are at.

I've bought the keys already ...so I'll try tomorrow....I was told I could drop the A arms if I can't safely remove the keys.

 

[panda24619]

yeah you could. i never replaced my keys might do that. but just follow directions. theres some on line if the keys didnt come with any.
