should i add a little more to save gas???

at 35psi my front tire seem low pressure compare to the rear

what pressure should i use?

 

i use 35 in the summer. and 20 in the snow/winter.

 

I put between 35 and 38 psi. I always use the highest psi that keeps the tire in the proper shape.

 

i would apreciate psi in 285 75 16 to compare

 

With oversized tires you want more psi. If you run to low it will feel real bouncy going down the road. For you 45psi might be better. I had 265/70r17's on my 05 grand cherokee and ran stock psi and it felt like crap so i bumped to 50psi and it fixed all my problems. try 40, 45, then 50.

 

truck recommand 35psi cold..and the max tire is 65 psi cold

 

I run 45 PSI in my 265/65-17

 

For a stock tire any thing bigger you should need more air. Its more of a guess and check.

 

I run 38 in my stockers... 265/60-18s

 

i run 43 in my tires.
