It says max is 51 psi what do you guys run for tire pressure in this size what is a good psi to run for grip and cornering?

I run about 45 psi front and 35-40 psi rear in 285-35-18's. That's about the best I could do and keep tire wear consistant on the street. For ultimate cornering you might want a little more pressure in the front but that will vary depending on the tire and the sidewall stiffness.

Why less psi in the rear and more for the fronts I thought the 295's would need more because there bigger.Anyways I have 275/35/18 up front and 295's out back and I have 38 psi in all of them I'm just curious what the best psi to run for longest wear and cornering and grip any suggestions?

Typically you run higher psi in the front to prevent sidewall rollover during hard cornering and less psi in the rear to get better traction. I found that with my Nitto 55's the psi's I listed worked best for performance/tire wear. Each tire model will differ and driving habits matter too.

33PSI... 40 is too high and will probably wear the centers out faster on that wide of a tire.

I was wondering about this too so I called BFG and TireRack (where i bought my wheels)

Heres what i found:

+ BFG recommended 35psi for both my 275/35/18's and 295/35/18
+ TireRack said that it was ok to look on the side of my door for the manufacturers recommended PSI, i havent had a chance to look yet.

I also asked the TireRack guy if rim width changed the recommended PSI and he said no. ( i have 9.5 front 10.5 rear)

Hope this helps.
