What psi should i dd with???

[George_Pimpdaddy]

Hey just got my 89 blazer back on the road again with the new tranny, tbi 355, and new hedders and duals. Anyways i have no lift and no front swaybar and live in a city with bumpy roads lol. I have 31" BFG Mud terrains on the rear with my posi and 31" bfg all terrains on the front, both sets are 90% tread left. my question is what would a good pressure be front to back? thnks for any help as i want my tires to last as long as possible.

whatevers on the side of the tire

the pressure on the side isn't always the best to run, it is the maximum, imo, the best way to set pressure is to put some in, roll it forward through some dirt or a wet spot on the driveway and see if the whole tread is dusty/wet, if it is in the center, drop pressure a bit, if it is outside, raise a bit and repeat, i am running about 18 psi in the rear tires on my truck to keep them flat on the road.

32 to 35. Safer to run with a slightly over inflated tire than an under inflated one.

I run 33's and have around 25lbs in em on my dd ,seems to help the ride alot.

When I was running BFG AT's 31x10.5 I followed what was on the door sticker. 30psi-front 35psi-rear. Worked well for me.

When I ran 33x12.50/15s I ran 35 all the way around. Between that and frequent rotation/balance they lasted forever. They were BFG MTs. The front tires just barely cupped after a lot of miles. I see a lot of 4x4s with the front tires cupping bad.

I'd run them at about 28-30 for the street. 15-20 for off road.
