I have a 1995 ford explorer xlt, and my tires are 235/75R15 105SR SL in size. What would be the correct pressure for these tires? I'm thinking maybe 32-35 psi. The tire is rated to go to 40 psi but thats too high imo. I dont have the door sticker anymore that rates what it should be but from what i remember they had it low at like 26 psi because of the rollover incidents back when the truck came out with the firestone tires.
