hey guys, well I am the proud new owner of some 34's with 3.73's gears with a Sparton... so after reading a few tire threads.... what are you boys with NItto Terra Grapplers running your psi at?
Thanks,

two words: chalk test

i ran 35 psi and got good life and wear out of them but it's different for every truck

The only other thing to do would be to inflate to max psi and slowly release the air until the tire sits flat. Beef has suggested this to others and its a sound theory.
