What psi....
oh, you mean tire pressure?
i thought you mean boost and didn't want to post cuz i don't have a 02 Hd so i might get flamed for it

anyway, i was running 40, and after 25K miles, its SLIGHTLY more worn in the middle than the outside, but i'll get an easy 40K out of these tires.
i've backed it down to 38 psi, and that seems to be what most guys around here run. some run less, some run more, 38's about average in the middle
the door jamb says like 35 psi on the HD's, and the tires say like 42 i think? so 38 would be fine, unless somebody else gives you a better reason to run less

i was planning on asking this question myself.
I just changed tire pressure to 38 (from 30 - dealer pressure). I think I am seening nearly 1 mpg difference in gas mileage.
