Duratracs and air pressure???

First off I finally got them!!!! I'm pretty darn excited I love them but I do get the feeling I won't get as many miles out of them as my stt's so with that said what are you guys with 31s runnin psi wise? I'm at 32 and I think they need to lose a few more pounds

I would guess around 28, that pressure sounds familiar (although I haven't ran 31's). 33lbs is the stock rating i believe, the larger the tire the less pressure needed. The best way to check is doing a chalk test. (Google it)

I've been running 28 psi in my 31 10.50 Duratracs. So far it seems just right.
