What tire pressures are you guys running when on the trails? In my previous vehicle...jeep yj and in my friends 88 4 runner, we ran around 16 or so when in the San Juans and around 12 or so when in Moab. With my new to me LX being so much heavier, I was debating running them a few lbs higher than I did on the jeep. What do you guys normally run?
