I just bought my 1st wrangler ('02 sport) and it came with 31's. I have been told by several to run with 26-28 lbs of pressure. Tire companies say 35 lbs. Jeep seems to rides stiffer with 35 lbs. I tried 32 lbs and seems to soften the ride some. Right now I am doing all onroad driving. Those with 31's....what pressure are you running?
