Just wanted to say thank you for all the help guys, I went ahead and pulled the trigger on the Wrangler Authoritys in the 31x10.50 size. I am so far very impressed with them. Put 113 miles on my truck today both interstate and back road driving. Not too noisy on the highway and great off-road. Didn't affect my power too much, in my opinion 3.08s just aren't great in the first place unless you spend all your time on the highway. Mileage seems to have not changed too much but I will know more as time goes on. So far am very happy, will have pictures up in the picture thread probably tomorrow.
