Can you stay in 8th or does it constantly have to downshift? Did you get a tazer to do tire size correction?When I first got my JL, I put 35" Toyo MT's on it. I drove it with 35's for about a month, then after wheeling it a few times and dragging the belly over rocks too much, I decided to add a little lift. I found the Mopar lift for $795 online and ordered it. I had planned to stick with the 35's but after installing the lift, just felt the JL looked stupid with the 35's and 3" of lift, so I ordered 37x13.5 Coopers. I live in DFW too and commute about 30 miles on 121 to work. Unlike the JK which definitely felt slow on even 35's, the JL doesnt seem to take much of a hit from even 37's. I still drive 85-90 every day to work. I'll probably regear at some point but so far I don't feel a huge need to do so. I'm running 37x13.6 Cooper Discoverer STT Pros on 17x8.5 Mopar Beadlocks.
