Another re-gear thread: 2004 TJ 4.0 with 31" tires

I am running 4.56 gears with 31 inch Goodrich tires. I have 4 speed auto. It drives really great. I get 2500RPM at 70MPH, which is really good in my opinion.
I can actually drive on Texas highway 75MPH (which is a speed limit here) w/o any significant trouble. It accelerates fast, and in general is a pleasure to drive.
