I went from 4 inch lift to no lift then back to 2 inch lift. I have rims w tires from 31's-33's and all are stacked in my garage, taking up space. I downsized due to my other half being so short. I then tried to sneak a 2 inch lift in but she knew right away. If you work on your own car, down sizing or going larger is easy, u just have to get a little dirty.
If your gearing is an issue, swap out a new rear end. That's takes about two hours w an impact wrench, maybe quicker... You can find good deals on differentials on craigslist.
I run 4.11 gears and have not had any gear issues w running larger tires. My jeep does run at much higher rpms when running 33's. Im currently running 32's w 2 inch lift w 4.11
