First step is to go here: http://www.grimmjeeper.com/gears.html

Plug in your current tire size and gearing on one side (and trans, etc.), and then try 4.56 and 4.10s on the other side and compare the differences.

If you have the T5, I'd go with the deeper 4.56 gears with 35s. I have 4.56s with my 32s, and I love it. I went deep with the gears so I'd be ready for bigger tires. 35s might be going on the CJ this summer-

What engine and tranny? I have a 258, T176, 4.56 for my 35's. I like the combo. Mine is primarily offroad though. If it was a DD or primarily a street jeep then I would look closely at the 4.10s. I really like my 4.56s though and every chart I have seen shows it's right in the proper gearing for my tires. What tires are you running? Just because they say 35" on them doesn't mean they are. Most manufacturers are about 1- 1 1/2" off.
