I run 33" with 3.31 gearing. If I ever re-gear I'm going towards 3.73 or 3.91, again if I ever do re-gear. It's not high on my wish list because I have no issues getting going or hitting highway speeds. I can chug along the interstate with everyone else and accelerate around slower drivers while still getting relatively good mpg for a jeep. Mud King XT get pretty good mileage and wear. I've been using these for over a decade (3 sets). Sidewalls leave room to desire, but I've been fond of them. They are horrible on wet/slick pavement, though.

Edit: I give a lot of credit to a racing cam and the Howell TBI for my jeep not being doggy, though.

It all depends on what you plan to do. When I had 33's and a t150 instead of regearing I swapped trannies. I came to that decision based on the fact that the tranny + rebuild + adapter to the d300 was much cheaper than a regear. Also, the t150 is geared like crap anyway. In your case, the T5 is a weak tranny so you might want to consider a tranny swap which might negate the need to regear depending on your tranny gears. By swapping trannies (depending on the tranny) not only will your gears in your axles be fine, but they will also be stronger than a higher numerical gear.

Most people who ask me what gears I run with my 37's are shocked when I say 3.73's...until I tell them what tranny I use.

I vote for 33x12.50x15s, unless you regear, then get 35s. Also if you mud alot it may be a good idea to get wider rears and skinnier fronts. like 10.50s/12.50s or 12.50s/14.00. It helps cut a patch. My TSLs up front cut through and direct me while my fat rear boggers push and push and push. But you will be dissapointed with that much lift and 32s. Stock CJS will fit skinny 33s in most cases. But with your axle ratio and 6 cylinder anything bigger would bog you down too much.
