31s easily, 32s with a bit of rubbing, and people will hate to hear it but 33s if ya get the right wheels (proper backspacing) and bump stops. You'll likely want to get new wheels/spacers no matter what size ya go with. Refer to my sig. I'm on stock wheels and at flex at full turn I have a bald spot where there used to be paint on my spring perches.

I'd go no bigger than 31" with stock wheels, or 32" with aftermarket wheels with reduced backspacing. Not to mention the bigger the tire, the less power the engine can develop due to reduced engine RPMs. There would be a lot of work & $$$ involved to making the Jeep so it could successfully run 33" tires, I wouldn't even consider it unless you're willing to face that.

You should be able to run 31x10.5 as long as you have proper back spacing. You might look into a 2" budget boost. They are not much more than a body lift. And a lot easier to do in my opinion. As Jerry stated above, 33's require a bit more investment. I will be going to them soon, but will need to re-gear.

A BB is a 2" suspension lift which can be put together several ways... just a set of 2" polyurethane spacers, or those plus 2" longer shocks, or 2" taller springs, or lastly, 2" taller springs with 2" longer shocks. Obviously the last option is the best way to achieve that 2" taller height.

If you add an inch of clearance, you should be able to run a 2 inch bigger tire. Simple math. Making sure the tire fits within the fender and doesn't rub is the job of the wheels and bumpstops. Dealing with mpg loss etc is related but doesn't have anything to do with if they fit or not.

If your Jeep has stock 3.73 gears then you "should" regear when your at a 33" tire. But many dont and say its not that bad. Im running 33's with stock 3.73 gears with a 5speed. But it also depends what motor and trans you have and what gears.

Gearing comes down to

1. engine
2. Stick or auto
3. # of speeds of stick
4. Wich auto
5. can u handle loss of power

in general 31" tires on a stock TJ is nothing. 32" tires on a stock TJ might need gears based upon #'s 1-5 above. 33" tires on a stock TJ most likely will need new gears but is done without a gear change all day.

I have 4.1 gears and 6spd, it wouldn't be necessary for me at 33's and I don't plan on doing it for 35's either, but my jeep is different than yours and we have no idea what jeep you have. Post up what you have to get an answer.
