newb lift and tire question.

Ok I'm a noob here. I just picked up my 2011 wrangler unlimited. Eventually I am going to lift it and my question is, can I install a 2.5 to 3 inch suspension lift and 33 12.50 17 tires without any other modifications like axles or gearing. I have the 3.73 gears with limited slip. If not what are the largest tires to use without any other modifications? Thanks. Love my Jeep and love the forums.

you can run 33s without any lift, I am pretty sure. with 2.5 inches you can run 35s but road only. if you have a 3 inch and 1in BL you can def run 35s, or greater. also, you can run up to 35s stock with the right fenders and few other mods. theres really alot you can do. but you can def run 33s on a very small lift. your gears will be alright with 33s. not great, but alright. most people will tell you you will want to regear. if there is anything I can clear up let me know.

On a JK you can run 33's with no lift at all. Will need either new wheels with better backspacing or wheel spacers so not to rub at full turn but no lift is needed for 33's at all. You can even run 35's if you get flat fenders or trim stock but even with a 2" lift 35's will fit. 35's only add 1 " to radius under the wheel well over a 33 and only 1.5" over stock

As far as gears, I had the 3.73 Automatic with 32.71" tires and it ran alright with those gears. Now have 4.88 and they work a lot better but wish I went to 5.13's now. But saying that 3.73 still are alright but just alright.

What do you mean with a 2.5 you can run 35s but road only? Why would that be?

I think he means that in offroading conditions with the suspension articulating more, 35's would rub some.
