I'm new to the Jeep community and look forward to getting into it all. My question is, On a 99 Wrangler with a 4.0l and stock gears. I want to get a lift to fit atleast 33x12.50 if not 34's or 35's. With which tire size would it be absolutly ness. to change out the stock diff. gearing?
Thanks in advance guys.

It depends what your current gearing is and what kind of transmission you have.

Not too sure on the stock gearing but it's an auto.

Well, look at your rear differential at the 9 o'clock position and you'll see either 3 07 or 3 73. you can tolerate 33s with 3.73... if you have 3.07 it'll drag but you can live with it. So on and so forth, find out your stock gearing.

Regearing is expensive I lifted my 97 tj and put 33x12.5 r15 on and I noticed it a little draggy especially on the highway in fifth gear It was suggested to me to put on a throttle body spacer and cold air intake, it is my next mod as soon as I have enough money others I know have done it and are very pleased with the boost in power hope this helps

Your automatic is a 3-speed without an overdrive so don't gear too low or your highway RPMs will be too high. If it were me, I would go 4.10 with 33" tires and 35" tires would do well with 4.56 with your particular transmission.

It costs, on the average, $1200 or so to regear both axles including all parts and labor.

When you have a choice, buy American.

Great, make darned sure to buy your gears through him too so if anything goes wrong after the installation, he will take care of it with no questions asked.
