I read your post about your tire and wheel inquiry. I can tell you that I have an 02' TJ Sport. The suspension is stock, the wheels stock 15 x 7 with 225 75 15 Tires. Which is roughly 28" diameter.
I recently changed my wheels to 17"x 9 with a +12mm offset
Also I have 1.25" wheel adapter/spacer mounted behind the wheel
The new tires are 245 70 17 which is about 31.6" diameter and 10.5" wide.
I have NO rubbing whatsoever , even on hard turns. The new set-up fills the wheel well nicely. However, the tires do extend beyond the fender flares a few inches. Just an FYI, I hope this helps you or anyone.
Happy to Help
