Seems like Goodyear Wranglers are what came on my XJ from the dealer, and what I ran for about 5 sets of tires before going to the 32's. If so the 15" tires I used were expensive. They didn't wear very well for me as they would get out of balance after about 6 months. I'd have to have the tires rebalanced.

Could just have been the way I took corners.
