Thx for that info!!I'm running 37x13.5R20 Gladiator XComps on my 23 Sport. Wheels are 20x10 with a -25mm offset. No lift yet (wife is still healing from foot surgery) but I did add a 2" leveling kit to the front, Synergy track bar brace, and Rugged Ridge dual steering stabilizer. I also had to make 3/4" spacers to push the front bumper forward a little. Full size spare just fits under the bed between the heat shield and hitch. I do get a little bit of rub in the front at full lock and loaded down or a decent amount of articulation.
I'm probably going to do a fender chop in the near future and a 2-3" lift when she's healed. I have the factory 4.10 max tow package. My 21 Gladiator that got totalled in February had 4.10s and 35s. I don't notice any performance difference between the 35s and 37s. The JT is my daily. I have a built 99 WJ for the more serious off-roading.
