I have a 2010 sport and it came with 225/75/16. I bought some bald Sahara take off for the rims and purchased some 255/75/17 for it. I wish
I would have gone to 265 or 275. Yours are 29" roughly and 255 I put on are just under 32" diameter so the Jeep is 1" to 1-1/2. If you keep your
factory steelies you could easily go 265/75/16 and not have any problems.
2010 JK added 17" rims and 32 inch At tires, hitch, Ace rock sliders, Barricade bumper, light guards, grab handles, floor mats, Grabars,hood latches, fuel door, 2" Rancho sport lift with 9000XL shocks, TerraFlex Monster track bar, Moog drag link, quick disconnects and Rancho stabilizer and flip kit.
