I have a stock' 13 wrangler sport with the small Rim's and tires.. I was thinking about buying my friends 10th anniversary Rubicon rims and tires... would it fit. Without having to lift it, shave fenders or remove fenders?
They should fit. However, I don't know what year the 10th anniversary model is. If it's not a 2013, then the TPMS won't operate properly. They changed the TPMS frequency in 2013. Anything prior to that won't work.
Check your speedometer against a GPS before you do anything, you may find that it was not correct in the first place and the slightly larger tire brings it to being accurate. Most speedos are off a little in that direction.
