Tire Hit fender lip

Perhaps it is one of the issues mentioned above but also keep in mind that Ma Mopar never had a solid reputation for centering her rear axle assemblies in her vehicles. I have seen some that were an inch off to one side. Many people just go with what was recommended by others but the truth of the matter is that you have to measure both sides before trying to stuff in the largest wheel/tire combination back there. At that point (if there is a discrepancy), you can choose to correct it or go with the tire/wheel combo that will fit the tightest side. Good luck.
