I have a 2011 charger I bought it used with 34,000 miles it now has 56800 mile I have had to put two sets of back tires on the back due to them eating out on the inside to the point the belts are showing. The tire are leaning in like this / \ when u look at the car from the back. Took it to a small dodge place and they sent us to their body shop and we where told they have never seen anything like this before and really don't know what could be causing it and sent us back to dodge. They had us schedule an appt with the larger dodge place in our area to see if they could figure out what was going on. Any advise/suggestions. The car has never been wrecked and the body shop states they don't see where it has been repaired.
