I got 4 new tires put on 9 months ago. I now have issues with a side tire bulge. They refused to accept the idea that it could have been a manufacturer defect and insist I pay full price for the new tire. My appointment was at 4 PM. I had to wait until 8:30 PM to get the car back. I also learned that they installed my rear tires BACKWARDS (9 months ago). The service associates were also very rude to me. Never will be back.
