Rip off artists. Had our car in for two tires to replace. Earnhardt Cadillac said the back two were fine. Discount was cheaper but they lied to my wife and said she needed four tires. Then refused to put the old tires back on, saying they were not safe but they were fine. They had no biz taking the back tires off in the first place. We only asked for the front two replaced. This is another example of unethical mechanics ripping off an unsuspecting consumer with lies and fear tactics. BBB report coming.
