My girlfriend went in to get a single tire replaced even though it was above the tread wear bar. The other 3 tires were about 40% worn but in fine shape. The sales guy tried to get her to buy 4 new tires saying that they only had 4/32 of tread left (wear bars are at 2/32). I measured them at about 6/32+. When I came in he said that she would have to buy at least 2 new tires because, otherwise, it would be "unbalanced". Up until today, I've always had great service at other Discount Tire stores. I believe that he saw a lady walk in alone and thought he could take advantage of her. I would imagine that if I had walked in first, it would have been an entirely different conversation. It doesn't get any more SLEAZY than that. I hope that Discount Tire does not condone this type of treatment of customers.
