Been using D.T. since 1981. BEWARE! One sales guy (Brandon) is claiming to give you a $100. credit for your old tires (all 4 of mine had 5 to 7K miles left on them) and he actually gave me $25. in credit (which I found out 3 days later). Please go to their web site first and price your tires before you go in for an appointment. Hopefully, they will honor their promise. This is a credit on the tires only, and not any other charges.
