Discount Tire on Maryland Pkwy. have a good product idea but horrible service.  I visited this store on Sept. 15, 2012 and they told me they don't have my tire in stock but if I wanted to go pick it up from the warehouse they would do change it for me. I found this to be unreliable and horrible service.  Who would say that to a customer that has bought over $1,000 in product from them.  They said \"If I want to wait till Sept. 17, 2012 they will do it for me and it would take about 10 minutes.\"  So I agreed because I didn't mind waiting two more days of riding around with my spare tire. I came back for my reservation at 8 a.m and they still didnt get my tire from the warehouse.  I rescheduled for the last time and they finally got my tire and attempted to charge me for renewing my tire warranty.  This time I told them I don't want one because I will just buy my tires from someone who actually will provide quality customer service.
