As I was pulling out of my drive way I noticed my passenger rear tire was flat. After stopping by QT to put air in, I noticed a massive nail... sure enough just my luck. This was the third time the same tire has had a nail in. So I look it to Discount and to my surprise there was no wait, they helped me right away. Quick and easy process and the best part it was free. They gave me a whole brand new tire since the hole wasn't repairable. I don't know why it was free, I never bought any warranty. I am assuming the tires themselves have a warranty (the tire was less than a year old). I will never buy my tires from anywhere else ever again. I am a customer for life!
