Two years ago we bought four new tires for my wife car here. We got the tires the salesman recommended, but when we came in for warranty work we were almost ridiculed for purchasing such cheap tires. Last week we noticed that both front tires had split where the sidewall meets the tread. We brought the car in to get the tires replaced and surprise surprise they wouldn't honor the tire warranty we purchased (other DT locations have done this too for various reasons). They stated that is was due to a bad alignment. We ended up two getting new tires and bringing the car to mechanic to get the alignment done so the new tires wouldn't wear out. Turns out the alignment was within spec and the mechanic said that would not cause the tires to split like that. Also, the mechanic stated that the other tires, the two year old tires, had broken belts and needed to be replaced immediately.
Discount Tire has affordable tires, but don't doesn't honor the warrantee. I probably will come back but next time I will not purchase the warrantee and save a bit.
