Discount Tire review: Flat

Went in and asked how much to fix a tire leak.. They said free. I set an appointment for next day.. Got to my appointment and they took off the tire and told me the tire was un-repirable.. I told them to put it back on and I will leave.. They told me no. They said they can't put the tire back on and showed me a lot of tire rubber in the tire.. I told them I would sign a release, just put it back on..
The tire was fairly new and I told them I needed the corporate office number.. I told them I would let my attorney know..
I told the manager they were scamming to sell tires.. They put some cheap tire on after I mentioned the police.
I had the tire checked and the garbage in the tire was not from that tire.
I will warn everyone about the tire scam!
