On 9/21/19 I bought a set of tires at the North Richland Hill, Tx store with road hazard warranty and 8 days later I got a nail in my tire and I took my car to receive a new tire and I was told that I had to pay $45.47 to have it replaced. So what the hell is the road hazard warranty for when buying a brand new set of tires. I spoke with some guy name Zack and he gave me some made up story about tires being prorated.
