I bought a set of 4 New tires for my car. Paid handsomely for them, road hazard included. Went two miles to my house to get something. Ran inside, came back out. One tire was completely flat. Took it back after i wrestled the donut tire on. He wouldn't replace the tire or refund my money. There was a one inch slit on the inside of the tire side wall. Don't know how that could happen. So, if someone was mad at me . They would have had to climb under my car and slice my tire. How dumb is that! Although, he did offered to patch it for no charge. Ever heard of patching a side wall? What a nice guy . huh!
