I got four new tires installed on factory alloy wheels and the shop made a mistake on the original install by installing one incorrect size tire. They were OK on the first install, no marks on the rims. They say no problem and replace the tire. After I get the car home I clean the wheels and find 2 spots with deep gouges 1" and 2 '' long . This is an older car ('87), but that should not make a difference in my mind. I pay the same as everyone else. How should the shop make good on this? What is done for professional repair?
