Just fyi on runflat repair at discount tire. At my local store I had slow leaks on the rear tires caused by nails and they repaired for free. The bad is they did not use pucks to lift the car and caused a small crack in panel under car. I did not raise to much of a deal about it, because I figured if I had it repaired the body shop would screw it up worse. Anyways about a month later the right rear tire start making a roaring sound, but stopped when turning left to right and I assumed bearings after reading forums. I ordered bearing. timkens in the mail on the way. I just left discount tire after getting tires put on my truck and while I was their I wanted them to look at my tires on the vette. I took them off car and had them in the back of truck. While looking at them I noticed that the inside of tires had been punctured in four spots on both tires which was causing the bubbles/blisters on the tire. The guy noticed the four spots stating the sords are showing in these four spots. That is when I told him they had to come from his machines and they did. They are replacing tires friday for free and I hope this fixes the roaring sound. I assumed discount tire new what they where doing, but I will hold their hands from now on when they work on my vehicles. I hope this helps people out to never assume they are the experts.
