Hey guys, I got a flat tire the other day. I was in the front drivers side. I ran over a screw in my own driveway. The screw was attached to a stip of plactic so I knew right away & was able to change the tire without letting it go flat. I plugged the hole and sprayed a can of fit it flat to seal it. However the stuff never dried so I took the tire to a shop and had them clean out the stuff b/c the tire was off balance. ANYWAYS when the guy went to put air back in I heard 2 pops! and went over to look. 2 bubbles appeared in my side walls!! Does anyone know what caused them?? Is it covered under warrenty? Im dont want to shell out a $150 for a new pirelli 7000ss thats only 3 months old! THANKS for any help guys!
