so i bought a new tire online brand new pirelli i found for a good price. Installed on monday and the tire was rubbing hard on the fender the past few days when i hit bumps. I was gonna go for a fender roll today to correct the issue but i noticed my tire was really low on air. i filled it up with air and now it's low again. Is the tire done for? i don't see any shreds or holes

 

I had a similar problem recently. I turned out it was the valve stem. It was loose and causing air to leak out. They rebuilt the valve and it fixed it.

 

I've been running it since monday and it just started happening today. I'm thinking the constant hitting on the fender caused damage. When I go for the fender roll I'm gonna see if they can inspect the tire for me. If it's unrepairable I'm gonna have my ugly stock 17 for now and have the $120 go down the drain..

 

Best to take to an installer and have them check it out. They have all the tricks to finding leaks you normally can't see.

 

yea the leak was on the thread not on the sidewall, had nothing to do with the rubbing. 4 day old tire and already having bad luck. They put a plug and is good to go now. Still gonna get a fender roll though
