I had to replace both passenger side 21's due to bulge and flat free of charge mobile service at my house. They took to a tire store to be balanced. Question is if this is a defect in the tire or will this be a continuing problem?
Will say this, switched to my summer tires from the winters. Had 19"s for the snows. The TPMS on the original 21's that the car was delivered with were not recognized. Had to take it to Chicago service center for software update etc. On a good note the service center is really nice and there...
Stinger is more stealth but more expensive. ALP offers bluetooth updates and has an app. I am not sure head to head which is better. Its matter of choice of aesthetics. Cant go go wrong with either.
