I noticed it the previous week but since then it's gotten bigger. Any ideas on what caused it? I'm thinking a pothole, seems logical. Oh and it's on the sidewall, it's really big considering I have OEM ninja star rims and factory spec tires.

Anyways, how longer should I drive on it before it goes out on me? I have Kelly Charger Plus tires. Pretty good tires with a nice aggressive tread to it.

TIA
Peace

 

That happened to a Nitto 450 of mine. Looked like a golfball. I finally got it replaced after driving with it like that for a long time.
