- Familiarity: I've used it several times
After less than 800 miles, the rear tire developed three bulges in the tread area, with one being the perfect shape of a rectangle. I have not abused these tires and ran them at 5% less than the max pressure indicated on the sidewalls. There are zero indications of damage from impacts, cuts or other skids. The tread area looks perfect other than the three distinct bulges. I contacted CC and the rep said Conti only warrantied their tires for 60 days, and it happens that I've owned them 85 days. I've emailed Conti but yet to receive a response. If this isn't resolved with a new tire, I'll never purchase another Continental tire, bike, vehicle or otherwise.
