I rode the Blueridge Parkway last week. On my way back to Atlanta on I-77 I started feeling a vibration that seemed to be in the front tire. I stopped and looked but everything looked ok. I started again but it seemed to be getting worse. I stopped again and noticed a bulge in the middle of the front tire. This was about 70 miles north of Charlotte kind of in the middle of nowhere. Luckily I found a shop with the size i needed about 20 miles away in Wilksboro. I limped in there and they were great. Stayed open past their normal closing time and got me back on the road in a little over an hour. For anyone in that area, Payne Power Equipment is a Suzuki dealer and they are good people. The tire was a Dunlop Roadsmart with about 8K miles on it. It was not half worn out but the tread was separating. I have never seen this before in over 40 years of riding. They showed me the tire after ther got it off and there was about a 10 inch long bulge on the inside as well. This was my first Roadsmart. I liked the way it handled but am a little gun-shy about getting another one. They installed a Metzeler(only one in my size) and it feels good so far.
