More problems with Avon? I've had two Distanza front tires fail on me in 3,000 miles total. Where the little injection tits are located on the center line of the tread, the rubber cracks open in about a 1/4" circle, and then after a few more miles the little buggers commence to rip off the tire leaving little gouges in the tread. Anybody else. the production code is 4100.
