Lost a tire on the way home from work tonight due to a lane splitting motorcycle. Moving at about 70, on a gentle curve, came up on a retread covering the narrow shoulder and sticking about 3 feet into my lane. I went to swerve around it, had plenty of room in my lane, until a bike cut between me and the guy next to me. I had to move back over to keep from hitting him and hit the piece of tread dead on. Popped my tire. Right on the shoulder of the tire. Can't patch it. Bought a new pair of tires. Yay.
