I just went over 3,500 on my back tire and picked up a small brad nail in between the tread (in the grooves) in the middle of the tire. My questions is should I repair this because of it's location in the tire or buy a new one? I know what the manufacture say and also no one will repair it for me either (To many law suites has made everyone shy). In the old days the plug and inner patch was a normal repair. What say you?
