I agree with Larry Price about the plug/patch repair. I did some research last year, checking several sources such as manufacturers, tire repair sites etc. My surprise was that many said that a plug, i.e sticky rope was probably better than a patch only. The reason was that the hole is still present with a patch only and moisture, debris etc. can get in and damage the repair. I would have to say thought, that I have plugged many tires and can remember only 1 that I had to do over. The rest held for the life of the tire.
