bradvanhorn Posted April 14, 2011 Report Share Posted April 14, 2011 Can anyone cite any credible study, research, data, etc., which substantiates the opinion it is unsafe to use a plug to repair a motorcycle tire? The reason behind this question is one of my co-workers was turned away from motorcycle training, and the reason cited by the instructor was because of a plug in the rear tire. My co-worker bought the tire almost three years ago, and within a few days of purchase he picked up a nail in the meat of the tire, just off center. He had a service department plug the tire, and he has ridden over 1500 miles on the tire since the repair. He has never had a problem with the tire, and was confused as to why this was assessed as unsafe by the instructor. I have since talked to a local service department, Michelin USA corporate (the tire in question is a Michelin Pilot Power), the Rubber Manufacturers Association (oversees tire manufacturers in the U.S.), and the National Highway Traffic Safety Administration, and I have online researched other local/state/national regulations and safety inspection standards, and I can find nothing at all to explain if it is actually safe or unsafe to use a plug to repair a motorcycle tire (in the meat of the tread, not in the sidewall). The local service dept. and Michelin said it was very unsafe and not recommended, but they could offer no explanation why it is so unsafe, except in extremely vague, ambiguous terms. The remaining associations/agencies had no recommendations at all. Frankly I distrust the first two because I believe they are financially motivated ("we can't plug that tire, but we'll happily sell you a new one") and/or they are more concerned about liability lawsuits.
