Tire plugs are a convenient method of salvaging a flat tire for further use. These plugs are regularly used, provided that the puncture is along the width of the tire. According to the Florida statutes on motor vehicles, there is no specific law on the books regarding the use of tire plugs. However, Florida does adhere to the U.S. Department of Transportation's guidelines on tire safety.
Whether your tire can be fixed by a plug or not depends greatly on the size and location of the puncture. If the puncture is located on the side wall of the tire, or bordering it, then the tire cannot be repaired. Additionally, if the puncture is too large for a plug to fit--for instance, a gash across the tire--then the tire must be replaced.
To properly fix a tire with a plug, the tire must be removed from the rim and thoroughly inspected for additional damage. The puncture must then have a plug installed and a patch applied--internally--to the area surrounding the puncture.
After your tire has been repaired with a plug, pay special attention to the tires performance--particularly its ability to maintain the proper pressure. If you begin to lose pressure, have the tire reinspected and, if necessary, replace it.
