Patch/plug repairs are most often performed using a one-piece repair unit that combines the repair stem and cap (or patch) into one unit. This is commonly known as a combination repair or a patch/plug repair. The purpose of this article is to show you the difference between a safe, permanent repair and a temporary string, plug or patch repair.Īccording to the National Highway Traffic Safety Administration (NHSTA) and the Tire Industry Association (TIA), the only method to properly repair a tire puncture is to fill the injury with a repair stem and back the stem with a repair patch. Luckily there are safe and cost-effective ways to properly repair most tire punctures.


So, you have a flat tire or one that’s leaking air.
