First, it’s important to understand whether your tire needs a patch, plug, or to be replaced completely.
A tire plug is a sticky, expandable substance that gets stuffed in a hole in the tire from the outside and is wedged in until the air stops leaking out. The plug should easily stay intact well enough to re-inflate the tire and get safely to a repair shop.
Secondly, how long does a patch last in a tire?
On average, tire experts predict that a proper plug and patch can last from seven to ten years. Although tire patches can last a long time, a tire should never be patched more than once. It can negatively affect the speed rating and potentially cause blowouts.
Whenever your tire becomes punctured and requires a repair, consult your tire service center and let them determine what type of repair is needed and what is best for the life of your tires.
