... it’s about how the repair was done.
Both plugs and patches can be effective tire repair solutions.
Patches are generally considered better because they are done from the inside of the tire by a pro and are only done when the pro considers it safe.
But a plug can be just as good as long as it fixes a small puncture in the tread of the tire ( never when near or on the sidewall) and that had not compromised the structural integrity of the tire.
A small hole made by a nail or screw in the middle of the tread is generally able to be plugged without compromising safety.
The tire carcass is made up of layers of crisscrossed mesh and fibers which are then covered in rubber. A small nail will generally slide through the mesh without ripping it.
But even when using the provided reaming tool the amount of cut fibers do not adversely affect the tire.
The plug is inserted from the outside with the tire mounted on the rim and as soon as the tire starts rotating it forms a mushroom head air seal on the inside which can last for the remainder of the tire’s life.
I have plugged a few of my tires and have then taken them on the track without fear. I’ve never had an issue.
Nevertheless I would be uncomfortable putting a plugged tire on my car that I don’t know who fixed it and under what conditions.
I’m sure others will disagree.
Happy Boxstering
