Wondering if that quick “plug” tire repair is still safe to drive on? Here’s how to repair a flat tire:
Remove the tire from the wheel.
Inspect the tire inside and outside. The tire may be repaired when the puncture:
Is 1/4 inch or smaller
Is located on the tread
Repair the tread with a plug, and repair the lining with a patch.
Repairs cannot overlap.
Never repair a large hole or one that’s in the sidewall. It isn’t safe and could lead to a dangerous blowout.
A plug by itself, or a patch by itself, is not acceptable. But a safer tire repair, done to the RMA standards, can give you thousands of miles more use from your tire.
