Should a patch or a mushroom plug be used for repairing a run-flat tire?

[LondynAnn]

If the tire puncture is relatively large, then a mushroom plug is better for repair; if the tire puncture is shallow and small, then a patch is more suitable. Below is an introduction to mushroom plug tire repair: 1. Repair principle: As the name suggests, mushroom plug repair uses a rubber patch shaped like a mushroom. The puncture is located from the inside of the tire, the mushroom stem is threaded through from the inside, the exposed part is trimmed off, and the inner part is secured with special adhesive. The mushroom stem provides an external repair effect, while the mushroom cap serves as an internal repair. 2. Disadvantages: Although mushroom plugs are effective for tire repair, they are not suitable for shallow and small punctures. This is because the mushroom plug requires enlarging the puncture to thread the plug through, achieving both internal and external repair effects. Using a mushroom plug on a shallow and small puncture can actually damage the tire. Therefore, for shallow and small punctures, simply applying a patch on the inside of the tire is sufficient.
