Can plugging a tire with a rubber strip be used long-term?

Plugging a tire with a rubber strip cannot be used long-term. This method involves inserting a rubber strip coated with adhesive into the tire puncture using an awl to stop the leak. Since this repair method requires some grinding and enlarging of the puncture, and its reliability is relatively poor, the puncture typically starts leaking again after 3 to 5 months. The three types of cold tire repairs are rubber strip, patch, and mushroom plug. The mushroom plug method not only offers the stability and reliability of patch repairs but also provides the anti-corrosion benefits of rubber strip repairs. Therefore, if conditions permit, it is recommended to use the mushroom plug method for tire repair. Since replacing a tire alters the mass balance between the tire and the rim, an unbalanced wheel can cause severe vibrations during high-speed rotation, affecting driving safety. Thus, it is essential to perform tire dynamic balancing after replacing a tire.
I remember my first flat tire was on a rural road with no repair shops around, so I used a plug as an emergency fix. It was indeed convenient—just insert it, add some air, and drive off. But it's not a long-term solution because it only seals the surface hole without addressing internal structural damage like broken steel belts or delamination. Over time, slow leaks can occur, leading to unstable tire pressure that affects handling and increases the risk of a blowout at high speeds. I thought I was saving trouble, but a few days after the plug, the tire went flat again and consumed more fuel. Only a professional internal patch with vulcanized rubber can truly seal the damage, making the tire durable for thousands more miles. Tires are the lifeline of a car—for safety, plugs are just a temporary patch; get a proper repair as soon as possible.
