Why Doesn't the Tire Repair Glue Stick?
2 Answers
Because the tire hasn't been sanded, the adhesion is insufficient. Here is relevant information about tire repair: 1. Cold Patching: During cold patching, the tire needs to be removed, the puncture located, and any debris around the puncture cleaned. Then, a special tire repair patch is applied from the inside of the tire to complete the repair. This method is similar to bicycle tire repair, but it requires a specialized tire repair machine and patches. 2. Using a Mushroom Plug: A rubber patch shaped like a mushroom is used. The puncture is located from inside the tire, the mushroom stem is pushed through to the outside, and the exposed part is trimmed off. The inner part is then glued with special adhesive. The mushroom stem provides an external repair effect, while the inner part serves as an internal repair. The mushroom plug method takes longer and is more expensive than other repair methods, but it offers better and more durable results, making it clearly the best tire repair method.
Last time I repaired my own tire, the glue just wouldn't stick properly. After struggling for a long time, I realized the issues were with expired glue and not cleaning the surface properly. Improper storage exposing the glue to high temperatures or humidity can cause it to dry out and become ineffective. The cheap glue I bought had expired, and I didn't notice. There was a lot of dust and grease on the tire surface, making it impossible for the glue to adhere directly. I had to spray it with a special cleaner, wipe it dry, and roughen it up, just like cleaning car windows. Also, the environment was too cold—working in the garage during winter made the glue hard to cure. Applying the glue also requires care; too little or too much won't work. You need to wait until it thickens before pressing the patch firmly for a few minutes. If you can't manage it, for safety's sake, I always recommend going to a repair shop to check the tire's integrity to avoid leaks and accidents. Don't skimp by buying expired glue—stick with reputable brands for guaranteed quality.
