Why Are Screws Always the Ones Puncturing Tires?
1 Answers
The threads of screws can easily embed into tires when run over. Common tire repair methods are as follows: 1. Traditional Plug Method (External Repair): This is a more primitive method. The principle involves using a sharp tool like an awl to enlarge the puncture hole, then inserting a rubber strip coated with adhesive into the hole. It's simple, very low-cost, and quick, requiring no separation of the tire from the rim or wheel balancing. The downside is obvious: enlarging the hole with an awl increases the damaged area, and this method isn't very durable, often leading to air leaks. (This method is not recommended) 2. Patch Repair (Internal Repair): This is the most common method, used by most tire repair shops. The tire is separated from the rim, the damaged area inside the tire is sanded to help the adhesive bond better, then the debris is cleaned off. Special tire repair adhesive is applied to the damaged area and its surroundings, a patch is pressed firmly onto the spot, and another layer of adhesive is applied to complete the repair. 3. Mushroom Plug Repair (Internal Repair): The mushroom plug is currently the most advanced tire repair method, also an internal repair. It requires separating the tire from the rim, and wheel balancing is necessary after repair. The difference between the mushroom plug and the patch method is that the mushroom plug can effectively fill the gaps in the puncture hole, preventing further damage to the affected area.
