The following are methods for repairing car tires: 1. Plugging with Rubber Strips: Use a specialized awl to insert a glue-coated rubber strip into the puncture, leaving a portion outside. The advantage is that it doesn't require separating the tire from the rim or rebalancing, making the repair quick. The downside is that inserting the awl may enlarge the original hole, potentially causing slow leaks. The quality of the rubber strip also directly affects the repair quality. 2. Cold Patch: Remove the tire, sand the inside of the puncture, apply cold patch glue, let it dry slightly, then apply the cold patch. The advantage is that it's suitable for common punctures and is the most widely used method. The disadvantage is that while the hole is patched from the inside, the outer hole remains, allowing water to seep in and damage the steel belts and fabric layers. It's not suitable for larger holes. If the hole is big, sharp objects like gravel may puncture the patch from the outside. 3. Mushroom Plug: Similar to the cold patch method, but includes inserting a rubber plug through the hole from the inside to the outside, completely sealing the puncture. The advantage is that this combined patch-and-plug method is very reliable. The disadvantage is it's not suitable for small holes. 4. Tire Sealant: A chemical compound designed to automatically seal minor tread punctures. It's an emergency solution for use during travel, but only effective for very small punctures.
