How to Repair a Car Tire?
2 Answers
Car tire repair methods: 1. Plugging with rubber strips: Use a specialized awl to insert a glue-coated rubber strip into the damaged area of the tire, leaving a portion outside; 2. Cold patch: Remove the tire, sand the inner side of the damaged area, apply cold patch adhesive, let it dry slightly, then apply the cold patch; 3. Mushroom plug: Similar to the cold patch method, but while applying the patch, a rubber plug is inserted from the inside through to the outside of the tire, completely sealing the hole; 4. Tire sealant: A chemical agent used to automatically seal leaks in car tires. Tire sealant can only automatically repair minor tread punctures and is an emergency method during travel.
I've experienced tire repairs several times. First, park the car on level ground, remove the wheel, and locate the puncture. Use specialized tools to pull out the nail, then roughen the inner surface of the puncture with a rotary rasp to create a coarse rubber surface. Apply vulcanizing glue and let it dry for half a minute, then press a rubber patch firmly with a roller. Finally, apply sealant to the inner tire wall, inflate to standard pressure, and check for leaks. Remember to perform wheel balancing after repair—otherwise, you may feel steering wheel vibrations at high speeds. Sidewall punctures or holes larger than 6mm cannot be repaired—safety comes first. Regularly check the tire pressure of repaired tires, and avoid long-term use on drive wheels if possible.
