What to Do When a Nail Punctures the Tire Tread Without Causing Air Leak?
2 Answers
Tire punctured by a nail without air leakage should be driven at low speed to the nearest repair shop for inspection. Below are detailed instructions: 1. A punctured tire without air leakage must not be left untreated, as it may lead to a tire blowout accident, posing significant hazards. 2. It is important to note that if a tire is punctured by a nail, the nail should not be pulled out immediately, as this could cause severe air leakage, rendering the tire unable to continue driving. If the tire pressure is high, pulling out the nail might cause a blowout, which is extremely dangerous. 3. Most car tires on the market today are tubeless tires. When a tubeless tire is punctured by a nail, the air leaks very slowly, possibly unnoticeable. However, once the nail is removed, air leakage will occur, necessitating immediate repair. The best method for repairing such a puncture is using a mushroom plug, which involves inserting a mushroom-shaped rubber strip from the inside of the tire to the outside, completely sealing the puncture. The exposed part is then trimmed off, and the inner part is secured with special adhesive.
A while ago, my car had this unfortunate incident—a large nail got stuck in the tire tread without any air leakage, appearing fine but actually posing a serious risk. When I noticed it, my heart skipped a beat, so I immediately asked my mechanic friend. He warned me never to pull the nail out myself because it might be sealing the hole by wedging into the tire surface. If removed, it could cause instant air loss or internal damage, which would be disastrous. He advised me to find a safe spot to stop and inspect it first. If the tire pressure was normal, I should drive slowly to the nearest tire shop, avoiding highways to minimize the risk of a blowout. A professional technician would use tools to remove the nail, test for actual leaks, and then decide whether to patch or replace the tire. He also reminded me to make it a habit to glance at the tires regularly while driving and check tire pressure monthly to avoid major troubles.
