Can a Nail Puncture in the Sidewall of a Tire Be Repaired?
3 Answers
Tire sidewall punctures cannot be repaired and require replacement. In addition to sidewall punctures necessitating tire replacement, the following situations also require immediate tire replacement: 1. The diameter of a puncture hole in the tread exceeds 6 millimeters; 2. Deformation of the bead or tread, rubber corrosion, or tire damage due to underinflation; 3. The tire has been repaired more than four times for punctures. Below are some precautions regarding tire punctures: 1. Whether the nail is in the sidewall or tread, do not remove it immediately. Drive to a nearby repair shop for assistance. Sometimes, removing the nail may not cause immediate air leakage, but it still requires attention. 2. For sidewall punctures, replacement is strongly recommended. The sidewall is the weakest part of the tire, constructed with two layers of rubber and two layers of cord. Passenger car tires for shock absorption do not have steel belts in the sidewalls.
I once encountered a situation where a nail punctured the sidewall of my tire. As a car enthusiast, I must emphasize that safety comes first. A puncture in the tire sidewall absolutely cannot be repaired because the sidewall is very thin, and the internal reinforcement belts can be damaged. After repair, the strength is significantly reduced, making it prone to blowouts under high-speed pressure, which is extremely dangerous. A friend of mine tried repairing a sidewall puncture, and a few days later, the tire burst, nearly causing an accident. I recommend stopping immediately, changing to the spare tire, and going to a professional tire shop as soon as possible for inspection and replacement with a new tire. Don’t try to save money or cut corners. Additionally, regularly checking tire pressure and surface wear can help prevent similar issues—after all, safety is priceless. Although buying a new tire may be expensive, it ensures long-term peace of mind while driving.
Having driven for many years, I also consider saving money when on a tight budget, but repairing a nail puncture on the tire sidewall is not advisable. The sidewall is the most vulnerable part of a tire, with a complex internal structure where repair materials cannot firmly adhere, making it prone to air leaks or ruptures again, which could lead to additional costs for towing and tire replacement. I've heard mechanics share cases where repaired sidewalls blew out on the highway, causing significant losses. It's better to directly invest in new tires, opting for durable brands on discount. Additionally, paying attention to driving habits, such as avoiding curbs, can reduce similar risks, making it more economical and worry-free in the long run.
