Can a punctured tire be repaired?
2 Answers
Tire punctures can be repaired. Here are some precautions for car tire usage: 1. Bulges: If a tire develops a bulge, it must be replaced immediately to avoid increasing the risk of a blowout. 2. Tire lifespan: Tires are rubber products, and rubber deteriorates over time. Normally, tires installed on a car can last for four years. 3. Regularly check tire pressure: It's important to frequently check the tire pressure during regular use. Tire pressure should neither be too high nor too low. If the pressure is too high, it reduces the contact area between the tire and the ground. If the tire pressure is too low, the tire may experience wave-like deformation during high-speed driving, increasing the risk of a blowout and potentially shortening the tire's lifespan.
I remember whether a punctured tire can be repaired depends mainly on the size and location of the hole. Small holes, like those caused by nails with a diameter less than 6 mm and located in the central tread area, can be fixed using hot or cold patching methods. I've tried it several times, and professionally repaired tires can last for years without issues. However, large holes or those in the sidewall area must never be repaired because the sidewall flexes repeatedly during turns, making patches unreliable and increasing the risk of a blowout, especially at high speeds. Tire repair is inexpensive, costing just a few dozen yuan, whereas a new tire costs several hundred—don’t compromise safety to save a little money. The inspection method is simple: if the tire pressure light comes on due to a puncture, check for slow leaks by applying soapy water to the tread and looking for bubbles to locate the leak. Safety always comes first—when in doubt, it’s better to replace the tire.
