Is it necessary to replace a tire if a nail punctures the tire edge?

It is not mandatory to replace a tire if a nail punctures the tire edge; normal repair is sufficient. Punctures at the edge of a tire are quite common, and as long as it can be professionally repaired, the tire can continue to be used. After a tire is punctured by a nail, the vehicle should not be driven to avoid causing secondary damage to the tire. Situations that require tire replacement include: 1. Tread wear reaching the limit: Car tires have wear indicators in the grooves, typically 1.6 mm for household cars. When the tire wear reaches the limit indicator, the tire should no longer be used; 2. Bulging: If a tire shows bulging, it indicates that the cords at the bulging area have broken. Continued use may lead to a tire blowout, necessitating immediate replacement with a new tire.
I've been driving for over a decade and encountered many tire issues. When a nail punctures the tire edge, you really need to be careful. That area, known as the tire shoulder, undergoes significant bending and pressure during rotation. While a patch might work temporarily, over time it's prone to cracking, leading to air leaks or even blowouts – which can be life-threatening on the road. From my experience, assess the nail's penetration depth. If it's just a surface scratch without air loss, avoid high speeds and slowly drive to a repair shop for inspection. But in most cases, for safety's sake, you'll need to replace the tire. Otherwise, an accident on the highway could cost far more than repair expenses. Remember to check your tires regularly – don't wait until you get a puncture to regret it.
Safety first, I believe that if a tire has a nail puncture near the edge, it should be replaced immediately. Why? Because that area is the most vulnerable part of the tire and undergoes significant stress during turns and maneuvers. While patching might be cheaper, the adhesive patches often don't hold securely. At high speeds, the tire can deform and easily tear, leading to rapid air loss and sudden blowouts, which can cause accidents. My own car nearly had an incident for this exact reason. Check how deep the nail is and whether there's any air leakage. If it's leaking, don't drive to the shop—call for a tow truck or use the spare tire. Although replacing the tire costs money, human life is priceless, and this risk isn't worth taking. Regular maintenance and investing in good-quality tires can save you a lot of trouble.
A nail in the tire edge doesn't necessarily require replacement, but it depends on the situation. If there's no air leakage and the nail puncture is shallow, you can try patching it. Patching is cheaper, while a new tire costs two to three hundred yuan. I've seen some friends save money this way, only to have the tire leak again after a few days, which is quite dangerous. Actually, edge punctures are harder to patch securely, as patches tend to lift. It's best to have it checked at a professional shop where they can perform pressure tests to decide. If there's no air leakage, drive slowly temporarily, but if the tire is old, it's simpler to just replace it. Don't compromise on safety; don't risk big problems to save small money.
