Can a Tire Punctured by a Screw Be Repaired?
2 Answers
Actions to take after a tire is punctured by a screw: 1. If the puncture is on the tire's tread (the part that contacts the ground), the situation is not too severe. You can have it repaired and continue driving, including on highways. The repaired tire will have the same lifespan as other tires and won't be restricted from highway use due to the repair. 2. If the puncture is on the tire's sidewall, the situation is less optimistic. The sidewall is the most vulnerable part of the tire. After repair, if the tire pressure is insufficient, high-speed driving can generate significant pressure. Prolonged driving may cause the tire to overheat, increasing the risk of a blowout. The following situations require immediate tire replacement: 1. The diameter of the puncture hole on the tread exceeds 6 millimeters. 2. Deformation of the bead or tread, rubber corrosion, or damage caused by driving with insufficient air pressure. 3. The tire has been repaired more than four times.
I've been driving for decades and have seen many cases of tires being punctured by screws. Generally, they can be repaired, but it depends on the location and size of the hole. If the hole is small and in the middle of the tread, with a diameter not exceeding 5-6 millimeters, it's usually fine to repair it. I once had a tire with a small screw puncture that a mechanic fixed using a hot patch, and it's still running well today. However, if the hole is too large or located on the sidewall, it's better not to take chances—just replace the tire for safety. There are several repair methods, with hot patches and plug patches being the most reliable. It's best to have a professional handle it rather than attempting a DIY fix. If this happens on the road, don't pull the screw out immediately; drive slowly to a repair shop and check the tire pressure. Regular tire maintenance can help reduce such issues. In short, based on experience, just be cautious and you'll be fine.
