Will a Scratched Tire Burst?

A thin layer being scraped off is not a problem. As long as there are no bulges or cracks on the tire surface, there is no major issue, and it is unlikely to burst. Signs of tire aging: If there are numerous small cracks at the bottom of the tread grooves or the tire sidewalls that are close to damaging the tire body, the tire should be replaced immediately, regardless of how long it has been used or how much it has worn. Tire tread groove depth reaches or falls below 1.6 millimeters: There are indicator marks in the longitudinal grooves of the tire tread showing this depth. The tire must be replaced because its drainage capacity has significantly decreased, making driving on wet surfaces more dangerous.
I've been driving for over 30 years and have seen plenty of tire issues. If a small chunk is scraped off the tire, will it cause a blowout? It depends on the severity of the damage. Generally speaking, if only a small piece of the tread surface is scraped off and it's not too deep, it may not immediately cause a blowout – you can still manage to drive, but the risk increases. However, if the sidewall is damaged or the cords are exposed, the chance of a blowout is much higher, and you should replace it immediately. I remember one time when I had a sidewall scrape on the highway – I pulled over right away and called for help. So, I recommend checking the damage immediately: feel the depth with your hand. If cords are exposed or there's air leakage, don't drive – find a repair shop. Otherwise, drive slowly to a professional shop for evaluation. Regular tire maintenance can prevent such problems – check tire pressure and tread depth regularly.
I'm particularly concerned about safety, and my car had a similar issue last time. If a chunk is scraped off the tire, there is a risk of a blowout, but it may not happen immediately. The key factor is the location: the tread is thick, so minor damage can still hold up; the sidewall is thin, and a scrape there can easily lead to a blowout. My advice is not to panic, but first pull over safely to inspect the damage: check the depth of the scrape. If you can see light through it or notice a bulge, immediately change to the spare tire or seek help. If it doesn’t look serious, drive slowly to a repair shop. Tires are cheap, but safety is priceless—don’t take risks to save trouble. Also, rotating your tires regularly can extend their lifespan.
