How long does it take for a tire to bulge after scraping the curb?

If a tire hits a pothole at high speed, it will bulge immediately; if the speed is slower or the impact is minor, the cord fabric may not break, and the tire won't bulge right away. Besides hitting potholes or impacts, the following situations can also cause tire bulging: 1. Driving with long-term underinflated tires: Underinflation squeezes the tire's cord fabric, making it prone to fatigue and cord breakage during driving. 2. Parking on uneven surfaces for extended periods: Parking with the tire on the curb can gradually damage the cord fabric, leading to bulging. 3. Wheel rim deformation: A deformed wheel rim can forcefully squeeze the tire, damaging the cord fabric and causing bulging after some time of driving.
The time it takes for a bulge to appear after a tire scrapes against the curb is actually uncertain—it depends on the severity of the scrape and the condition of the tire itself. I’ve personally experienced this situation: one day while driving, I accidentally scraped the curb. At first, it seemed fine, but after driving a few hundred kilometers, I noticed a small bulge on the sidewall. Tires are made of fabric plies and rubber. If the internal structure is damaged during the scrape, the plies can break, allowing air to seep in and form a bulge. A minor scrape might take days to show signs, while a severe one can cause noticeable abnormalities while driving. Such bulges are extremely dangerous—a blowout can easily lead to loss of control, especially at high speeds. That’s why after any curb scrape, I immediately stop to inspect the tire sidewalls, and even if there’s no bulge, I take it to a repair shop for a professional check. Regular maintenance is crucial—never overlook tire conditions to prevent minor issues from escalating. I recommend checking tire pressure and wear regularly and replacing aging tires promptly to significantly reduce the risk of accidents.
