How long does it take for a tire to bulge after rubbing against a curb?

Generally, bulging occurs when driving quickly over uneven road surfaces, and rubbing against a curb usually does not cause bulging. The following are the types of tire bulging: 1. Crown separation: The "crown" mainly manifests as delamination at the top of the tread surface (referred to as the crown). 2. Bead separation: Mainly occurs in radial truck tires. It primarily shows as separation around the rim. Issues during the bead wire closing process can cause the wire ring to crack and delaminate. The rubber around the bead wire ring may age and delaminate due to high temperatures or problems with the rubber compound itself. 3. Sidewall bulging: Mainly occurs in radial passenger car tires when driving too fast over potholes, curbs, or road debris, causing the rim and road surface to squeeze the tire sidewall, leading to broken sidewall cords and localized bulging.
Once while reversing, I scraped the curb and didn't pay much attention at the time. The next day when I drove, the tire had a huge bulge. This was mainly because the scraping damaged the internal cord layers of the tire, causing uneven air pressure. I learned my lesson and now always stop immediately to check the tire sidewalls for cracks or deformations whenever I hit a curb. In most cases, minor scrapes may not cause immediate bulging, but if the impact is strong enough, broken cords can lead to bulging within just a few dozen kilometers or even minutes. I recommend everyone to drive carefully, avoid getting too close to the roadside, and regularly check tire wear to prevent blowouts on the road.
