What Causes Rear Tire Blowouts?

[DeEsther]

Here are the specific reasons for rear tire blowouts: 1. Traumatic cracking: This type of cracking generally has no regularity in terms of location, shape, or size, and is caused by collisions, compression, or scraping against foreign objects while driving. Some cracks only occur on the surface of the rubber, while others may damage the tire's body cords. In severe cases, it can cause the tire to lose air instantly. If the cracks on the rubber surface are minor, they do not affect the tire's safety and can continue to be used. However, if the cracking reaches the body cords or even damages them, it poses a safety hazard and must be replaced as soon as possible. 2. Aging and cracking: This type of cracking usually occurs in the later stages of tire use, commonly seen on the tire shoulders or lower sidewalls, and sometimes at the bottom of the tread grooves. This is a natural change in the tire rubber due to long-term flexing and heat generation. Driving with consistently low tire pressure can accelerate this process, but it generally does not affect the tire's lifespan or safety performance, and premature replacement is usually unnecessary.
