Why Do Tires Develop Small Cracks After 2 Years?

Why Do Tires Develop Small Cracks After 2 Years? Mostly due to poor maintenance. Here are specific explanations for small cracks appearing on 2-year-old tires: 1. Crazing: If crazing occurs on the tread area, you can determine whether replacement is needed based on the actual severity of the cracks. If it appears on the tire sidewall, especially at the junction between the sidewall and the apex rubber, immediate replacement is essential. 2. Service Life: The effective lifespan of tires is three to four years, but actual replacement mileage may vary depending on driving conditions and frequency. However, tires are ultimately rubber products. Even with the addition of carbon black, they gradually age under environmental influences, and molecular structure changes invisible to the naked eye may occur, affecting tire performance.

I've encountered the issue of small cracks appearing on tires after just two years of use. Tires are made of rubber, which naturally ages, especially when exposed to strong sunlight or high temperatures. UV rays can make the rubber brittle and cause cracks. Additionally, if you frequently drive on rough roads or the tire pressure is insufficient, uneven surface stress can make them more prone to cracking. I must remind you that tire condition directly affects driving safety. Too many small cracks can lead to air leaks or even blowouts, which is extremely dangerous at high speeds. Remember to check your tires regularly, ideally every six months, ensuring the pressure is within the standard range. When parking, choose a shaded spot to avoid prolonged sun exposure, as this can extend their lifespan. Moreover, if the cracks are deep or widespread, don't hesitate—replace the tires immediately. Safety always comes first.

Sigh, seeing cracks on the tires worries me a lot. Only two years and it's already like this? Most likely it's due to rubber aging. Excessive sunlight exposure or parking in high temperatures can accelerate crack formation. As someone who frequently drives long distances, I know this seemingly minor issue can be dangerous. When cracks are too deep, the tire bears uneven pressure, significantly increasing the risk of losing control at high speeds. During inspections, pay attention to whether the tire pressure is too low, as winter contraction and summer expansion can both cause problems. I recommend buying a tire maintenance spray to reduce UV damage. If there are many cracks, it's best to have them assessed at a repair shop. Although replacing tires is costly, it's worth it compared to the losses from an accident. Safe driving truly can't overlook these details.

Speaking of tire cracks, a friend of mine also encountered this issue with his new car after two years. The main cause was rubber aging due to heat exposure. In hot weather, the tire surface dries out and cracks, especially when exposed to prolonged outdoor sunlight. For daily parking, avoid leaving your car under direct sunlight. Check tire pressure weekly to prevent air leaks or excessive wear. Don't panic over minor cracks—first observe their depth. If they're deep, just consult a professional for advice.
