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.
