How to Determine if Tires Need Replacement?
2 Answers
Tire replacement can be determined based on the following conditions: 1. The tire tread is close to the wear indicator. During daily driving, tires may hit curbs or be punctured by foreign objects, causing damage such as bulges or cracks. If the tire tread is damaged with bulges, there is a risk of sudden blowout while driving. When bulges are detected, immediate tire replacement is necessary to avoid blowout hazards. 2. Tires develop bulges or cracks. During daily driving, tires may hit curbs or be punctured by foreign objects, causing damage such as bulges or cracks. If the tire tread is damaged with bulges, there is a risk of sudden blowout while driving. When bulges are detected, immediate tire replacement is necessary to avoid blowout hazards. 3. Tires reach their service life. The typical service life for passenger car tires is around five years. Even with good road conditions, tires will age over time, primarily showing cracks, surface hardening, and loss of elasticity. Continued use may lead to tread deformation and blowout risks, requiring prompt tire replacement.
Honestly, judging whether tires need replacement mainly depends on wear level and safety risks. My most commonly used method is tread depth inspection – insert a one-yuan coin into the tire grooves; if the national emblem becomes visible, the depth is below the legal minimum of 1.6mm, and they absolutely must be replaced. Another DIY test is feeling the wear indicators with your fingers – if the blocks are completely flat, the tire is done for. Cracks in the tires are also a warning sign, especially in rainy weather when old tires are prone to skidding. I once hit a curb due to negligence. Additionally, pay attention to the tire's manufacturing date marked by four digits on the sidewall, like 2223 indicating the 22nd week of 2023. Rubber older than five years tends to become brittle. In short, spending two minutes each month to check can prevent costly accidents.
