Can tires with small cracks after five years but minimal wear still be used?

Tires with small cracks after five years of use but minimal wear should not continue to be used. Below are specific guidelines for tire replacement: 1. Replacement time depends on conditions: For drivers with good driving habits, tires generally need to be replaced every 3-5 years or after traveling 60,000-80,000 kilometers. If driving conditions are harsh, such as frequently traveling on gravel roads or experiencing frequent traffic jams, sudden braking, or sharp turns, the replacement interval will be shorter. 2. Tire aging period: The primary material of tires is rubber, which undergoes natural aging. This typically manifests as the tires hardening and developing small cracks on the sidewalls. The natural aging period is usually 4-5 years. Tires that have been used for five years should be replaced promptly to avoid the risk of blowouts. 3. Check tire wear: If the tire wear is severe and the tread pattern is level with the wear indicators, the tires should be replaced. Otherwise, braking on wet or slippery roads will be more difficult, increasing the risk of losing control of the vehicle. Additionally, driving on rough surfaces may lead to tire blowouts.
