Can tires with small cracks on the sidewall still be used?
2 Answers
Tires with small cracks on the sidewall cannot be used, as small cracks indicate that the tire has been used for too long or improperly maintained, leading to issues. The functions of tires are: 1. Transmitting driving force, braking force, and steering force to enable vehicle operation; 2. Supporting vehicle loads; 3. Reducing and absorbing vibrations and impacts during driving to avoid severe vibrations damaging vehicle components. Tire maintenance methods include: 1. Regularly removing stones stuck in tire treads; 2. Minimizing exposure to direct sunlight; 3. Timely checking tire pressure; 4. Paying attention to suspension maintenance; 5. Periodically inspecting front wheel alignment; 6. Adopting careful driving habits, such as choosing smooth road surfaces and avoiding objects that may puncture or scratch tires, as well as chemical spills that could corrode tires.
Small cracks on the tire sidewall are no trivial matter, and I often remind my friends to pay close attention. The sidewall is the weakest part of the tire's structure. Even if the cracks appear shallow, the repeated deformation during high-speed driving can cause them to deepen suddenly, leading to a blowout. This risk is especially heightened in summer when high road temperatures accelerate rubber degradation. If the sidewall also shows bulging, don't hesitate—replace the tire immediately. When inspecting, use your finger to gauge the depth of the cracks; if they exceed 1 millimeter, act promptly. Tires typically last about five years, and visible cracks indicate rubber aging—never take chances.
