What is the replacement cycle for car tires?
2 Answers
Car tires should be replaced every 3 to 5 years or after driving 40,000 to 60,000 kilometers. After 2 to 3 years of use, small cracks will gradually appear on the sidewalls of the tires, and they should be replaced promptly if such cracks are found. The functions of tires are: 1. To transmit driving force, braking force, and steering force for vehicle operation; 2. To support the vehicle load; 3. To reduce and absorb vibrations and impacts during driving, avoiding severe vibrations that could damage car components. Tire maintenance methods include: 1. Regularly removing stones stuck in the tire treads; 2. Minimizing exposure to direct sunlight; 3. Promptly checking tire pressure; 4. Paying attention to suspension maintenance; 5. Regularly inspecting front wheel alignment; 6. Adopting careful driving habits, choosing smooth road surfaces, avoiding objects that could puncture or scratch the tires, and steering clear of chemical spills that could corrode the tires.
Having driven hundreds of thousands of kilometers, I've learned that tire replacement shouldn't follow rigid time-based rules – it depends on actual wear and aging. When tread depth falls below 1.6mm, wet-road traction deteriorates significantly, increasing skid risks and requiring immediate replacement. Tires older than six years develop hardened, cracked rubber and need renewal even with intact treads. I recommend quarterly checks: insert a coin into grooves – if the head shows, wear is critical, or inspect sidewalls for bulges/cracks. Generally consider replacement after 40,000km, but driving habits matter – city driving may extend lifespan while highway hard-braking accelerates wear. Safety is paramount – address any abnormalities promptly to avoid dramatically increased accident risks.
