What is the Replacement Cycle for Car Tires?
2 Answers
Car tires should typically be replaced every 5 to 6 years. After reaching a certain age, fine cracks indicating aging may appear on the tires. Minor cracks are generally safe for normal use, but when the tread wears down to a low level, replacement should be considered. Severe wear can compromise driving safety. The functions of tires include: 1. Supporting the entire weight of the vehicle and bearing the load; 2. Transmitting traction and braking torque to ensure adhesion between the wheels and the road surface; 3. Absorbing and reducing vibrations and impacts during driving, preventing excessive vibration and premature damage to vehicle components; 4. Enhancing high-speed performance, reducing driving noise, and ensuring safety, handling stability, comfort, and fuel efficiency.
I've been driving for almost twenty years, and when it comes to tire replacement, don’t delay. Generally, it’s recommended to replace tires every 5-7 years or when the mileage reaches 50,000-80,000 kilometers, but the key lies in regular inspections. Every time I service my car, I check the tread depth—insert a one-yuan coin into the tire grooves. If the coin’s design is still visible, it means the tread is too shallow, below the 1.6mm safety limit, and it’s time to replace them immediately. Tire aging is even more dangerous—if there are cracks on the sidewalls or the rubber has hardened, high-speed driving increases the risk of a blowout. Good driving habits, like avoiding sudden braking and driving on smoother roads, can extend tire life, but don’t exceed 7 years. Tire pressure is also crucial; imbalances lead to uneven wear and shorten the lifespan. In short, safety comes first—regular checks are better than anything else to avoid accidents.
