How Long Should Car Tires Be Used Before Replacement?
3 Answers
Usage time should not exceed 5 years; mileage under comprehensive road conditions should not exceed 60,000 kilometers. Here is more information about tires: 1. Extending Tire Lifespan: Avoid turning the steering wheel while stationary, steer clear of bumpy roads, and maintain proper tire pressure. 2. Brief Description: Car tires are one of the crucial components of a vehicle, directly contacting the road surface. Together with the car suspension, they help absorb shocks during driving, ensuring good ride comfort and smooth driving performance. They also ensure excellent adhesion between the wheels and the road surface, improve the vehicle's traction, braking, and off-road capabilities, and bear the weight of the car. The important role tires play in vehicles is increasingly being recognized.
How long can tires actually last? There's really no standard answer to this question. Having driven for over 20 years, I've seen tires worn out at just 40,000 kilometers, and others still usable after 80,000 kilometers. The key lies in driving habits: those who frequently drive on highways will wear tires faster than city commuters, while aggressive braking and acceleration are the most tire-damaging behaviors. Tire pressure is a silent killer – chronically underinflated tires wear out 30% faster, especially on the shoulders. Remember to check tread depth with a coin during seasonal changes: national standards require at least 1.6mm, but anything below 3mm becomes slippery in rain. If you spot sidewall bulges, replace immediately – they're like time bombs waiting to blow.
Replaced all four tires after just over 20,000 kilometers, it hurt so much I couldn't help but grimace. The mechanic taught me three self-inspection tips: First, check the wear indicators—there are small raised bumps in the tire grooves, and if they're worn down, it's time to replace them. Second, look for aging cracks, especially those fine spiderweb-like lines on the sidewalls, which indicate the rubber is deteriorating. Third, note the manufacturing date—the last four digits after the 'DOT' letters on the tire sidewall mark its 'birthday,' and if it's over five years old, be cautious even if the tread depth is good. It's recommended to clean out small stones stuck in the treads when checking tire pressure each quarter—those things make a 'click-clack' noise while driving and can damage the rubber.
