Tires can typically run for 60,000 to 80,000 kilometers under normal usage, but the exact distance depends on local road conditions and specific usage. The replacement criteria and maintenance methods for tires are as follows: Tire Replacement Criteria: New tires have wear indicators in their grooves. Once these indicators become visible, the tires should be replaced as soon as possible. Overused tires can lead to dangerous skidding, resulting in poor braking or even rollovers. If steel cords are exposed or the rubber is cracked during use, the tires are no longer safe and must be replaced immediately. Additionally, bulges or dents also require immediate replacement. Tire Maintenance Methods: Tires naturally age over time with use. To prolong their lifespan, avoid exposure to acidic or alkaline substances, strictly prohibit overloading or speeding, regularly check tire inflation pressure, and avoid sharp-angle squeezing, driving over roadbeds, or curbs.

Seeing my neighbor just changed tires reminded me that tire lifespan isn't just about mileage. My current set has run over 70,000 km without replacement - the key is checking rubber aging and wear indicators. Tires on rough roads may crack in three years, while highway-driven ones can last five. Unstable tire pressure causes uneven wear (learned that the hard way, so I check monthly). Those little raised bars in tread grooves are safety indicators - worn-out tires become dangerously slippery in rain. Remember: rotating tires extends life, as front tires wear much faster than rears.

During my last long-distance trip, I noticed severe steering wheel vibration, which turned out to be caused by uneven tire wear. From experience, household tires lasting 80,000 kilometers is considered good performance, but road conditions have a huge impact. My tires developed small cracks on the sidewalls after just 40,000 kilometers of driving on suburban gravel roads, while a friend's commuting tires in the city remained usable after six years. Driving habits matter greatly - aggressive acceleration and sharp steering wheel turns wear tires exceptionally fast. Regularly check tread depth by inserting a coin vertically into the groove; if one-third of the national emblem is visible, it's time to consider replacement. Don't hesitate to replace tires that have been patched more than three times - earlier replacement means earlier safety.

Just heard from the technician at the 4S shop that 60,000 kilometers is the baseline for normal city use. However, rubber has a five-year shelf life, and aged tires can harden and slip. I've seen cars parked in garages for five years—the treads look new but are full of cracks. Little-known fact: Chronic underinflation can halve tire lifespan. Vehicles frequently carrying heavy loads in the back should pay extra attention to rear tire wear. I always keep a tire pressure gauge in my car to maintain the manufacturer's specified values. When buying new tires, remember to check the four-digit DOT code to calculate the production year.
