Tires have a maximum lifespan of 6-8 years. Generally, it is recommended to use them for three to five years, with a mileage of 60,000 to 80,000 kilometers, and then replace them after inspection based on the mileage or wear level of the tires. The following five habits can extend the life of tires: 1. Develop the habit of checking tire pressure regularly: Air pressure is key to extending tire life. If the tire pressure frequently exceeds 20% of the normal pressure, the tire's lifespan will decrease by 10%; if it frequently falls below 30% of the normal pressure, the tire's lifespan will decrease by 52%. 2. Maintain consistent tire pressure: Tire pressure is the life of the tire. If the pressure is too low, the tire body deformation increases, and cracks are prone to appear on the tire side, leading to excessive heat generation, which accelerates rubber aging, fatigue of the cord layer, and cord breakage. 3. Regularly remove foreign objects from the tires: When driving on the road, small stones often get stuck in the tread grooves of the tires. If these small stones are not removed in time, they can puncture the tire over time, causing air leakage or a blowout. 4. Adopt scientifically sound driving habits: When driving on roads with significant camber, try to stay in the center to avoid or reduce the shift in the vehicle's center of gravity, thereby reducing uneven tire wear caused by increased load on one side. 5. Maintain accurate alignment for the front and rear wheels: Front wheel alignment greatly affects tire lifespan, with toe-in and camber being the main factors. Camber mainly accelerates wear on the tire shoulders (i.e., uneven wear), while toe-in mainly accelerates wear on the inner and outer sides of the tire.

I've been repairing cars for over 20 years, and the maximum lifespan of tires is generally around 10 years. Beyond that, it becomes unsafe. Rubber materials age and oxidize, and even if the tread is still deep, the tires can become brittle and lose elasticity over time. Factors affecting lifespan include UV exposure, high-temperature environments, prolonged parking without use, and poor driving habits. The production date is indicated by the last four digits of the DOT code on the tire sidewall, showing the year and week number. For example, 2118 means the tire was produced in the 18th week of 2018. It's recommended to have tires inspected by a professional shop every 5 years. Aged tires have poor grip, are prone to slipping in rainy conditions, and can easily blow out at high speeds—safety first!

I've been driving for over 30 years on all kinds of road conditions, and my tires typically last 6-8 years, with the longest being 10 years. Once, I had tires on my car that hadn't been changed for over 8 years, and they blew out on the highway, nearly causing an accident—the reason was rubber aging rather than heavy wear. For daily storage, avoid direct sunlight and damp places, as summer heat can accelerate deterioration; don't park with one side flattened for long periods, and check tire pressure regularly for even wear; before trips, inspect sidewalls for cracks or bulges. Saving money on old tires isn't worth risking your life, so I make it a habit to have a technician evaluate them every 30,000 kilometers or 2 years.

As a novice driver, understanding tire lifespan is crucial. Typically, it's 5-10 years at most, depending on driving frequency and road conditions. If tires exceed 5 years, I'd check for cracks or deformities on the sidewalls, and replace them if tread wear is uneven. The production date can be found in the last four digits of the DOT code—the first two digits indicate the year, and the last two represent the week number. Remember to maintain them within the safe period to extend usage slightly, but don't push it to the point of risking a blowout—my friend had an incident because of this.
