Can tires from 2016 still be used in 2021?

Tires generally have a lifespan of 5-6 years. Tires from 2016 can still be used for about a year in 2021, provided that the tire quality is excellent. Ensure tire balance: After use, tires may become unbalanced, causing steering wheel and chassis vibrations, and may even lead to steering failure. In such cases, it is necessary to take the car to a repair shop for balance correction as soon as possible. Dealing with a flat tire in an emergency: If a flat tire occurs suddenly while driving, stop the car immediately, turn on the hazard warning lights, and change the tire. After stopping, the parking brake must be engaged, and the wheels must be secured. Loosen the nuts on the flat tire, then use a jack to lift the vehicle. Remove the nuts and the flat tire, replace it with the spare tire, lower the jack, tighten the nuts, and you can continue driving.

Last time I helped my friend check his old car, the tires were manufactured in the 15th week of 2016, and there were already cracks on the sidewalls. After more than five years, the rubber starts to age, so even if there's plenty of tread left, it's time to replace them. The small triangle mark on the side of the tire points to the wear indicator block. If you insert a 1-yuan coin into the tread groove and can see the anti-counterfeiting line on the edge of the coin, the tread is too thin. Especially for those who drive on highways, be extra cautious—old tires are particularly prone to blowouts in the summer heat. I've seen several people changing tires at service areas, all due to old tires. Quickly check the aging level—don't wait until an accident happens to regret it.

The original tires on my grocery-getter were also from 2016 and were replaced last year. Actually, tire lifespan depends not just on age but also on actual wear. Avoid constant sun exposure when parking, check tire pressure regularly, and the tires can last an extra six months. However, I recommend using your phone's flashlight to inspect the tread—if you see fine cracks like a spider web, it means the rubber has hardened and it's time to consider a replacement. Especially the front tires are crucial, as a blowout can affect steering. Tires parked underground versus outdoors can age at twice the rate. The safest approach is to have a mechanic measure them with calipers regularly.

A colleague's old Accord also encountered this issue. The tires, which had been in use for 5 years since leaving the factory, had traveled less than 20,000 kilometers. Professional testing revealed that the rubber hardness exceeded the standard, and the wet grip was only 70% of that of a new tire. Tires are most afraid of long-term parking and extended use. Our fleet management requires mandatory replacement every five years, regardless of wear. After all, the cost of a tire is much cheaper than repairing an accident vehicle. Safety comes first.

I remember the year I first started driving, I was terrified when my overdue tires slipped while cornering. Tire performance plummets in the sixth year. Here's how to check the production date: for example, if there's a number like 3716 in the circle on the tire sidewall, it means the tire was produced in the 37th week of 2016. If you frequently drive on construction sites or rough roads, you should replace them even earlier. Tires that have been patched more than twice shouldn't be used until the fifth year either, as the tread structure is already damaged. Don't forget to do wheel balancing when changing tires, otherwise the steering wheel may vibrate.

Last week, my neighbor's car had a flat tire, which was due to the six-year-old tires. Once rubber passes its expiration date, it becomes brittle, just like an old rubber band. It's best to replace all four tires at the same time, or at least ensure both tires on the same axle are a pair. Winter tires have a shorter lifespan due to their different rubber compound. Rear-wheel-drive cars experience faster wear on the rear tires, so regular rotation is necessary. Tire shops often offer a small rebate for recycling old tires. A special reminder for car modification enthusiasts: wide and low-profile tires are more prone to sidewall cracking, so their service life should be reduced accordingly.
