How Many Years Must Tires Be Replaced?

Tires do not have a fixed replacement time; it depends on their usage. Under normal conditions, tires generally need to be replaced after 4-5 years or 60,000-80,000 kilometers. Once this time limit is reached, the rubber begins to age, increasing the risk of damage and blowouts if continued to be used. Cracks: If many small cracks appear on the tire surface, which typically occur after about three years of use, regular inspections should be conducted to monitor any changes in the cracks. If the cracks become too long, too deep, or appear on the tire sidewall, the tire should be replaced. Wear Indicators: Check the tire wear indicators. Each tire is equipped with wear indicators; generally, passenger car tires have a wear indicator height of 1.6 millimeters, while load-bearing tires have a wear indicator height of 2.4 millimeters. When the wear indicators become flush with the tread, it indicates severe tire wear, and the tire should be replaced. Bulges: If a bulge appears on the tire, it is recommended to replace the tire immediately, as continuing to drive with it significantly increases the risk of a blowout.

Generally, tires need to be replaced every five or six years. Even if they look fine on the surface, they are made of rubber and will age over time, becoming prone to cracking and hardening, which increases the risk of a blowout. Having driven for over a decade, I often see friends' tires suddenly blow out on the highway because they haven't been replaced for too long—it's really scary. So, I recommend getting them checked after six years, regardless of mileage. If you don't drive much, say only a few thousand kilometers a year, you should still check the date code to determine the production time, not just rely on mileage. Additionally, storage conditions matter—keeping them in a cool, dry garage can extend their lifespan, but never use them beyond their expiration date. Safety comes first, after all.

Fellow car enthusiasts, how often to change tires depends on the actual situation, not necessarily a fixed number of years. I often drive long distances, and I need to replace my tires after accumulating 50,000 kilometers because severe tire wear affects grip, especially making it prone to slipping in rainy weather. Checking the tread depth is crucial; if it's less than 1.6 millimeters, it's time to take action. The tire production date is marked on the side, so be careful not to buy overstocked tires when purchasing new ones. Regular tire rotation and balancing maintenance can help extend their lifespan, so don't delay too long just to save money. A sudden blowout on the highway is the most dangerous—I've witnessed accidents firsthand. Timely replacement is about peace of mind and saving lives.

Don't just focus on the age when changing tires. I recommend checking and replacing them every three to five years. Daily driving causes significant wear, especially with frequent city commuting and short trips that involve more stops and braking, which accelerates tread wear. If you drive a lot on highways, the high-speed operation makes tires more prone to heat aging. I check tire pressure and tread patterns weekly, using a small coin to measure depth—replace them if insufficient. Storing tires under direct sunlight speeds up cracking, so a garage is ideal. Don't wait for the warning light to act; addressing minor issues promptly can prevent major problems. Budget-wise, investing in genuine brand tires is more durable than off-brands. Safety is no small matter—develop a habit of regular maintenance.
