Should tires be replaced after seven years and 30,000 kilometers?
2 Answers
Tires that have been used for seven years and 30,000 kilometers need to be replaced. Tire replacement cycle: Generally, the tire replacement cycle is around 5 years or 50,000 kilometers. The shelf life of rubber is typically about five years. If there are no obvious cracks or signs of aging on the tire surface, you can check the distance between the wear indicators in the main tread grooves and the tread wear layer. If the wear indicators are almost level with the tread wear layer, the tires should be replaced. Reasons for replacement: Rubber gradually ages over time, and most tires will start to show signs of aging and cracking after about 4 years. Tires are closely related to safety, so replacement is recommended.
As a driver who frequently takes long-distance trips, I remember the last time I changed my tires was under similar circumstances—after seven years, the mileage had just exceeded 30,000 kilometers. At that time, the tread wear wasn’t obvious, but there were many fine cracks on the sidewalls, especially prone to hardening under high summer temperatures. Aged rubber loses elasticity, leading to longer braking distances and a significantly higher risk of skidding on wet roads. After replacing the tires, I immediately noticed much more stable handling, reducing the likelihood of accidents. I recommend checking the sidewalls for cracks and ensuring the tread depth is no shallower than 1.6 mm. If you spot issues or feel noticeably bumpy rides, replace them promptly—safe driving is the top priority, and it’s not worth cutting corners to let problems accumulate.
