Can new tires still be used after 8 years of storage?
2 Answers
New tires that have been stored for 8 years can no longer be used. Although the tires may appear new externally after 8 years, they have already undergone aging and cannot meet the normal usage requirements of motor vehicles. It is necessary to replace the vehicle tires; otherwise, it will affect the driving safety of the motor vehicle. Automobile tire lifespan: The service life of tires is generally around 2-3 years or 60,000-100,000 kilometers. Chinese regulations stipulate that tires must be replaced when the tread wear reaches 1.6mm. Vehicle tire replacement cycle: The replacement time for motor vehicle tires is approximately every three years or 40,000 kilometers. Regular and timely replacement of motor vehicle tires helps enhance driving safety. Vehicle tires are the only components in contact with the ground and are crucial for the driving safety of motor vehicles. Their maintenance should never be neglected. Precautions for using automobile tires: When using motor vehicle tires, it is essential to regularly check whether the tires are in normal condition, ensure they can be used normally, inspect for any damage, and verify that the tire pressure is normal to avoid affecting the normal operation of the motor vehicle. Especially before high-speed driving, it is imperative to confirm that the tires are in good condition.
As a seasoned driver with decades of experience, I can confidently say that tires that have been stored for too long are simply not safe to use. My personal experience serves as a cautionary tale: once, I tried to save money by using a spare tire that had been sitting for 7 years, and it nearly caused an accident on a wet road. Even brand new tires, if stored for 8 years without being mounted, will have rubber that has aged and become brittle, losing its elasticity and grip. Over time, exposure to sunlight and temperature fluctuations can cause cracks to form on the tread or sidewalls—sometimes invisible to the naked eye—but they significantly increase braking distance and the risk of skidding in rainy conditions. Rubber has a shelf life, typically 5-6 years, after which replacement is necessary. An 8-year-old tire is definitely past its prime. Don’t gamble with safety to save a few hundred bucks; safety should always come first. I recommend checking the DOT code on your tires for the manufacturing date. If the tires feel stiff or show cracks, discard them immediately. Spending money on new tires is a small price compared to repair costs or the consequences of an accident.
