Can new tires still be used after being stored for 8 years?
2 Answers
Tires stored for eight years cannot be used. Tires have a certain lifespan, and they should not be used beyond that period because they are rubber products. Both spare tires and those in use have a specific aging limit. Below is relevant information about tires: 1. Function: Tires are one of the most important components of a vehicle. Their main functions include: supporting the entire weight of the vehicle and bearing the load of the car; transmitting traction and braking torque to ensure adhesion between the wheels and the road; reducing and absorbing vibrations and impacts during driving to prevent severe vibrations and early damage to vehicle components; adapting to the high-speed performance of the vehicle and reducing noise during driving, ensuring safety, handling stability, comfort, and fuel economy. 2. Composition: Tires are usually composed of three parts: the outer tire, inner tube, and flap. Some tires do not require an inner tube, as they have an inner layer of rubber with excellent airtightness and require specialized rims. The structure of tires worldwide is evolving toward tubeless, radial construction, flat (with a low height-to-width ratio of the tire cross-section), and lightweight designs.
As a veteran who's worked in auto repair shops for twenty years, I've seen too many tragedies like this. New tires stored in warehouses for eight years may look shiny on the surface, but the rubber inside deteriorates badly and cracks immediately on the road. Last week, a customer insisted on using a nine-year-old spare tire, which blew out on the highway and nearly caused an accident. The sidewalls become covered with fine cracks, especially when exposed to sunlight, which accelerates degradation and drastically reduces grip. In rainy conditions, braking distance can double. Even if there's no visible wear, don't take the risk. I recommend checking the tire sidewalls and manufacturing date immediately, and ideally replacing them with new ones. Don't skimp on safety—it's priceless.
