Can Stock Tires Be Used?
2 Answers
Generally, stock tires cannot be used after 3 years. Newly produced tires need to be stored for 8 to 12 months before entering a stable period, and stock tires cannot be used after 3 years. This period is calculated from the production date, not the purchase date. Typically, the sidewall of a tire indicates the production date with a four-digit code, such as 0717, which means the tire was produced in the seventh week of 2017. Below is relevant information about tires: Tire lifespan: The wear lifespan of a tire is 30,000 to 50,000 kilometers. If the tire has not reached the wear limit or mileage but has been in use for 5 years or has developed significant cracks on the sidewalls, it should be replaced. Tire material: The main component of a tire is rubber. The maximum storage and anti-aging period for rubber, from natural latex to EPDM and nitrile, does not exceed 10 years, with an average service life of 3 to 5 years for various rubber products in use.
As someone who has been working with cars for years, I've seen plenty of issues with stock tires. They might seem usable, but caution is needed. Tires age even when not installed – rubber deteriorates over time, especially if stored for long periods, leading to cracks or hardening. The production date is crucial; look for the four-digit code on the tire sidewall (first two digits = year, last two = week). Avoid using tires older than 5-6 years. Storage conditions matter too – cold or dry environments may preserve them, but heat and humidity accelerate deterioration. Safety is non-negotiable; a blowout at highway speeds could have serious consequences. My advice: inspect carefully before use – check for visible aging signs and consult someone knowledgeable. Don't risk major problems to save small money. Safety first – new tires are the wisest choice.
