How old can the tires be when picking up a new car?

The production date of the tires on a new car should preferably not exceed six months. The shelf life of car tires is generally 3-5 years, as the main material of car tires is rubber, which naturally ages over time, leading to a decline in tire performance. In practice, the service life of car tires depends on specific usage conditions. To extend tire lifespan, proper tire maintenance during daily driving is essential: 1. Maintain distance: Keep a safe distance when driving at high speeds to avoid unnecessary or frequent braking, which can damage tires. Also, for safety reasons, pay attention to the tread depth. Worn-out tires with reduced friction against the road surface have longer braking distances and should not be used for high-speed driving. 2. Correct loading: There is a direct relationship between tire load and pressure. Overloading is similar to underinflation and can cause tire damage. Frequent overloading can reduce tire lifespan by 20%-50%. Incorrect loading methods can also lead to uneven tire wear, causing excessive load on individual tires and shortening their lifespan. 3. Maintain proper pressure: Tire pressure is crucial for tire health. The inflation pressure must comply with national standards for different types and specifications of tires. Regularly check tire pressure, as both overinflation and underinflation can cause irregular wear, tread groove cracking, cord breakage, ply separation, and tire blowouts. For sustained high-speed driving, the pressure should be increased by 5%-10% above the standard pressure. Additionally, tire pressure rises due to temperature increases during driving, and air should not be released at this time. 4. Tire rotation: Rotate tires appropriately and timely (check during vehicle primary and secondary maintenance) to ensure even wear and extend lifespan. Tires with slightly larger outer diameters should be installed on the outer wheels. 5. Tire selection: Do not use retreaded tires on the front wheels. Front wheels should preferably use tires with vertical tread patterns, while rear wheels should use tires with horizontal tread patterns.
