How much difference between tire date and car date is unacceptable?

[NoahFitz]

Tires with a date difference of more than 1 year from the car's date are unacceptable. Tires have a shelf life, generally not exceeding 3 years from the production date. Therefore, when purchasing tires, choose those produced within the last 3 years, and avoid tires with a production date older than 5 years. Below are the functions of car tires: Supporting the vehicle's total weight: Car tires support the entire weight of the vehicle, bear the load of the car, and transmit forces and moments in other directions. Enhancing vehicle performance: Car tires transmit traction and braking torque to ensure good adhesion between the wheels and the road surface, improving the car's power, braking, and passability; they work with the car's suspension to mitigate impacts during driving and dampen resulting vibrations. Preventing early damage to car components: Car tires protect vehicle components from severe vibrations and early damage, adapt to the vehicle's high-speed performance, reduce driving noise, and ensure safety, handling stability, comfort, and energy efficiency.
