How old is acceptable for newly purchased tires?

[SaraMarie]

Newly purchased tires are considered acceptable if they are no more than three years old, and the closer the production date, the better. Tires are rubber products, and rubber products will age even if left unused for extended periods. Generally, the shelf life of unused tires is three years, so avoid purchasing tires that have been in storage for over three years. Once installed on a vehicle, tires can be used for four years, and should be replaced every four years. When buying tires, pay attention to: 1. Choose reputable tire brands; 2. Purchase from authorized dealers or stores with good reputations; 3. Verify the correct tire size for your vehicle; 4. Check the tread depth and pattern; 5. Pay attention to the tire's production date; 6. Avoid retreaded tires.
