What Are the Criteria for Replacing Car Tires?

[JoshuaMarie]

Replacement criteria for car tires include the tire's usage duration, mileage, and the presence of wear conditions. It is important to observe and replace them in a timely manner. Below are the detailed explanations: Tire Usage Duration: The primary material of tires is rubber, which has a limited lifespan. Generally, the service life of a tire is about 3 to 5 years. Since tires are exposed to wind and sunlight for extended periods, the rubber gradually deteriorates and ages under such conditions. Aged tires experience a significant decrease in strength, so if a tire reaches its lifespan, it must be replaced. Tire Mileage: With prolonged driving, the tire surface frequently slips and wears against the ground. During this wear process, the thickness of the rubber on the tire surface diminishes, affecting the tire's strength. Over time, this can lead to tire blowouts or punctures. Therefore, tires have mileage limits, and generally, they need to be replaced after traveling 50,000 to 80,000 kilometers. Tire Damage: Scrapes on the sidewalls of vehicle tires can cause damage. The sidewalls of tires are very weak in strength, and any damage can easily lead to tire blowouts or bulges. Such tires can only be replaced.
