How often should car tires be rotated?

Tires, as the only component of a car that comes into contact with the ground, are extremely important for vehicle safety. Under normal usage conditions, there are two criteria for tire replacement: one is the duration of tire use, and the other is the mileage driven on the tires. Below is an introduction to these two scenarios: 1. Regarding the duration of tire use, the current lifespan of tires is approximately 3 to 5 years. Since tires are exposed to wind and sun for long periods, the rubber gradually ages and deteriorates under such conditions. Aged tires experience a significant decrease in strength, so if a tire reaches its lifespan, it must be replaced. 2. Regarding tire mileage, prolonged driving causes the tire surface to frequently slip and wear against the ground, gradually thinning the rubber thickness on the tire surface. This affects the tire's strength, making it more prone to blowouts or punctures. Therefore, tires have mileage limits; generally, tires need to be replaced after driving 50,000 to 80,000 kilometers.
I've been driving for over a decade and have gained considerable experience with tire replacement. The right time to change tires mainly depends on wear level and service life. Generally, you should have them inspected every 60,000 to 80,000 kilometers. If the tread wears down to reveal the wear indicator bars, immediate replacement is necessary. Additionally, rubber aging shouldn't be overlooked - tires typically harden and crack after about five years, significantly increasing blowout risks especially during summer heat or winter freeze. I make it a habit to check tread depth monthly using a coin; if the coin's head gets fully covered, it's replacement time. Avoiding sudden braking and maintaining proper tire pressure can extend lifespan, but safety always comes before cost savings. Regular wheel alignment also helps ensure even tire wear.
