Do I need to read an almanac to change a tire?

No need. Tire is one of the most important parts in a car. Its main functions are: supporting the overall weight of the car, bearing the load of the car, transmitting the traction and braking torque, ensuring the adhesion between the wheels and the road surface, reducing and absorbing the vibration impact when the car is driving, improving the speed, ensuring the safety performance, maneuverability and comfort, preventing the early violent vibration and damage of the car parts, adapting to the high-speed performance of the car, reducing the noise when driving, etc. There is no need to look at the Gregorian calendar when changing tires.
