What is the reason for the high tire pressure in new cars when they leave the factory?

[StHailey]

The reason for the high tire pressure in new cars when they leave the factory is to facilitate transportation and storage. The method to check the tire date on a new car is by looking at the production batch number on the outer edge of the tire. The production batch number is a set of numbers and letters that indicate the manufacturing year, month, and quantity of the tire. The functions of tires are: 1. To support the entire weight of the vehicle, bear the load of the car, and transmit forces and moments in other directions; 2. To work together with the car suspension to mitigate the shocks encountered during driving. Precautions for using a new car include: 1. Before starting a new car, it is necessary to warm it up first to give the engine a lubrication period, which is beneficial for both the car's motor and engine; 2. There are speed requirements for new cars during the break-in period, with domestic cars at 40 to 70 kilometers per hour and imported cars at 100 kilometers per hour.
