1.Supporting the weight and load of the car body: Supporting the weight of the car body, personnel, luggage, etc., mainly uses the air volume and pressure in the tires to support the weight and load of the car body, so it is very important to maintain a proper internal air pressure.
2.Transmission of driving force and braking force: In order to make the car move forward or stop, it is necessary to transmit the power of the engine and brakes to the road. This is mainly through the friction of the tire rubber. It is prone to idling and skidding, which is very dangerous.
3. Change and maintain the direction of the car: The car turns in the direction you want or keeps moving in a straight line under the control of the rider. This function is mainly performed through the friction and elasticity of the tire rubber and the firmness of the tire structure. Once the speed is over when turning If you quickly exceed the limit of the tire, you will not be able to go in the direction you want to turn, which is very dangerous, so please pay attention to the speed when riding.
4. Alleviate the impact from the road surface: This is the so-called "driving comfort" performance, which can alleviate the bumpy impact caused by the uneven road surface. This function is mainly through the air volume and pressure in the tire, the elasticity of the rubber, and the structure of the tire. Elastic, so the tire pressure is too high or too low will not work, please maintain the appropriate tire pressure.
