Bearing Car Weight
Tires cushion lowers the impact from the road by bearing the car weight, while also transfers the engine power, braking power and change of direction to the road to maintain the movement of the car. Tires require air injection by adopting the structure and compound to bear the great load of cars. Sometimes, the tube inside the tire is used, but in the tubeless type in which the rubber that serves as the tube is attached on the inside of the tire, the air is injected after the tire is assembled with the wheel, and thus requires a firm connection. Moreover, car load and running stability can only be guaranteed by maintaining optimal air pressure. Tires are developed in various and complicated forms by applying performance and wheels due to the recent trend of high quality and high performance in vehicles.
