OVATION is a Delta brand tire. Tire is a circular elastic rubber product which is assembled on various vehicles or machinery and rolled on the ground. Usually installed on the metal rim, it can support the car body, buffer the external impact, achieve contact with the road surface and ensure the driving performance of the vehicle.
tires are often used in complex and harsh conditions, and are subjected to various deformations, loads, forces and high and low temperatures during driving, so they must have high bearing performance, traction performance and cushioning performance. It also requires high wear resistance and bending resistance, as well as low rolling resistance and heat generation. Half of the rubber consumption in the world is used in the production of tires, which shows the ability of tires to use rubber.
Extended information:
1. The earliest tires were made of wood, which can be seen from China's ancient chariots and foreign gentlemen's carriages. Later, when the explorer Christopher Columbus sailed to Haiti in the West Indies for the second time in 1493-1496, he was surprised to find the rubber blocks played by local children. Later, he brought this wonderful thing back to the motherland. A few years later, rubber was widely used, and the wheels gradually changed from wood to hard rubber.
2. But at this time, the rubber of the tire is still very strong, and it is uncomfortable to walk and noisy. It was not until 1845 that R．W． Thomson, a Scottish-born civil engineer, invented pneumatic tires, and the British government applied for a patent in the name of "improvement of the wheels of carriages and other vehicles". On December 1th of the same year, the first pneumatic tire was born. The first person who bought pneumatic tires was Lei, a nobleman. The price of four tires was forty-four pounds and two shillings.
