The first tires were made of wood, which can be seen from ancient Chinese chariots and foreign gentlemen's carts. Later, when explorer Columbus explored the new world in 1493-1496 for the second voyage to the island of haitians in the west Indies, he was taken aback by the fact that the local kid was playing with a hard piece of rubber. Later, he brought this wonderful thing back to his homeland. After several years, rubber was widely used, and the wheels were gradually made from wood to hard rubber. But the rubber tires were solid, and they were uncomfortable and noisy. It was not until 1845 that the Scottish civil engineer, r.w.
