The earliest tires were made of wood, as can be seen from the ancient Chinese chariots and foreign gentlemen's carriages. Later, when the explorer Columbus, who explored the New World for the second time in 1493-1496 to reach the island of Haiti in the West Indies, he was surprised to find a piece of rubber that was played by local children. Later, he brought this wonderful thing back to the motherland. After several years, rubber has been widely used and the wheels have gradually changed from wood to hard rubber. At this time, the rubber tire was still solid, and it was still uncomfortable to walk on and it was very noisy. The first person to buy a pneumatic tire was named Rowe, an aristocrat. The total price of the four tires was 42 lbs. two shillings. In 1847, "Science USA" magazine introduced Thomson's pneumatic tires, calling it an epoch-making improvement. However, at that time, the United Kingdom paid too much attention to traditional gentrification. In order to protect carriages and limit the development of steam cars, the speed of automobiles was limited to 2 mph (about 3.2 km) in the urban areas and 4 mile (about 6.4 km) in the suburbs. In this way, Thomson's invention had no market, so it was slowly forgotten. In other words, Thomson's first tire revolution did not bring the same light to the human eye, because the darkness that mankind should endure seems to have not yet reached the end. But the sun always comes out, because humans and everything needs it. In 1888, more than 40 years later, in England, the veterinarian's Englishman, J.B. Dunlop, patented pneumatic tires. At the time, J.B. Dunlop’s 10-year-old son, Johnny, bought a three-wheeled bicycle, but because the tires were all solid tires made of hard rubber, they didn’t walk on a rocky road. Comfortable, his son's complaint inspired Mr. Dunlop's inspiration, so the pneumatic tire that had been forgotten for more than 40 years was once again available. With the progress of the times, the pneumatic tires invented by Mr. Dunlop soon got its application on bicycles and quickly moved into the automobile field, which made a great contribution to the development of the world automobile industry.
