At that time, he was actually just a surgeon because he loved his son very much. At that time, his son's bicycle still used solid rubber wheels, which was very bumpy to use. In order to alleviate this situation, he used a tube inflated through a valve and protected it with rubber to make a 1 device, which can be wound on the wheel. In fact, the new tire he just started making was laughed at by everyone.
Later, his son took part in the competition with this car and won 1. It is because of this time that his invention really attracted everyone's attention. At the same time, he applied for a patent for his invention and built a tire factory.
In fact, it was because he gave up his career as a veterinarian at first, and then built this tire factory, which promoted the development of bicycles and cars. The earliest tires were actually white because they were made of natural rubber.
But at first, this kind of natural rubber was not ideal in all aspects, for example, its tear resistance was not strong, and it was very easy to age. It was not until later that some companies added carbon black in their manufacturing, so they turned the tires black. When carbon black is combined with this rubber, the rubber will become stronger. After a slow evolution, everyone accepted black tires, just like the current tire industry, black is definitely dominant.
So the earliest tire in the world actually evolved because of a father's love for his son. Later, more companies and manufacturers developed tires, and then there were more bicycle tires, motorcycle tires, tricycle tires and automobile tires.
