Why do cars now have four wheels instead of three? I believe there are many people. Are thinking about this problem. How to answer this question? In fact, after the steam revolution, the first car had three wheels. This car was invented by karl friedrich Benz, a German, and the brand Mercedes-Benz was born. This is the problem. The first car in the world had three wheels. Why do they all have four wheels now? In my opinion, there are only the following reasons.

The first is based on the aesthetics of modern people. A four-wheeled car will look more decent, generous and beautiful in appearance, so most brands that produce cars now choose four-wheeled instead of three-wheeled, followed by safety issues. Although the three-wheeled vehicle is the most stable in mathematics, it is easy to overturn when turning or going uphill, and the probability of this happening in the four-wheeled vehicle will be greatly reduced, and the four-wheeled vehicle will also give people a very comfortable driving feeling.

What I want to talk about now is the problem in driving. The center of gravity of tricycle deviates from the sideline more than that of four-wheeled vehicle. Therefore, during driving, the tricycle always has one wheel, which bears more weight than the other two wheels. Because of this, the tricycle is very easy to overturn when turning, and the four-person body can avoid this very well. The reason is that after the car becomes a car, its center of gravity will cross the middle of the area at that time, so that it can be more stable when driving.

Finally, the cost. The reason why a car has four wheels instead of three wheels is because of the cost. Four wheels can not only maintain stability and flexibility, but also save more costs. If a car is equipped with seven or eight tires, it will reduce flexibility and increase costs. Large trucks and even larger cars will use more than four tires.

In a word, most modern cars have four tires instead of three.
