Now look down at your soles and see if there are many patterns. The reason is the same.

Of course, so is this model. Tire is the only thing that touches the ground, which has a great influence on the adhesion of the car on the ground, and the adhesion affects the driving performance of the car.

Where there is water on the ground in rainy days, cars will splash when they pass by, which is the drainage ability of tire patterns. When a car with a speed of 60km/h passes through the water, it may be driving on the water, not on the ground. This is also the main reason why traffic accidents are prone to occur in rainy days.

Most vehicles use rubber tires, which have many uneven patterns. Different vehicles have different tires, and the patterns have different shapes and widths. Do you know why?

The original pattern on the vehicle tire is to increase the friction between the wheel and the ground and prevent the wheel from slipping on the road. Setting patterns on tires is constantly changing in practice, and only now is it more perfect and scientific. At present, people are used to dividing wheel patterns into three categories: general, high field and combined patterns, and their geometric shapes are generally vertical straight lines, horizontal straight lines, diagonal lines, blocks and mixed patterns.

General patterns, also known as road patterns, are the earliest and most common patterns, such as vertical straight patterns and sawtooth patterns common on bus tires, which can eliminate noise, so they are also called silent patterns; The high moon field pattern is specially designed for vehicles driving in wilderness and soft soil, and most of them have wide and deep grooves, which are not easy to catch stones, hide soil and slip when driving; Combined tread tires can be used not only on hard roads and gravel roads, but also on soft, muddy or snow.
