When you take over new tires, do you observe the difference between their treads? Have you ever wondered what these patterns do to tires?
The history of the tire pattern is much younger than the tire itself. In fact, the first tire pattern appeared on the tire launched by Continental in 1904, which was also the world's first tire with a pattern. The appearance of the pattern is tantamount to a major change in the tire industry. As the pattern becomes more and more complex, what he has given to the tire is far more than a simple decorative effect. The secrets of how many tires are hidden in these criss-crossing grooves, today Tire Business brings you a good inventory.
Main and auxiliary grooves are matched with anti-skid water
First of all, even if you don’t know the knowledge of tire pattern, you can think of the function of grip through the grooves of the crisscross pattern, but the function of the pattern is far more than that. This is why pattern design is often the most complex and difficult step in tire development.
In fact, the cooperation between tire patterns is much more tacit than imagined. Among them, the longitudinal pattern is mainly responsible for drainage and heat dissipation because the direction of the groove is consistent with the circumferential direction of the tire, which is why the tire usually has 3-4 The wide longitudinal grooves facilitate the timely drainage of the tires. The closed or semi-closed transverse pattern of the tire is responsible for the grip performance of the tire. At the same time, by effectively matching the wide longitudinal pattern, the main drainage groove and auxiliary groove can be quickly drained and drained in heavy rain. Cut the water film to keep the tire as stable as the wet.
Shoulder blocks make driving more fun
In addition to good performance in wetlands, the driver's driving pleasure should also be considered at the beginning of the pattern design. Therefore, the design of the tread blocks is particularly important. Although the lateral grooves give the tire strong grip, if the shoulder pattern is not properly designed, it is easy to greatly reduce the grip performance and drainage performance of the tire when turning, especially when turning in rain. Few tire manufacturers will strengthen the tread block design of the shoulder, and some manufacturers will even design the tread block in the form of a pattern combination to improve the grip of the tire when cornering. Even in the rain, these shoulder blocks assist the main groove to help break the water film when the tire is cornering, thereby improving drainage performance on wet roads.
In the previous tire test, we found that the pattern of many tires has excellent braking and handling performance in the wet. It can be seen that the design of the pattern is very important for the performance of the tire and even the performance of the vehicle. effect.
The irregular arrangement of the pattern blocks is quieter
In addition, the pattern design also helps to reduce tire noise. Especially in the field of new energy vehicles, the design of patterns is very important for tire noise. At present, tire blocks with better mute performance on the market are usually irregularly ordered, because ordered blocks are usually accompanied by larger tire noise. Looking at the tires in your hand, you will also find that many of them are the variable-pitch design of the pattern blocks, which is a pattern design that reduces tire noise.
At the same time, tire manufacturers will also add closed grooves in the pattern to prevent tire noise from spreading in the air - directing the noise into the underbody to achieve a quiet effect.
These patterns are designed to be more fuel efficient
In addition, for many freight drivers, stone prevention, fuel saving, and wear resistance are also several necessary requirements. Therefore, many tire companies will adjust the pattern ratio when designing the tire pattern, trying to achieve the golden ratio to reduce the tire rolling resistance and realize the tire fuel saving. In addition, when designing truck tires, tire manufacturers will also adopt a zigzag pattern design to reduce the chance of stone trapping, reduce wear, and ensure a longer tire life cycle.
Asymmetrical patterns are king
It is almost certain that the more carefully designed the tire tread, the better its performance. After all, in addition to drainage efficiency and braking performance, the pattern is also related to the quietness and fuel economy of the tire, and even the full cycle life. This is why today's tire market can almost be regarded as a world of asymmetrical patterns, mainly because it can meet the different needs of drivers for tires, while ensuring the safe driving of tires in various road conditions, it can also play The advantages of tires in terms of handling, quietness, wear resistance and fuel economy.
Therefore, when we install tires on a daily basis, we must pay attention to the English prompts on the sidewall - inside is the inside, outside is the outside, and the tires are installed in the right direction to ensure performance.
