Tires have evolved from solid without a pattern to radial with a pattern, from being able to roll to various performances today, and the performance of tires has also developed from the initial single, incompatible situation, to the current comprehensive development. The development speed of tires is far beyond our imagination. I believe everyone must have heard such a sentence before, "The better the handling performance of the tire, the worse its quietness", but this is already a thing of the past.
If you want to understand why there was such a view before, you have to start with the handling and quietness.
When it comes to handling, it means vehicle handling. There are certain differences in the cognition of vehicle handling in China and Europe and the United States. Common car owners in my country believe that handling includes vehicle power acceleration performance, drivability, steering, extreme handling, comfort, and braking performance, while in Europe and the United States, handling is considered to include steering and extreme handling.
The so-called steering refers to the reaction of the vehicle after the driver turns the steering wheel during daily driving. This response includes changes in the pointing of the front of the vehicle, changes in the vehicle's lateral movement, etc. In layman's terms, vehicle steering sensitivity refers to where to hit.
The limit control refers to the reaction of the vehicle and the feedback to the driver when the vehicle reaches the limit area, such as tail flick, drift, sideslip and so on caused by understeer and oversteer.
Steering and tires are closely related in daily driving without considering extreme handling. The tires provide the vehicle with great grip. If the tires slip during the steering process, it is likely that the tires have insufficient adhesion. Of course, the road is wet or the speed is too fast when cornering. Low adhesion is still the most influential reason.
It is easy to understand the quietness, which is aimed at the treatment of tire noise to achieve the purpose of reducing tire noise. Generally speaking, the tire material with good quietness is soft, and the pattern is asymmetrical. For example, the German Continental TCGOLD adopts a frequency conversion noise reducer and a closed shoulder design, which greatly reduces tire noise and improves driving comfort.
Can't have both?
What the handling requires is the strong grip of the tires and high adhesion to the ground, which can firmly stick the vehicle to the road. Harder tread material and deeper grooves will increase tire noise to a certain extent. The quietness requires shallower grooves and softer tire treads to achieve the purpose of reducing tire noise.
So it seems that there is a contradiction between the two. It seems that the stronger the handling, the louder the tire noise and the worse the quietness. But the way to deal with tire noise is not only from the material and groove depth. Like the German Continental TCGOLD, it adopts asymmetrical patterns, variable pitch, and some black technologies to reduce tire noise. In this way, it does not change the grip of the tire, Under the premise of improving adhesion, it can also reduce tire noise.
In the past, handling and quietness were indeed incompatible, but now a balance has been achieved, with both handling and quietness.
With the continuous development of the tire industry, there is much benign competition among different brands, and black technologies are increasing. What we thought was impossible in the past is gradually becoming a reality.
