Quiet cotton tires are definitely not IQ tax
As people's requirements for car comfort are getting higher and higher, today's car owners are becoming more and more picky about the quiet performance of tires when purchasing tires. Especially in recent years, the popularity of new energy vehicles has made car owners have higher requirements for tire quietness.
What is a quiet cotton tire
Quiet cotton tires are not new in the market. After technical research and development, tire companies stick a layer of quiet cotton inside the tire to effectively reduce tire noise. This seems to be a simple layer of sponge, but it is the crystallization of the wisdom of tire companies. Small workshops can also directly install quiet cotton on ordinary tires, but the quiet effect is not so obvious. In addition, ordinary quiet cotton is not heat-resistant. High temperature will be generated inside the tire during rolling, but quiet cotton tires specially treated by tire manufacturers do not have this phenomenon.
The essence of tire noise
The main source of tire noise comes from the noise of the tread blocks hitting the ground during driving. Car owners who have used high-performance street tires have a deep understanding that the larger the tread blocks, the greater the rolling noise. This is actually the "pumping noise" when the tire rolls. When the tire pattern rolls on the road, the rubber block of the tread pattern will deform, causing the air between the tire pattern and the road to be continuously "compressed" and "released", and the air will burst out with noise.
How do traditional tires control noise?
So how do traditional tires control noise? The technical approaches used by traditional tires to control noise mainly include softening the tread rubber (rubber material formula) and optimizing the tread pattern design. By using a softer rubber material, the bouncing impact of the tire is reduced; by optimizing the pattern reasonably, the "gear effect" of the tire rolling is reduced.
How silent cotton tires deal with noise
But silent cotton tires have another "killer": using specially optimized special polyurethane silent cotton to actively absorb the rolling noise of the tire. If the silent method of traditional tires is "try to avoid noise generation", then the silent method of silent cotton tires is "active sound absorption". Of course, the real silent cotton tire method to deal with noise is "multi-pronged approach".
And the special silent cotton in the tire body can be specially optimized according to the noise frequency generated when the tire actually rolls. The sound absorption efficiency is strong, especially the impact noise of tire bouncing has a very efficient absorption capacity. Therefore, the silent cotton tire can remain quiet and comfortable when driving on various roads with different roughness.
People have never stopped pursuing the quietness of tires. In the past, due to the loud engine noise, the noise of tires was difficult to detect. But now with the increasing quietness of vehicles and the emergence of electric vehicles, the noise of the vehicle itself has been greatly reduced. At this time, the problem of tire noise is highlighted. This is especially true for some electric vehicles without engines. This forces tire companies to develop quieter tires.
The silent cotton tires developed by major tire companies with huge financial and material resources are not useless IQ taxes.
