1 What is quiet cotton tire

Quiet cotton tires are not new in the market. They are tire companies that have applied a layer of quiet cotton inside the tire after technical research and development to effectively reduce the noise of the tire. This seemingly simple layer of sponge is the crystallization of the wisdom of tire companies, and small workshops can also directly install quiet cotton on ordinary tires, but the quiet effect is not so obvious, and ordinary quiet cotton is not heat-resistant. High temperature will be generated inside the tire during rolling, but quiet cotton tires that have been specially treated by tire manufacturers do not have this phenomenon.
