Finnish company develops convertible tire cleats for snow ejection

According to foreign media reports, a Finnish company has announced its first " convertible" tire that can be converted into a snow version at the push of a button. At this point, the cleat will be ejected from the tire so that it will produce a better grip in an ice-snow environment.

Finland’s Nokia, which acquired the invention, said that the unique cleat technology will allow the cleat to stick out of the tire if necessary. Maddie Murray, tire technology customer service manager at the tire company, said: "As a pioneer in the winter tyre industry, we have confirmed that the combination of cleats and cleat-free winter tyres can be combined perfectly. Drivers only need to press the button. The cleats will pop up to increase the grip on the tires, and when they are not needed, they can be retracted into the tires. The idea of ​​combining a non-soled tire with a cleat has the idea that drivers can Change this when the environment changes significantly."

On dry roads and stable winter conditions, cleats are not used, but they are activated for safety in snow and ice. The concept tire of the world's top winter tire specialist uses the same tread pattern as the recently introduced Nokian Hakkapeliitta 8SUV stud winter tire. The cleats on the four tires can be ejected or retracted at the same time. The main part of the cleat remains in place, and its active part is a hard metal pin in the middle of the cleat. Murray said: "This new concept tire is an amazing scientific and technological feat. Its unique cleat concept may one day become a reality."

Air Cannon, also known as air to flow, broken GongQi, air, are suddenly out of the compressed gas turbulence, the speed of more than a Mach (sound) directly into the storage medium material block fault zone, the sudden release of the expansion of the shock wave, overcome the static friction materials, and make the container of the material flow back again.
