The technology utilizes shape memory alloy modules embedded inside the wheel and tire. These modules, upon receiving an electrical signal, protrude to function as an improvised snow chain. This feature offers a stark contrast to conventional snow chains, which often require manual installation and removal.

The snow chain-integrated tire technology is comprised of a wheel and tire assembly that includes radial grooves at regular intervals. Shape memory alloy modules are inserted into these grooves. In normal driving conditions, the alloy inside the wheel is compressed into an ‘L’ shape, remaining unobtrusive and not in contact with the road surface. When activated, an electric current causes the shape memory alloy to return to its original shape, extending out of the tire to interact with the road, thereby improving traction in snowy conditions.

A unique aspect of this technology is its ability to self-indicate wear. When the tire surface wears down to the height of the module in its inactive state, it signals the need for tire replacement, ensuring consistent safety.

This technology is currently in the patent-pending phase in both South Korea and the United States. Both automakers are considering the mass production of this system following further technological refinement, as well as comprehensive durability and performance tests.

This innovative solution was revealed on the Hyundai Motor Group’s YouTube channel, highlighting a significant advancement in automotive technology, and it can be seen here.
