Hyundai Motor and Kia have unveiled a snow chain-integrated tire to increase safety on slippery winter roads.

Snow chain-integrated tire technology uses shape memory alloy modules that are located inside the wheel and tire, Hyundai said.

When the driver presses a button, the modules protrude to act as a "snow chain."

During normal driving, the shape memory alloy located inside the wheel is compressed into the shape of the letter "L" and does not contact the road's surface. When the driver activates the function, the shape memory alloy reverts to its original profile and the material forms a "J" shape, pushing the module out of the tire to make contact with the surface.

It improves grip, stability and safety on snow roads and also reduces the inconvenience of installing snow chains every time in snowy conditions.

“This technology reflects our commitment to turning advanced technologies into real-world solutions that benefit customers,” said Park Joon-mo, head of the advanced chassis development team at Hyundai Motor. “We will continue to develop technologies that enhance the safety and convenience of our vehicles and bring value to our customers.”

Hyundai and Kia applied for patents for the technology in Korea and the United States. Mass production will be discussed later.
