Hyundai and Kia's new integrated snow chain tires.

Hyundai Motor and Kia unveiled a new chain-integrated tire technology, using shape memory alloy modules located inside the tire and wheel. When an electrical signal is pushed through these modules, they protrude from the tires to provide additional traction in snowy terrain.

This innovation, which will hopefully be introduced on Hyundai and Kia vehicles someday, reflects our commitment to turning advanced technologies into real-world solutions that benefit customers. We will continue to develop technologies that enhance safety and convenience of our vehicles and bring value to our customers.” – Head of Advanced Chassis Development Team, Joon Mo Park

These memory alloys are put into radial grooves along the tire and wheel, compressed and out of the way in a ‘L’ shape when not in use. With the simple push of a button, an electric current forms the allows into a ‘J’ shape, pushing the ‘chains’ beyond the tire and improving grip.

Additionally, because of the module’s location, it can act as a warning for when tires need to be replaced due to wear. The product is currently patent pending in South Korea and the United States.

Hyundai Motor and Kia plan to consider mass production of the tires after further technological development, durability and performance tests and regulation reviews.
