Abstract
A tire chain cross member assembly comprises a flexible cable on which is tightly wrapped a helical wire sheath. The sheath is surrounded by a first layer of helical wire sleeves that are free to move axially and circumferentially on the sheath. Sleeves of the first layer are surrounded by a second layer of helical wire sleeves that are free to move axially and circumferentially and that form traction elements. A tire chain comprises a pair of elongated side members and a plurality of the cross member assemblies.
