In the case of twin tyres, blocks D' connected by chains C are arranged in the groove between the tyres B, so that each block has rolling contact with the road surface, and can also rock in a direction transverse to the plane of the wheel. In the case of single tyres, a ring of blocks may be arranged at either side, a flange &c. being provided on the rim for retaining the ring.
