<p>A cable type tire chain (10) has traction sleeves (16) on the cross members (14) located only adjacent to the shoulders (40) of the tire (20). The center portion (42) of the cross members adjacent to the middle of the tire tread is free of traction sleeves. The traction sleeves are spaced away from the middle of the tire tread by either a coil spring (46) through which the cross member cable (28) extends or by beads (52) attached to the cable. The cross members are attached directly to the side members (12) of the tire chain by flat profile hooks (26) formed from rectangular strips of metal, so that the cross members lie close to the sidewalls (50) of the tire. The invention provides improved traction and reduced wear of both the tire and the tire chain. </p> |
