The bead reinforcing plies have cords (21) therein that are substantially parallel to each other and are arranged so that the cords (21) in one reinforcing ply (15) are substantially parallel to the cords (21) in the other ply (16). A direction mark (23) is located on an external surface of the tire to show the direction of the reinforcing cords (21) in relation to the rotational direction of the tire.</p><p>When such tires are mounted on the axle unit they may be arranged so that the direction marks are pointed all in the same rotational direction.</p> |
