ABSTRACT:
A medium truck tire (10) and more specifically a super single truck tire (10) includes belt plies (22, 23, 25) reinforced with steel cords which make an angle comprised between 0° and 5° with respect to the equatorial plane. Disposed between in embedded fashion between two of the belt plies (23, 25) is a pair of substantially full spiral helically wound overlays (24). The steel of the reinforcing cords comprises high elongation steel. The spliced belt plies (22, 23, 25) are in a RLL configuration making angles comprised between 45° and 75° with respect to the equatorial plane angular direction of the inwardmost ply (25) oppositely disposed relative to the outer plies (22, 23). The helically would layers (24) are disposed between the inwardmost R ply (25) and a radially outward L ply (23).
