Abstract:
A tire having an outer surface and plurality of circumferential and lateral grooves formed into the outer surface. The circumferential and lateral grooves extend to at least one groove depth to define a groove bottom surface. The circumferential and lateral grooves also define a plurality of tread blocks disposed around the circumference of the tire. The tire further includes at least one tie bar extending between at least two of the tread blocks and across at least one of the circumferential and lateral grooves. The tie bar is spaced from the groove bottom surface. In one aspect of the invention, the tire is manufactured in a mold and the tie bar is formed by a supplemental molding member that is removed from the molded tire after the main molding member has been removed from the tire.
