ABSTRACT:
A tire molding method as disclosed wherein a segmented mold (2) has lugs (40) in the shoulder regions of the segments (4) with complimentary lug extensions (30) in the sidewall forming annular rings (6,8). The lug extensions (30) align with and form the appearance of a lug (40) that extends radially inward well into the sidewall of the tire (20). the resultant tire (20) and the mold (2) for making the tire (20) are less costly to fabricate than prior art segmented molds.
