<p>A tire (100) having an asymmetrical tread pattern (103) having lateral ribs (109, 111) having substantially equal circumferential surface contact areas and substantially unique contact surface ratios, and at least one rib pair (114) formed by a medial rib (113; 115) on the inner (105) and the outer side (107) of the tire, the medial ribs (113, 115) having substantially equal circumferential surface contact areas and substantially unique contact surface ratios; and a longitudinal groove (127, 129, 131, 133) located between adjacent ribs. The tire (100) is manufactured by the method steps of: removing one half of a clamshell mold from a first symmetric tire mold assembly; removing one half of a clamshell mold from a second symmetric tire mold assembly; combining the clamshell mold halves to form an asymmetric tire tread mold assembly; providing a green tire to the asymmetric tire tread mold assembly; treating the green tire; and removing the tire from the asymmetric tire tread mold assembly.</p> |
