Abstract
A system of manufacturing a high-lug tire, wherein a portion of the tread of an unvulcanized tire is cut off to form quasi pattern grooves in substantially complementary relation to the shaping surface of a vulcanizing mold. Thereafter the unvulcanized tire is vulcanized in vulcanizing mold with the quasi pattern grooves matching the shaping surface of the vulcanizing mold. This reduces any flow of rubber during vulcanization of the tire.
