TIRE PRODUCTION METHOD, TREAD MEMBER, AND TIRE

摘要

By reducing the volume of a tread member and decreasing the rolling resistance, adhesiveness between the tread member and a tire skeletal member is increased. A tread member (10) is provided with a vent (18) positioned at the bottom portion (16A) of a lateral main groove (16) (groove),and which penetrates to the side opposite to a grounding surface (12), so that when the tread member (10) and the tire skeletal member (24) are adhered, the air between the tread member (10) and the tire skeletal member (24) can be smoothly discharged through the vent (18) to the inside of the lateral main groove (16) (groove). This is particularly effective when a gauge (G) of the bottom portion (16A) of the lateral main groove (16) (groove) is thin in order to reduce the volume of the tread member (10).
