Adhesiveness between the tread member and a tire frame member is raised whilst reducing the volume of a tread member and decreasing rolling resistance. Air holes (18) are formed penetrating through to an opposite side from a ground contact face (12) at bottom portions (16A) of lateral main grooves (16) (grooves) of a tread member (10), such that air between the tread member (10) and a tire frame member (24) is expelled smoothly into the lateral main grooves (16) (grooves) through the air holes (18) when adhering the tread member (10) to the tire frame member (24). This is particularly effective when a gauge (G) at the bottom portions (16A) of the lateral main grooves (16) (grooves) is made thin in order to reduce the volume of the tread member (10).
