Tyre with projection diversion device

The present invention is a tire (1) which has the tread (2) provided with the flange (3), A flange is prolonged in the direction of an axis, and a radial direction toward the inner side of a tread, and a tread is rolling, It has the side prolonged in the direction of an axis in the each side of the rolling contact surface (21) and tread in contact with a road surface, It is related with the tire which further has the direction rib of the circumference (4) into which the tire is provided in the one flange near the tread, water splashes off in a transverse direction (directions congruous in the direction parallel to the axis-of-rotation line of a tire) when running the wet road surface top, and height is changed. The direction rib of the circumference (4) has a device (5) from which the flow of water splashes 飛ばし is diverted during rolling on the road surface covered with water, and this device (5) has projected on the direction rib of the circumference (4), and is formed by a plurality of projections (51) arranged in the direction of slanting to a transverse direction. The direction rib of the circumference (4) further has a plurality of studs (6) which decrease the power of a flow during rolling on the road surface covered with water, and these studs (6) divert and are provided between the projections of a device (5).
