摘要： A radial tire for heavy duty vehicles has a tread surface provided with at least a main groove (4) extending in the tire circumferential direction, a slot (9) with a slot width (HS) of 3 to 6 mm, and siping (11). A groove bottom (3) of the main groove (4) is in a zigzag form, and a groove upper edge line (8) of the main groove (4) on the tread surface has outer and inner groove upper edge line (M1, V1) repeated alternately and each extending in the tire circumferential direction. The distance (hu) in the tire axial direction between the outer and inner groove upper edge lines (M1, V1) is smaller than the deflection width (hl) of the zigzag groove bottom. The groove wall of the main groove (4) has hill protrusions (6) each having an inclined groove wall part (5) extending from the external angle portion (M) of the zigzag groove bottom to the outer groove upper edge line (M1). The slot (9) is formed in the inclined groove wall part (5) with the depth (DS) in the tire axial direction from the inclined groove wall part (5) increasing gradually inward in the tire radial direction. The siping (11) is formed in the inside wall (10) of the slot (9) with the depth (DC) in the tire axial direction from the inside wall (10) being constant or increasing gradually inward in the tire radial direction.
