Provided is a pneumatic tyre tread that can maintain a good level of water drainage performance up to the final stage of wear of a tread part. The pneumatic tyre tread according to the present invention is formed with a plurality of flexible fences 4 which are disposed inside at least one main groove 3 extending from the bottom surface 33 of the main groove 3 and obstructing at least 70% of the cross-sectional area of the main groove 3, the flexible fences 4 comprising an inside portion having a connecting part 411 which is connected to the main groove 3, and an outside portion which is radially outside a predetermined height D1 from the bottom surface 33 of the main groove 3, and the average angle of inclination of the inside portion with respect to a line perpendicular to the surface of the tread part in contact with the road surface is greater than the average angle of inclination of the outside portion. |
