Provided is a pneumatic tyre tread capable of mitigating air column resonance and maintaining drainage performance while ensuring that the flexible fences are abraded to a similar extent to the tread portion. A pneumatic tyre tread 1 of the present invention is formed from a rubber composition, and has a tread portion 2 in which a primary groove 3 is formed and multiple flexible fences 4 formed in the primary groove; the flexible fences are formed from at least a rubber composition for fences that is different from the rubber composition for the tread portion; the rubber composition for fences of the flexible fences has an abrasion index that is more than or equal to twice the abrasion index of the rubber composition of the tread portion; and the rubber composition for fences comprises a filler composition that is based on (a) a diene elastomer, (b) a reinforcing filler selected from the group consisting of carbon black, inorganic fillers, organic fillers, and mixtures of said fillers, which has a BET specific surface area of less than 100 m 2 /g and is in an amount of between 20 phr and 120 phr, preferably between 30 phr and 100 phr; (c) a plasticizing system selected from the group consisting of liquid plasticizer, hydrocarbon resins and mixtures thereof; and (d) a vulcanizing agent.
