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 filler A, which is more than 50 phr of filler A in which the filler particles are nanoparticles having an average grain size (by weight average) smaller than 500 nm; and (c) a filler B, which is more than 50 phr of filler B in which the filler particles are microparticles having a median grain size (by weight average) larger than 1 µm.
