To provide a tread for a pneumatic tyre in which air column resonance sound is reduced and wear of the groove fences and wear of the tread portion are caused to be approximately the same, while drainage performance is maintained. In the tread for a pneumatic tyre according to the present invention, a plurality of groove fences 4 are formed and are installed within at least one circumferential groove 2, extending from the bottom 21 of the circumferential groove 2, and block at least 70% of the cross-sectional area of the circumferential groove 2, and the bending parameter of the groove fences 4, defined as E·I/(h 3 l) (where E is the modulus at 10% elongation of the material used for the groove fences, I is the second moment of area of the groove fence, h is the height of the groove fence, and l is the width of the groove fence) is at least equal to 250Pa and at most equal to 350Pa.
