Embodiments of the disclosure include a tire tread having tread blocks (24) each defined by a pair of lateral grooves (20) each being asymmetric whereby a first portion (26) of a trailing side (TS24) the tread block is inclined and extends to a peak (28), and whereby a recess (38) projects into tread block below the first portion. Each tread block also includes a sipe (22) extending into the tread thickness from the outer, ground-engaging side of the tread, where the sipe is generally inclined relative to the direction of the tread thickness, such that as the sipe extends into the tread thickness from the outer, ground-engaging side, the sipe extends towards the trailing side (TS24) of the corresponding tread block, the sipe including a groove (40) arranged along the sipe within the tread thickness and spaced below the outer, ground-engaging side of the tread. The groove being asymmetric relative to a centerline (CL22) of the sipe.
