Tire tread comprising a plurality of rubber pads, each rubber pad being delimited by an incision of depth and of closed contour, this tread having: on a first portion, of a depth at most equal to 60% of the depth of the incision, blocking means designed to limit the movements of the lateral wall relative to the wall facing it, and on a second portion of the incision, of a depth at most equal to 60% of the depth of the incision and extending the first portion of depth, geometric shapes of second amplitude or that are rectilinear (that is to say of zero amplitude), the second amplitude being less than the first amplitude, and, the first portion of the incision delimiting a first portion of pad and the second portion of the incision delimiting a second portion of pad, the maximum sectional surface area of the second portion of the pad is greater than the maximum sectional surface area of the first portion of the said pad. |
