Tyre tread (1) comprising a plurality of rubber blocks (3), each rubber block (3) being delimited by an incision (2) of depth (H) and closed contour, this tread being such that: over a first part of depth (P1) at most equal to 60% of the depth (H) of the incision (2), immobilizing means intended to limit the movements of the side wall (31) in relation to the wall (31') opposite, and over a second part of the incision, of depth (P2) at most equal to the 60% of the depth (H) of the incision and extending the first part of depth (P1), geometric shapes of a second amplitude or which are rectilinear (that is to say of zero amplitude), the second amplitude being less than the first amplitude, and such that the first part of the incision delimiting a first bit of block and the second part of the incision delimiting a second bit of block, the maximum cross-sectional area of the second bit of block is greater than the maximum cross-sectional area of the first bit of said block. |
