Abstract
A tyre with a tread band having a plurality of blocks. The blocks include three-dimensional sipes extending in a direction incident to an advance direction of the tyre. Each sipe separates a block into a first block portion having a first surface facing the advance direction, and into a second block portion having a second surface facing the direction counter to the advance direction. Male/female couplings are provided between the first and the second block portions, the couplings formed by protuberances on the first surface and extending towards the second block portion, and by recesses on the second surface and extending away from the first block portion. The protuberances formed on the first surface have an apex that is spaced apart from the tread surface by no more than 40% of the depth of the three-dimensional sipe, measured at the apex.
