  "textContent": "A tire having a tread with a plurality of blocks provided with at least one sipe extending from the contact face of said block, and having a width that can vary in the direction of its depth, and known as a complex sipe. The tread has a first layer of material and at least one second layer of material radially on the inside of the first layer, the first layer being formed in a first rubber composition and the second layer being formed in a second rubber composition different from the first composition. The complex sipe and the grooves separating the blocks are formed entirely in the first layer of material . Laterally on each side of the complex sipe, the second layer of material extends, when viewed in transverse section in the block, beyond the bottom of the complex sipe in the direction of the contact face of the block.",
