A tire having a tread with a plurality of blocks 12 provided with at least one sipe 22 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 38 and at least one second layer of material 40 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 22 and the grooves separating the blocks are formed entirely in the first layer of material 38. Laterally on each side of the complex sipe, the second layer of material 40 extends, when viewed in transverse section in the block, beyond the bottom 30 of the complex sipe in the direction of the contact face of the block.
