摘要
The tyre comprises a tread comprising 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 varies in the direction of its depth, referred to as a complex sipe. The tread comprises a first layer of material (38) and at least one second layer of material (40) radially on the inside of said first layer, the first layer being formed from a first rubber composition and said second layer being formed from a second rubber composition different from the first composition. Said complex sipe (22) and the grooves separating the blocks are entirely formed in the first layer of material (38). Laterally on either side of said complex sipe, the second layer of material (40) extends, in a cross-sectional view through said block, beyond the bottom (30) of said complex sipe in the direction of the contact face of said block.
