Abstract: A tire (10) includes a stiffening structure (50) comprising stiffening elements (52) anchored in the crown (12) and extending into the toroidal cavity (35) between a radially inner anchor point (54A, 54B) and a radially outer anchor point (56A, 56B). The tread (14) has a profile height and comprises a plurality of ribs (102, 104, 106, 108, 110), two adjacent ribs being axially separated from each other by a main circumferential cut-out (112, 114, 116, 118) having a depth greater than or equal to 50% of the profile height. The radially outer anchor point (56A, 56B) is aligned with one of the ribs (102, 104, 106, 108, 110).

Abstract: The aspects disclosed herein relate to a tread for a tire including at least one block of rubbery material of width W and length L with L»W. This block extends in a circumferential direction (X) when the tread is mounted on the tire, the block including a contact surface intended to come into contact with the ground and a first lateral wall and a second lateral wall delimiting this contact surface. The block further includes a plurality of sipes opening onto the contact surface of the block, with each sipe extending over the contact surface in an oblique direction opening onto the first lateral wall and onto the second lateral wall, the sipes of the block being oriented in the same direction. The sipes are distributed over the contact surface of the block in such a way that when one sipe reaches the second lateral wall another sipe starts out from the first lateral wall at the same circumferential level (N) on the block, and each sipe includes at least two parts.

Abstract: Disclosed herein is a tread for a tire. The tread includes at least one elongate block of rubbery material of width W and length L with L>>W. This elongate block extends in a circumferential direction (X) when the tread is mounted on the tire. The elongate block includes a contact surface intended to come into contact with the ground and a first lateral wall and a second lateral wall delimiting this contact surface. The elongate block includes a plurality of sipes opening onto the contact surface of the elongate block, with each sine extending in an oblique direction opening onto the first lateral wall and onto the second lateral wall. The sipes are distributed over the contact surface of the block in such a way that when one sipe reaches the second lateral wall another sipe starts out from the first lateral wall, at a same circumferential level (N) on the elongate block. With the sipes delimiting sub-blocks in the elongate block, at least two of these sub-blocks are configured differently in the tread.

Abstract: The tread has circumferential grooves delimiting intermediate and edge parts and formed so as to be present at least until a tread wear limit is reached. The tread also having a tread surface with at least one tread wear indicator formed in a circumferential groove. The tread comprising on its edge regions a plurality of transverse cuts that have depths suited to be present down to the tread wear limit. Each transverse cut is formed of a first part opening onto the tread surface when new and extending towards the inside of the tread by a void part forming a channel of mean width greater than a mean width of the groove. The channel forms a new transverse groove after a predetermined amount of part wear. A cross section of each channel increases when progressing along the cut axially from the inside towards the outside of the tread.
