Abstract: The tread has a total width W and two main grooves. The main grooves divide the tread into a middle region and edge regions. The middle region has an axial width Lm that is 45% to 70% of the total width W. The volume void ratio of the tread when new is less than 17%. An internal surface extends parallel to the tread surface when new and is in contact radially with the innermost points of the deepest main grooves. The middle part has a plurality of transverse sipes, each of which has a depth at least equal to the depth of the main grooves. The transverse sipes open into the main grooves. The middle region has a volume void ratio when new that is less than half the total volume void ratio of the tread, and at least one circumferential channel appears when the tread becomes part worn.

Abstract: A pneumatic tire has a unidirectional tread pattern. On each side of the tire equator, there are a circumferential groove and main oblique grooves extending form the tread edge to the circumferential groove while inclining to the intended tire rotational direction and gradually decreasing its inclination angle with respect to the tire circumferential direction. The inclination angle of the main oblique groove measured at the tread edge is 60 to 120 degrees. The width of the main oblique groove is gradually increased toward the axially outside from the circumferential groove. The width of the circumferential groove becomes narrower at heel-side ends of shoulder blocks than at toe-side ends of the shoulder blocks. The shoulder block is provided with an auxiliary oblique groove extending from the main oblique groove toward the intended tire rotational direction and terminating without reaching to the next main oblique groove.

Abstract: A tread having a plurality of grooves formed on each half of the tread on each side of a midplane X-X′, each opening axially to the outside and extending axially towards the midplane X-X′ so that the plurality of grooves forms a first pattern in the overall shape of a V pointing in a groove direction Xr. The tread includes a plurality of sipes. From a certain degree of wear onwards, all or some of the sipes become enlarged forming cavities extending in an oblique direction forming a second pattern in the overall shape of a V pointing in a cavity direction Xc. Each of these cavities opens into just one of the grooves of the tread, the plurality of grooves forming, at this level of wear, the same first pattern.
