Abstract: Embodiments of the disclosure include pneumatic tires having improved snow performance. Said tires include a cap ply extending at least partially across a full width of at least one of the belt plies and having a rupture force greater than 210 N per 15 mm of cap ply width. A shoulder rib includes a compliance groove or sipe extending primarily in a circumferential direction and to a depth equal to or less than 75% of the skid depth. The lateral sipes and grooves are arranged to provide an average lateral feature spacing of less than 15 mm. The average inclination angle for the lateral grooves is greater than 6 degrees in the shoulder ribs and is greater than 20 degrees in the central ribs. A longitudinal non-lateral sipe edge density is greater than 21.1 micrometers/mm 2 . A longitudinal lateral sipe edge density for all lateral sipes is greater than 5.5 micrometers/mm 2 .

Abstract: Particular embodiments of the disclosure provide a tire tread (18), the tire tread including at least one sipe (24) extending into the tread thickness along a depthwise path into the tread thickness away from an outer, ground-engaging side of the tread and to a terminal end. The sipe has a thickness extending perpendicular to the depthwise path, the depthwise path being located midway across the sipe thickness, where a portion of the depthwise path undulates back and forth in a direction perpendicular to the direction of the tread thickness as the depthwise path extends into the tread thickness to form a plurality of undulations (U24), the undulations decreasing in amplitude relative to a centerline of the depthwise path as the sipe extends further into the tread thickness towards the terminal end (26).

Abstract: Embodiments of the disclosure include a pneumatic tire having improved high speed limits while generally maintaining wear, traction, and handling performance. Said tires include a cap ply extending substantially across a full width of at least one of the belt plies and being arranged at least partially within each shoulder, the cap ply forming a layer of elastomeric material reinforced with a plurality of elongate reinforcements spaced apart in an array, the cap ply being characterized as having a rupture force greater than 210 N per 15 mm of the cap ply width. In each shoulder area of said tires, the tread is characterized as being flatter and having a greater tread thickness.

Abstract: Embodiments of the disclosure include pneumatic tires having improved rolling resistance performance. Said tires include a cap ply extending at least partially across a full width of at least one of the belt plies, the cap ply being characterized as having a rupture force greater than 210 N per 15 mm of the cap ply width. Said tires also include an inner layer of elastomeric material free of any elongate reinforcements, the inner layer arranged radially inward from the tread between the tread and any belt plies and cap ply, the inner layer being substantially formed of elastomeric material characterized as having a hysteresis lower than a hysteresis of the elastomeric material forming the tread. Reduced hysteretic belt plies and a compliance groove or sipe may also be arranged within at least one shoulder rib. The tread also include a reduced density of lateral tread features.

Abstract: A tread design for a tire is described herein that has excellent wear properties, hydroplaning resistance, and snow grip. The combination of features also makes it suitable for use in high torque high load conditions found in modern day light truck applications. The tread includes a plurality of tread features lateral sipes, lateral grooves, longitudinal sipes and longitudinal grooves, the longitudinal grooves arranged to form a plurality of ribs, each rib extending annularly around the tread and where adjacent ribs are separated by one of the longitudinal grooves, the plurality of ribs including a pair of shoulder ribs and a plurality of central ribs. At least two of the plurality of central ribs is continuous in the longitudinal direction and are separated by a bridged longitudinal groove. The center section of the tire tread having a higher CSR than the shoulder region of the tire.

Abstract: A tread design for a tire is described herein that has excellent wear properties, hydroplaning resistance, and snow grip. The combination of features also makes it suitable for use in high torque high load conditions found in modern day light truck applications. The tread (18) includes a plurality of tread features lateral sipes (30), lateral grooves (28), longitudinal sipes (31) and longitudinal grooves (24), the longitudinal grooves arranged to form a plurality of ribs (32), each rib extending annularly around the tread and where adjacent ribs are separated by one of the longitudinal grooves, the plurality of ribs including a pair of shoulder ribs and a plurality of central ribs. At least one of the plurality of central ribs is continuous in the longitudinal direction and the elastomeric material forming the tread possesses high compression set allowing the material to plastically deform creating a more rigid tread structure.
