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. A longitudinal lateral sipe edge density for all lateral sipes is greater than 5.5 micrometers/mm.
