Tire Having Grooves Comprising Sipes And/Or Other Cross-Groove Negative Geometry

A tire, comprising:

• a tread portion comprising at least one groove having a groove base,
• wherein the groove base comprises at least one cross-groove negative geometry comprising:
• a plurality of a first type of cross-groove negative geometries configured as group and separated by a predetermined distance;
• and
• a plurality of a second type of cross-groove negative geometries configured as a group and separated by a predetermined distance,
• wherein the group of the first type of cross-groove negative geometries and the group of the second type of cross-groove negative geometries are provided alternately in a circumferential direction of the tire in the same groove, and separated by a predetermined distance.

A tire, comprising:

• a tread portion comprising at least one groove having a groove base,
• wherein the groove comprises at least one cross-groove negative geometry comprising:
• a plurality of zigzag sipes configured in a group, wherein the plurality of zigzag sipes geometries is separated by a predetermined distance;
• a plurality of straight sipes configured in a group, wherein the plurality of the straight sipes is separated by a predetermined distance;
• wherein the group of the zigzag sipes and the group of the straight sipes are provided alternately in the same groove and separated by a predetermined distance.
