Abstract
A tire tread is provided. The tire tread includes a plurality of tread elements positioned on a tire tread surface so as to comprise a tread pattern. The tire tread also includes a plurality of grooves provided between the plurality of tread elements. A first set of sipes is provided to the tire tread, the first set of sipes extending from a longitudinal axis of the tire tread and toward a first edge of the tire tread at a first non-zero angle with respect to a lateral axis of the tire tread. A second set of sipes is also provided to the tire tread, the second set of sipes extending from the longitudinal axis and toward the first edge of the tire tread at a second non-zero angle with respect to the lateral axis, the second set of sipes intersecting the first set of sipes.
Claims23
A tire tread comprising:
- a plurality of tread elements positioned on a tire tread surface so as to comprise a tread pattern;
- a plurality of grooves provided between the plurality of tread elements;
- a first set of sipes extending from a longitudinal axis of the tire tread and toward a first edge of the tire tread at a first non-zero angle with respect to a lateral axis of the tire tread, the first set of sipes defining a first length from a first termination point to a second termination point;
- and
- a second set of sipes extending from the longitudinal axis and toward the first edge of the tire tread at a second non-zero angle with respect to the lateral axis, the second set of sipes intersecting the first set of sipes, the second set of sipes defining a second length from a third termination point to a fourth termination point;
- wherein each sipe of the first set of sipes has a first depth along the first length and each sipe of the second set of sipes has a second depth along the second length, the first depth being different from the second depth;
- and
- wherein the first depth and the second depth are greater than 50% of a height of the plurality of tread elements.
A tire tread comprising:
- a first set of sipes extending from a longitudinal axis of the tire tread towards a first edge of the tire tread at a first non-zero angle with respect to a lateral axis of the tire tread, the first set of sipes defining a first length from a first termination point to a second termination point, the first set of sipes comprising:
- a first sipe;
- and
- a second sipe positioned at a first pitch distance from the first sipe;
- and
- a second set of sipes extending from the longitudinal axis toward the first edge of the tire tread at a second non-zero angle with respect to the lateral axis, the second set of sipes defining a second length from a third termination point to a fourth termination point, the second set of sipes comprising:
- a third sipe;
- and
- a fourth sipe positioned at a second pitch distance from the third sipe;
- wherein the first non-zero angle is different from the second non-zero angle;
- wherein each sipe of the first set of sipes has a first depth along the first length and each sipe of the second set of sipes has a second depth along the second length, the first depth being different from the second depth;
- and
- wherein the first depth and the second depth are greater than 50% of a height of a plurality tread elements of the tire tread.
A tire tread comprising:
- a first set of sipes extending from a longitudinal axis of the tire tread towards a first edge of the tire tread at a first non-zero angle with respect to a lateral axis of the tire tread, the first set of sipes defining a first length from a first termination point to a second termination point, the first set of sipes comprising a first sipe;
- and
- a second set of sipes extending from the longitudinal axis toward the first edge of the tire tread at a second non-zero angle with respect to the lateral axis, the second set of sipes defining a second length from a third termination point to a fourth termination point, the second set of sipes comprising:
- a second sipe;
- a third sipe positioned at a first pitch distance from the second sipe;
- and
- a fourth sipe positioned at a second pitch distance from the third sipe;
- wherein each sipe of the first set of sipes has a first depth along the first length and each sipe of the second set of sipes has a second depth along the second length, the first depth being different from the second depth;
- wherein the first depth and the second depth are greater than 50% of a height of a plurality tread elements of the tire tread;
- wherein the first non-zero angle is different from the second non-zero angle;
- and
- wherein the first sipe intersects each of the second sipe, the third sipe, and the fourth sipe.
A tire tread comprising:
- a plurality of tread elements positioned on a tire tread surface and forming a tread pattern, one or more of the plurality of tread elements defining a tread element height;
- a first set of sipes defining a first length extending between a first edge of the tire tread and a second edge of the tire tread at a first non-zero angle with respect to a lateral axis of the tire tread, the first set of sipes including a first sipe having a first depth along the length and a second sipe having a second depth different from the first depth, each sipe in the first set of sipes positioned apart from one another by a pitch distance;
- and
- a second set of sipes defining a second length extending between the first edge of the tire tread and the second edge of the tire tread at a second non-zero angle different from the first non-zero angle with respect to the lateral axis of the tire tread, the second set of sipes having a third depth different from the first depth and the second depth;
- wherein the first depth, the second depth, and the third depth are greater than 50% of the tread element height;
- and
- wherein the first set of sipes intersects the second set of sipes.
