Abstract
Official abstract text for this publication.
A tire for an autonomous vehicle includes a pair of sidewalls that extend to a ground-engaging tread. The tread includes a plurality of hexagonally-shaped tread elements, and the tire includes an outer diameter that is at least four times larger than a width of the tread. Selected hexagonally-shaped tread elements may be formed with features to increase traction on icy roads.
First claim
Opening claim text (preview).
What is claimed is: 1. A tire for an autonomous vehicle, comprising: a pair of sidewalls extending to a ground-engaging tread; the tread including a plurality of hexagonally-shaped tread elements, wherein each hexagonally-shaped tread element includes: a center element formed in a hexagonal shape; a plurality of trapezoidally-shaped components surrounding the center element, the trapezoidally-shaped components being disposed about the center element; and wherein the trapezoidally-shaped components form a hexagonal shape about the center element; and the tire including an outer diameter at least 4 times larger than a width of the tread. 2. The tire for an autonomous vehicle of claim 1 , wherein the outer diameter of the tire is at least 4.5 times larger than the width of the tread. 3. The tire for an autonomous vehicle of claim 2 , wherein the outer diameter of the tire is about 718.8 millimeters and the width of the tread is about 154.9 millimeters. 4. The tire for an autonomous vehicle of claim 1 , wherein the plurality of hexagonally-shaped tread elements are distributed circumferentially about the tread in laterally-extending rows. 5. The tire for an autonomous vehicle of claim 4 , wherein the plurality of hexagonally-shaped tread elements of the laterally-extending rows alternate with one another in an offset manner. 6. The tire for an autonomous vehicle of claim 1 , wherein the hexagonally-shaped tread elements are defined by sipes. 7. The tire for an autonomous vehicle of claim 6 , wherein the thickness of the sipes varies to form a plurality of linked star-shaped patterns. 8. The tire for an autonomous vehicle of claim 1 , wherein the tread further comprises a plurality of non-continuous circumferential grooves. 9. The tire for an autonomous vehicle of claim 1 , wherein the tread is formed without continuous circumferential grooves. 10. The tire for an autonomous vehicle of claim 1 , wherein selected ones of the hexagonally-shaped tread elements are formed with features to increase traction on icy roads.
