An off-road tire tread for a tire includes a series of cavities extending into the tread surface, each cavity defined by sidewalls extending from a tread surface to an inclined bottom cavity surface, the inclined bottom cavity surface extending from a relatively deep leading cavity end to a relatively shallow trailing cavity end. The cavities are directionally oriented to operationally initiate contact with a ground surface at the leading cavity end and form a repeating circumferential pattern along a circumferential extent of the tread surface. The tire tread further may include one or more lug protrusions between each of the cavities extending outward from the tread surface. |
