    Abstract: FIG. 1 is a perspective view of the new design for a tire tread, it being understood that the tread pattern repeats circumferentially throughout the outer circumference and shoulder of the tire;
    FIG. 2 is a front elevation view thereof; and,
    FIG. 3 is a side elevation view thereof, the opposite side elevational view being a mirror image thereof.
    The dash-dash broken lines depicting a tire sidewall and inner bead are included for the purpose of illustrating environment and form no part of the claimed design.
    The dash-dot broken lines define the bounds of the claimed design and form no part thereof.
    The stippling shown in the drawings represents the approximate three-dimensional contour of the design, and is not intended to indicate surface decoration. The dark stippled surface shading represents the recessed portion of the tread grooves.

    Abstract: A self-propelled, one-wheeled vehicle may include a board having two deck portions each having a concave front footpad configured to receive a foot of a rider, and a wheel assembly disposed between the deck portions. The concave front footpad has a rider detection sensor in the form of a membrane switch conforming to the shape of the footpad (e.g., facilitated by one or more slots formed in the membrane switch). A motor assembly drives the vehicle in response to board orientation and rider detection information.
