An outer wheel, tire and rim, is mounted onto an inner wheel or hub and is adapted for low friction rotation on the hub. An arm is pivotally attached to the inner wheel and carries a receiver for the axle upon which the wheel is mounted so that the axle is positionable over an arc of rotation about the pivot point of the arm. The arm is biased by an elastomeric body so that as the arm moves over its arc of rotation, the elastomeric body is compressed. As the wheel rotates under load, road shocks are transferred to the biasing device which acts as a shock absorber.
