Abstract: An agricultural implement includes a tool bar and at least one row unit carried by the tool bar. Each row unit includes a furrow opener arrangement with a gauge wheel. The gauge wheel includes a rim with an outer periphery and a tire mounted to the outer periphery. The tire includes an outer shell formed from a first resilient material and an inner core formed from a softer second resilient material. The outer shell is positioned radially outward from the inner core and axial outward from axial ends of the inner core. The inner core is mounted directly on the outer periphery of the rim and defines an annular hollow core therein. The tire is structured and arranged such that the softer inner core, the annular hollow core and the harder outer shell coact to provide good wear, good shock absorbance, and good mud shedding capabilities.

Abstract: An in-line skate wheel including a hub that positions and supports a bladder generally about the center line of the hub. The wheel hub comprises an inner surface forming a bore for receiving a wheel axle, an outer circumferential surface spaced from the inner surface and first and second edges. The hub also comprises a center line evenly spaced from the first and second edges of the outer surface. Contoured positioning tabs are located along the circumference of the outer surface and are alternately spaced on opposite sides of the center line to receive and retain the bladder therebetween in order to position it about the center line and support it during the use of the wheel.
