A pneumatic in-line skating wheel having a tire body and central hub chemically bonded during a polyurethane casting process and further including an annularly encapsulated air bladder centrally spaced within the tire body to provide shock absorption. The bladder in one embodiment is in communication with a valve for inflation and deflation thereof such that the overall tire resiliency may be adjusted, enabling adjustable performance characteristics of the wheel. One embodiment of the valve incorporates a resilient core within a rigid barrel and stretchable to allow an inflation needle to stretch the core and drive a poppet off a seat at the interior end of the barrel.
