A wheel is provided with a corrosion resistant coating, such as a powder coating. The powder coating of the wheel in interaction with the interior of the tire creates a virtual inner tube for the wheel, thereby improving the air retention characteristics of the wheel and tire assembly. Alternatively, the wheel could be provided a flexibly resilient plastic strip, such as an adhesive backed urethane, to cover the area where the tire is in contact with the wheel.
