Originally designed for Glow powered aircraft but now also popular for Electric powered aircraft. KAVAN AirWheels have the weight of foam wheels and the strength of conventional plastic/rubber air wheels.

KAVAN pneumatic tires only weigh as much as foam rubber tires and are just
as strong as normal plastic/rubber pneumatic tires.SuperLight Deluxe pneumatic tires have a chrome-plated plastic rim and
longitudinal grooves.
Thanks to a special manufacturing process, the tires have a uniform wall
thickness and are therefore stable to run without bouncing or wobbling.
This results in outstanding directional stability. They are just as
suitable for smooth runways as they are for grass runways.
