They aren't airless, they just don't depend on compressed gas.

- danans 5y agoBy that definition, almost nothing but the vacuum of space is airless. Even a galvanized rubber hockey puck is going to have some amount of air in it. Airless in this case means that they don't use pressurized air for rigidity, and therefore they do not need to be engineered to maintain air pressure, thereby reducing material input, and removing a major failure mode. They are wheel-shaped springs.
