nonpneumatic
Not filled with air
Nonpneumatic describes tires or wheels that don't use air pressure for support.
Traditional pneumatic tires are inflated with compressed air; nonpneumatic alternatives use solid rubber, foam, or structural designs like honeycomb patterns to bear weight without risking flats: The lawnmower has nonpneumatic tires that never need inflating.
