Airless tires, non-pneumatic tires (NPT), or flat-free tires are tires that are not supported by air pressure. [1] [2] [3] They can be used on small vehicles such as ride-on lawn mowers and motorized golf carts. They also are used on heavy equipment required to operate on sites where risk of tire punctures is high.
