Instead of via air, the new tires stay flexible via spokes made out of a thermoplastic resin (a polymer compound that can be shaped while heated and remains fixed when cooled). Features:
- Completely recyclable (one of the goals of the project).
- The tires can carry loads of up to 150kg. Quoting Inhabitat :
So far, the company has been testing the airless concept on a small one-seat electric vehicle [weighing about 50kg], and it plans to continue developing the technology for wider commercial use.
- Remaining challenge: preventing objects from getting caught in the spokes.
- Advantage for cars: no need to carry a spare tire, resulting in space and weight savings.
