Abstract
A wheel with adjustable radius or tread firmness including a hub assembly, primary spokes, a suspension assembly positioned at the outer end of each primary spoke, and treads attached to the outer end of each suspension assembly. The hub assembly includes a radius lock and a tensioner lock. When each is in a locked position, the radius and tread firmness of the wheel remains constant. When the radius lock or the tensioner lock is in an unlocked position, the radius or the tread firmness, respectively, is adjusted by rotating the wheel relative to internal components of the hub assembly. This relative rotation adjusts the tension on internal cords to adjust the length of the primary spokes or flexibility of the suspension assemblies, respectively. Optionally, secondary spokes may be positioned between each of the primary spokes and the suspension assemblies. The radius and tread firmness is adjustable under a load.
