An ASW is shown with weathering steel treads. On the left, the sidewalls are removed to illustrate how it works. On the right, it is shown in cutaway section with sidewalls on:

 

The ASW is laterally rigid. That ensures extreme lateral stability and cornering capability. Its axial and circumferential stiffness an deflection capacity meets or exceeds that of the inflated rubber tire it replaces.

Some tested wheels and wheel configurations are shown in this slideshow (opens in same window, click back arrow to come back):

Coreten weathering steel treads:

 

The steel tire deflects under load at least as much the rubber tire does and the treads deform at least as much as the rubber treads deform. Thus the steel tire ensures the same or better riding quality as the rubber tire. For improved performance and comfort however, the steel tire is configured to have larger deflection and deformation capability.

Our individually replaceable bolt-on steel reinforced tread blocks (gripper bars) are made of hard rubber to last for 3-5 years under harsh conditions in heavy work load:

“You never change things by fighting the existing reality,” Bucky Fuller once said. “To change something, build a new model that makes the existing model obsolete.” The ASW is it. Its time just has come. It can reduce mining overall expenses by 5%. A win for the mine, the consumers, the environment and the public.
