Reinventing the Wheel Again, Once More

Tires and wheels that can change configuration to suit the purpose at hand, might come in handy. Modern tires that can assume only one shape are of limited use in an all-purpose, amphibious vehicle.The wheels / tires shown above are capable of changing from conventional round tires, to a stepped snow tire shape, to a water-wheel configuration. That should prove useful, should you wish to cross the river without a bridge.The system above is known as the intelligent wheel system. Its 3 configurations can serve well on the highway, on snow - mud - or sand, and in the water.
