The official name of 101 Forward Control is derived from the vehicle's wheelbase, and the position of the driver, above and slightly in front of the front wheels which used a fairly large 9.00 × 16 inch tyre. To cope with the extra height above the ground, the wheels feature an unusual feature for a Land Rover (but used for many years on the much older and similar Mercedes Unimog S404); a flange around the centre of the wheel has an embossed tread pattern forming a step for the crew when entering the cab, named a wheel-step.
