The front wheel used helical springs and hydraulic dampers; the rear axle leaf springs. It was connected on both sides to the Trado-system by which all four rear wheels could be driven. Hydraulic brakes were present on all six wheels. It had been intended to fit bulletproof tyres, but as none were available conventional Dunlop "Trackgrip" terrain tyres were used. Bulletproof tyres would have slightly reduced the maximum speed. Special armoured hubcaps protected the hubs. As the sloped armour caused a considerable overhang at the nose of the vehicle it was equipped at this point with two rather large unpowered auxiliary wheels, to prevent ditching. If ditched or stuck in soft soil, freeing the cars could be facilitated by two detachable boards, attached on each side above the rear wheels, which position also reduced dust clouds while driving and covered what otherwise would have been a very conspicuous light-dark contrast between the angled upper hull and the large shadowed part below the rear fender. There were two fuel reservoirs, a main and a reserve tank, below the floor plate of the main compartment, holding a total of 85 litres of petrol; this allowed for a range of about 200-225 kilometres. The numbers given by some sources of a hundred litres and a range of three hundred kilometres, are incorrect.
