Tyrell Cosworth P34
Six wheeled F1 car

Patrick Depailler driving the Tyrell Cosworth P34 six wheeled F1 car at Monaco with the bodywork around the cockpit removed. The car used four specially manufactured 10-inch-diameter (250 mm) wheels and tyres at the front, with two ordinary-sized wheels at the back. Contrary to popular belief, the idea of the smaller front tyres was not to have a smaller "frontal area" to reduce drag, as the frontal area was still determined by the width of the standard-sized rear slicks. In fact, the six-wheel design reduced the lift caused by two larger front wheels, improving frontal downforce, increased the total contact patch of the front tyres and created a greater swept area for the brake discs.
