After claiming pole position for the German Grand Prix, Pironi was also busy testing a new-composition Goodyear rain tyre (under the guidance of Mauro Forghieri) in untimed practice. The "new-spec" Goodyear rain tyres proved to be very successful, with Pironi lapping up to 2.5 seconds faster than newly recruited teammate Patrick Tambay driving the sister Ferrari. (Pironi: 2 min 10.9 sec, Tambay: 2 min 13.4 sec)
