Well you also have to realize that there is some amount of slippage involved in grip driving, no matter how imperceptable it is, whether it be a couple of inches, or less than an inch, it's still there (even on F1 cars, where it is fractions of an inch). Back in the early days of racing they had very narrow tires, infferior rubber and no aerodynamic downforce, so this slip-angle was much more pronounced than it is today with wide tires, high-tech rubber and treads, and aerodynamic downforce (or at least zero lift). If you don't believe me do an internet search on Tazio Nuvolari (I search for four wheel drifting and come up empty most of the time, but Nuvolari used this technique and won Formula 1 championships against supperior cars, his most notable victory was at the german GP on the Nurburgring in an outdated and thoroughly inferior car). It should be noted that in this type of drifting, the tires not drifting because of the loss of traction, it is the natural consequence of using the maximum GRIP of your tires.
