Unfortunately, for passenger car tires, that is only true at slower speeds. RR climbs exponentially at higher speeds. 50 mph seems to be the breakoff point - which is also unfortunately within normal driving speeds.
I suggest you add a note that the RR part is only true below 50 mph and explain what happens to RR at higher speeds.
