In the August Road & Track, the new Ferrari Superamerica, with a 532 HP V-12, is shod with Potenza RE 050 tires, just like our newer S2K's. A lot of this has to do with the tight relationship between Ferrari and Bridgestone in Formula 1 racing but I sure feel like we are in good company !!!

 

Moving to the Tire and Wheel forum.

 

They're not the same tire. Ferrari runs the A version. The S doesn't.
