The Goodyear Eagle F1 SuperSport RS, Michelin Pilot Sport Cup 2 R and Pirelli P Zero Trofeo R are regarded as three of the fastest road-legal track day tires in the world. To find out which of these three semi slick tires reigns supreme, I've borrowed a 991.2 Porsche 911 GT3 RS, and have use of Michelin's tire test facility in central France to run my own testing program.

Not being satisfied with just running dry handling, I'm going to test the tires in wet handling, dry and wet braking, and of course the all important dry handling, to find out which tire is fastest in which conditions.

Excellent steering precision and feedback. High levels of aquaplaning and low grip in the wet. While the Cup 2 R is now equalled on first lap pace by the new Goodyear SuperSport RS, the longer run pace means its still the best in the category of extreme performance track tires.

2nd: Pirelli P Zero Trofeo R
325/30 R21 3PMSF: no	Test # Result Best Difference % Dry Braking 3rd 48.48 M 43.55 M +4.93 M 89.83% Dry Handling 3rd 64.9 s 63.2 s +1.7 s 97.38% Wet Braking 1st 38.15 M 100% Wet Handling 1st 106.47 s 100% Tire Weight 3rd 53.34 Kg 50.68 Kg +2.66 Kg 95.01% Excellent wet grip, in both wet braking and wet handling. Relatively low levels of aquaplaning. Stable lap times in the dry and easy to drive fast. Relatively long dry braking and relatively average grip in the dry. Rear aquaplaning in the wet. In this size at least, the Trofeo R should be a rival to the Cup 2, not the Cup 2 R. The Trofeo R was slower and softer in the dry, but had much better mechanical grip in the wet. As the lap times were more consistent, this is the type of tire to fit if you plan on doing a lot of track days. Read Reviews
