Michelin Power SuperSport

Replacing the Power One Street (basically a street/track-day version of Michelin’s Power Race DOT racing rubber), the new Power Supersport uses the latest generation of compounds developed from the company’s extensive participation in the FIM World Endurance Championship. The Power Supersport also employs the same rear tire construction as the Pilot Power 3, with the harder compound extending underneath the softer compound on the shoulders for better support and stability under aggressive cornering. The same 25/50/25 soft/medium/soft compound spread across the front and rear tread profile is used as well, which is a marked difference from the Power One Street’s 37.5/25/37.5 front and 12.5/75/12.5 rear compound distribution.

The Power Supersport’s tread pattern is similar to the Power One, but with slightly more siping in the center and middle portion of the profile’s shoulder, giving the Power Supersport a 7.5 percent void ratio (the percentage of tread siping across the tire’s complete profile face) compared to the Power One Street’s 5.0 percent. This is intended to work with the Power Supersport’s new compounds to make for improved tread longevity as well as overall grip compared to competing brand’s track-day tires.
