Their conclusion:
"Summary
With tire manufacturers' varying product cycles, a matchup as exciting as this is a rare occurrence, and these three tires did not disappoint. While access to the latest technology meant the two newest tires had the advantage in some respects, all of them are sure to satisfy enthusiast drivers of high performance vehicles.
The Michelin Pilot Sport 4S performs all the tasks expected of a Max Performance Summer tire at a very high level. From its athletic and composed nature on the road, to its best-in-test dry track figures, to its easily accessible performance in the wet, the Pilot Sport 4S really is the complete package. Continental's ExtremeContact Sport presents a compelling option, as well. Its behavior on the road is eager and lively, if not quite as refined as the other two tires. Objective wet cornering and stopping figures for the Continental are top-notch, but with a relatively narrow window that makes it a little harder to wring out every last drop of performance on the track. The Pirelli P Zero (PZ4) delivers a luxuriously sporty experience on the road coupled with a balanced and easy-to-drive nature in the wet or dry on the track, with traction levels that are slightly behind the Michelin and Continental in both aspects."
