the pzero-C is an older tire, too, unfortuantely, where the R-1 is only 2 years old. either way, they article said themselves that the wornd conditions of the R-1 gave it an edge. go ask around the the petit lemans, and see what tires they run. Pirelli, michelin, or bridgestone.
..And the tire rack used the "rosso" which is, incredibly, a tuned down version(for more ride comfort) than the pzero asimytrico, and S-03 is one helluva tire, but it doesnt have the progressive feel of the Pzero. I've been in cars with AVS sports, Pzeros(rosso and asymetrcio), pilot sports(ugh.), and goodyears.
goodyear was the suckiest. the michelin pilot sport doesnt ahve a good enough tuyrn in feel for me, due to a relative flexibility of its sidewall.only problem I had with AVS sports is their noise level...
anyways, Pzero is where people comapre tires to, and that speaks for itself. all in all, I love them, and its hard to find anything to beat them overall(except price.ugh these are the expensive)
anyways, good atricles man!also, race tires do better when worn...not new
