Ive run michelin ps since having car now for over 4 years, they are a good tyre but expensive, ive just switched to goodyear F1 asyemetric and personally think they have the edge on the michelins, doesnt seem to be as much flexing in sidewall.
Also from a non scientific test going round a couple of corners with the michelins on it would try to activate esp, on same corners, same conditions goodyears dont. Make of that what you want, but i would think maybe goodyears have the edge on dry grip over the michelin.
