We tested it on the (balding) stock Potenza's in dry weather around 5'C, and I can attest that the Michelins were better even in worse conditions. Better than new Potenza's, or better than any other tire, or how they will wear, I have no idea. But for the stock rubber to be gone in 32,000km (when the rest of the car shows no evidence of hard driving), I'd say these new ones cannot wear any worse.

We have the AS3 on an older MB S550 saloon that does mainly highway. That's a heavy car, and AWD. We get just shy of 50,000 km out of the Michelin's in that application.
