Excellent tire. As a summer tire I normally use them from end of March to mid-November since here in Central Europe we usually have Novembers with no freezing temperatures so a summer tire can perform relatively acceptable down to 7-10 degC. These tires gives confidence and peace of mind, good grip, very good comfort, low noise, short braking distances, very good handling. This November is colder than usual and under 4-5 degC the tire begins to show weaknesses as the compound is getting harder in cold. Noise increases and looses a certain amount of grip that warns you it's time to change. Still, runs safe just you get the feeling of these are not the circumstances the have been designed for.
The only weak point is the wear. Two seasons (20.000+ kms) and more than half of the tread went away. So I expect 30-35 k kms as lifespan. My former Goodyear lasted longer.
