Used these tires in size 15" the rest of last season (changed shoes in early spring from Nordman 7 due to the desire to buy something decent while I can). After changing shoes, you immediately feel the difference for the better on all types of coverage - from asphalt to ice inclusive. Also compared with Goodyear Ice Arctic (studs) on another car for an hour on the same route - also a difference in grip in favor of Michelin. Inferior to Goodyear only in rowing ability in loose deep snow. = I think that good winter tires are more important than good summer tires - because in summer it is problematic to drive at the limit of the coupling properties of tires, there is nowhere (and even 1% of drivers can do it). And in winter all sorts of situations are possible .
