First impression: nothing special on dry/wet. Can not comment on stability - got this 2 sizes narrower one size smaller rim and one size taller side wall than standard...
Light snow ... nothing special, better breaking than forward traction
Heavy snow: Holly...! yesterday we got several inches, but it was impressive when, without any shoveling, i got out from the parking lot trough a solid 100 yards of 15-20 inches of blown snow just by backing up and going forward again 3 times - did a super snow angel of my car, it even had the impressions of the headlights washers in there- it was so high.
How do they do it? I guess is the super-soft compound - had erasers that were stiffer than it... Noise is not that bad,actually, they make less noise than the Bridgestone potenza g009 that they replace, much less
