Considering that these tires are LRR (low rolling resistance,) the low treadwear and improve MPG they offer is nice and rated high. But due to the hard compound the dry traction suffers and doesn't seem deserving of their high performance title; and they're just about on par with other all season tires in the dry traction category. Wet traction is great and seems better than my last all season tires (Pirelli P6s.)
Snow traction... for a High Performance all season tire these do not fit their title. They seem to lack that certain bite to go through the snow. They've been put through heavy & slushy wet snow, light $ dry snow, and hard packed snow; and these do not excel and just barely get by in snowy conditions.
Overall not a bad tire for commuting, and in that respect they are very capable. But, for spirited driving they do not seem to be very high perform, then again you can't expect to get the best of all worlds in a single tire... Overall I'd say these deserve 7 out of 10.
