Well, the snow was a loooong time coming, but as it happened, I finally got to test these tires in something resembling winter conditions today. Booked the day off work to take my Mom-in-law to some medical appointments, then ran a bunch of errands. All through some consistently heavy snowfall combined with very high winds. I was on the QEW, 403 and 407 highways, dealing with everything from hard-packed snow, slush, drifting snow - pretty much the full parade except for ice.
I am seriously impressed. These are not top-tier snow tires by most reckonings, but I can hardly imagine how they could have done better. In buffeting cross-winds on greasy highways, the Sonata felt utterly planted. I never had any complaints about the grip of my previous Pirelli Winter 210 Snowsports - they pulled me through some really hairy trips. But these are better. Pulling out of the center lane where the majority of cars were rolling slowly nose-to-tail on the most cleared pathway, the car traversed the snow-ruts without a squirm or wiggle, and pulled easily to pass in the not-nearly-as-barren left lane. I saw 4 vehicles in the ditch during the day - Infiniti FX, Toyota Highlander, Ford Edge, and another CUV / SUV that was too smashed up along the guard rail for me to tell. Safe bet that not one was riding on snows.
The one downside I noticed at the beginning has remained: these knobby treads bring increased rolling resistance that in turn exacts a noticeable penalty in fuel consumption. I'd now peg it at a full liter per hundred worse in highway consumption. I'm sure others - particularly the performance-oriented winter tires - can do better.
The only really scary moment of the day happened when I was in the school parking lot waiting to pick up my daughter. I was parked along the curb near the entrance to the lot, and observed this &^%#ing moron in a black F150 blasting down the road, fishtailing like a fool, going way too fast for what little grip he had. Sure enough, he turns into the school parking lot carrying too much speed and gets damn near completely sideways, missing my fender by what had to be less than a foot. Jackass.
Anyway - colour me happy with the purchase.
