Bought these to go on my girlfriend's infiniti. Replace some old Goodyears. I'm one for spirited driving and these tires hold up well for that. dry grip is solid and it takes some pushing to get these tires to their limits in a big sedan. very stable overall, but there's a very slight hesitation when doing sudden course correction (did a quick homebrew autocross when the tires were new). Most people won't notice it but i'm used to driving an Mr2.
Wet grip is great for an all season and im constantly impressed by how stable it is and its resistance to sliding. You can get it to slide if you push too hard, but i can take the same turns comfortably at 80% speed wet vs dry. wet braking is a little less impressive, as it will engage the ABS quickly if you stab it too hard, but generally good braking performance in light and heavy rain.
Snow/ice performance is average for an all season, Light snow being significantly better than deep, but i've only needed to dig myself out once this winter, so from standstills/parking it gets you going just fine.
I drive with traction control off most of the time and i have to actually try to lose the rear end on anything other than ice. very predictable when a slide begins as well.
For the record, i live in Chicago, so i've seen wet, dry, snow and ice in the same week.
Rides a little harsh and drones a bit at 70mph, but those are acceptable trade-offs for a the perforamnce/price envelope this tire gives.
