On dry pavement this tire is noisy, but not at all uncomfortably loud, even with the relatively low amount of noise insulation on the Subaru Impreza. The ride isn't very supple, but does transmit some road feel to the steering wheel (a good thing). Sharp bumps seem to be dissipated better than the stock all season tires. Steering responsiveness is much lower than the stock tires, as to be expected from an aggressive snow tire. They have a fairly high limit before they break loose on dry pavement, and are fairly predictable at their limit.
In deep slush, they are very well behaved. The fairly light Impreza used to be heavily affected by slush at medium to high speeds, but these tires clear the slush very nicely.
In light snow (1-3 inches) the tires perform very well. Acceleration and braking is amazing compared to the stock tires, and cornering is even better. At the limit of these tires grip, they react very predictably. Ice traction is also much better than stock. You have to be pretty aggressive to get these tires to slide out of control in light to medium snow.
I haven't had the chance to use these tires in deep snow yet.
