For many years I used Bridgestone Blizzaks, which perform very well in ice and snow. But for my new all-wheel drive Audi, I wanted winter tires that handled better on dry pavement. The Michelin Xi3 was said to almost equal the Blizzaks on ice and snow but be less squishy on dry and wet pavement, so I went with the Michelin.
Shortly after mounting them I drove to the NH White Mountains and took part in a winter driving school. For two days I practiced slalom and skid-pad maneuvers on ice and packed snow. The Michelins were exemplary here, and the instructors were very impressed. While other cars (mostly AWD Audis) were sliding into snowbanks left and right, my allroad with the Michelins stayed in control, accelerated and braked very well.
The claimed performance on dry roads was also seen - unlike the Blizzaks, the Michelins don't howl and they felt very much like good all-season tires on dry pavement, with a confident feeling. Very impressive.
