I replaced the Continental ProContact's immediately (less than 30 miles driven) with the Vredestein Wintrac Pro - first real test was last night driving through Connecticut to New York City in white out conditions.
The roads were bad and I can definitely feel the AWD constantly adjusting to the traction, but the car performed ..very.. well. We had stopped at the Darien Supercharger as it was coming down very hard and by the time we were done there was about 1" of snow on the ground and no plowing so I tried to get the car to spin out in the empty parking lot but even though the back would pull a bit out on a turn it pretty quickly corrected.
My biggest fear was regen braking and slowing the car down but I didn't feel the car loosing control when lifting from the pedal and there were a number of rapid deceleration moments as cars spun out in front of us or we'd take a on-ramp from the LIE to BQE to see two cars blocking the opposite lanes, one trying to get chains on the car and the other taking a breather of spinning out and hitting the onramp wall.
Today I had to move the car around (street parked in NYC) and while I got stuck briefly cresting a snow berm that was over a foot deep I was able to use the Slip Start functionality and rocking the car to get it unstuck.
My biggest complaints are that the wipers are a bit disappointing and there's no heat around on the sensors to keep them clear, or cameras.
The one outstanding question is whether the NYC sanitation trucks throwing rock salt will damage the paint. I had the bottom of the doors and fenders/bumpers wrapped in PPF and the car coated in ceramic, but I just don't trust the Tesla paint to perform well.
