The ground-clearance of this car is higher than any I've ever owned; my Cadillac ELR was much lower and handled snow just fine. I used to daily my Lotus Elise Touring in Denver in the winter (snow on the radiator made for a lot of steam, and the manual recommends removing it of course). I also dailied my SLP Firehawk in North Dakota in the winter as well. In both cases, winter tires are always a must. If you live in a snow-place, it's obvious to get snow tires specifically for that task and temperature. All-Weathers are "No-Weathers" to me, being poor in "all conditions". You wouldn't wear tennis shoes in deep snow. You wouldn't wear snow-boots in 110 deg. F. heat. Obvious, common-sense.
The OEM 19" Pirelli Sotto-Zeroes are acceptable, but I prefer Bridgestone Blizzaks.
