Transport Canada, the Automobile Protection Agency (APA) and the Rubber Association of Canada (RAC), have created a series of videos on the importance of winter tires.
In video #4, braking and negotiating curves are demonstrated between a rear wheel drive truck and a sedan, comparing the performance between winter tires and all season tires.
We see here that a sedan with winter tires performs better than the truck with all seasons.
And again, the difference in performance between having four or two winter tires.
You may not qualify for the Winter Tire Discount from your insurance company if you only have two winter tires.
