Last night, we had a big dump of snow: roughly 40 cm or roughly 15 inches. Hellish driving through it this morning. Now, we are going to have some freezing rain tonight, which will mean black ice (ice not visible on the road).
There is one place where one should not scrimp: winter tires. Given our road conditions in Canada, I buy good studded winter tires. They are the best for stopping on icy roads. Four seasons tires just do not cut it, and it is not worth risking your life to save money on tires. So, when it comes to driving in Canada, better to either cut elsewhere and save up some money for winter tires, or take the bus.
