I was nervous all day today at work as I watched the snow piling up. I hadn't been out in anything more than an inch or so. I was expecting the worst, since I have the stock tires on my smart.
By the time I left work, there was 4 inches or more on the ground. Quite frankly, I was very impressed. I had no problems at all. I drove very slowly, and put into practice all the snow driving techniques I learned 27 years ago in high school driver ed class (Thanks, Mr. Cinelli!). The traction control was working overtime to keep everything stable. The smart handled FAR FAR better than my last car (Ford Focus). Now that I know it can handle 4-6 inches very well, I will not be getting snow tires. If there is more than that on the ground, the smart will stay in the garage.
