That's hardly any snow at all, you wouldn't use snow chanins for that.
But snow tires on the other hand are quite handy, and indeed mandatory by law in Sweden during winter.
Snow tires with studs is teh #%&*$# when the roads are slippery!
http://en.wikipedia.org/wiki/Winter_tyres Tend to agree, driver education also helps big time. I have winter tyres for my 4x4 and for the last 2 years have been great, this year they havn't been on the car yet. I got a set of Verdstien winter tyres for the wife's car and wow they made a huge diffrence to it.
The video, what can one say, inapropriate speed for the conditions, driving without due care and attention.
