yes, use studded tires
I'm a firm believer in studded tires and have had them on all of my vehicles (except when I lived in Southern Ontario, where they are illegal). That includes front wheel drive, rear wheel drive and 4WD.
Here in Newfoundland, the roads range from slushy to icy (very rarely are they merely wet except on the well travelled highways and dry is practically unheard of) throughout the winter and studded tires, combined with all the safe winter driving practices, are the way to go.
As for the wear on the roads, I don't believe studded tires on passenger vehicles has been convincingly shown to be a significant contributor to road wear. Notably, one 18-wheeler probably does more than many (10s, 100s, ??) passenger vehicles to damage to asphalt surfaces. Weight has more to do with real, structural damage than the contacting surfaces. On Prince Edward Island there are weight limits on trucks in the spring when the roadbeds are wet. However, studded tires are legal ... and required ... through the winter months.
I agree with the previous post, that chains are a great idea but the pre-planning and effort required to put them on when you need them means you are less likely to actually use them for anything more than ballast over the rear wheels. Chains are probably overkill for 99.9% of on-road situations anyway. In this case, studded tires are the happy medium.
The legal date is November 1st here, too. However, this year's early snowfall led the government to make an announcement that it was OK to put them on a little early. I don't think everyone was waiting for the government's OK.
