In more recent years, I have always gone to two sets of wheels and tires: Summer and Winter. Both are purposefully designed to react to the two different environments.
It costs more, but I don't find All Season tires to be effective at the end of their range - i.e. they are okay, but not great, in any season. Best to have tires specifically oriented to the two distinct/different driving situations. And you don't subject your nice Summer rims to salt, sand, snow, etc.
That's what I've done with the Smart for, I guess, 6 years now. The first year I put the WinterContacs on, it was amazing. It was unstoppable. What happened is I found myself putting the winter tires on sooner and leaving them on longer, because of the way they handled
Last summer, just as I finally decided to buy some new summer tires, a fellow Smart owner raved about the Quadtracs. Being a fan of Vredestein since well before Sprints were "Classic," I decided to give them a try. The transformation of the Smart was incredible. I told my friend that the Quadtracs increased the joy of driving equal to the amount that replacing the OEM shocks and struts with Bilsteins did. Cornered better, rode smoother, etc.
The true test will be when the snow flies whether I can make it up the 8% grade to my complex. (Chains are under the passenger seat, just in case.)
As for the Spyder, I think I'm going to stick with the cheapo winter tires until I can raise my car enough to avoid the negative camber I have now to clear the fender. Unfortunately, my old car doesn't have adjustable spring plates like the newer ones do, so I've got to switch them. I'll think about SporTracs after I've worn out the front tires, too.
