Tire Question -- All Seasons Vs. Snow Tires?

[ezdays]

I saw this thread and had to ask myself, "do they really make tires out of snow?" We have, "all season" tires here in Arizona, they're kinda made out of a blend of wood, ground cactus and steel. They don't ride really good, but they won't melt and stick to the road like them there rubber ones do. :? It really doesn't matter what time of the year it is, that can happen summer or winter, that's why we call them "All Season tires"... But tires made from snow, I wouldn't give them much hope, even up north... Or am I reading this wrong? You'll have to excuse me if I am, I've been living out here in the desert just a few years too long, and we've just had one of the hottest summers ever and I think the heat kind of baked my brain a bit.
