I have two dedicated sets of wheels and tires, and would never only run on one set year round. End of story. When Fall comes I'll retire my RE-01R's and throw on my other wheels (this years winter tires have yet to be bought) and rock em til snowboarding season is over. If you drive anywhere near the mountains, I wouldn't even think twice about all seasons. The way I see it, if you're semi-comfortable with driving in the snow all seasons will probably be good enough for you to get around, however I like the added safety margin of being that
much more able to avoid accidents in the snow. I don't worry about myself as much as the other idiots on the road, and being able to get out of their way is priceless to me.
putting the summer tires back on in the spring time and hittin corners is pretty gratifying too
