But on a 6500lb SUV, do I really need "stickiness"? What we found over the years was that the snow tires wear down nicely by early summer and make an excellent "all season" tire during the summer/fall. The deep grooves enable good rain channels, and the base tread is much harder than you'd think. We take the Rover to Vegas often and the car/tires see temps of 120 degrees in the summer and have plenty of grip at that temp....
This will be our 6th year with this model, and it just works for us. The only challenge has been finding the right winter tire with a 90 degree tread angle. The M+S Pirelli's and Michelins both didn't work well in deep snow. The Blizzaks have been amazing.

You have some brains. I would do the same if I lived there.
In michigan I'm thinking of just getting 4 new rims and swapping to those snows you have in december-april then go back to the Scorpian zeros for summer time.
