Dunlop M3 snow tires and traction control got me through a Nebraska winter last year and hopefully this year too. If it's over 6 inches I won't go out in it though, too many drifts and the low clearance on the car would be a problem.

 

I just picked up a set of stock 17" bullits take offs from ebay for 374.00 shipped. And ordered up a set of goodyearGoodyear Ultra Grip GW3
The 18" fanblades will be the only thing going into storage for the winter.

Ive had the Ultra Grip GW2's on my t-bird and it made a difference.
I went with 17"(235/55r17) snows vs 18"(235/50r18) to help with the cost, and narrower the tire the better for snow traction. And sure will be nice not having to change over the tires/wheels twice every winter. And keeping the fanblades in good condition.
