It really depends. Say you break your arm, then learn Japanese during the 8 week layoff, then make a killing following the Nikkei in the fallout, then it all works out in the end as you can buy all the studded tires and GI Joe with the Kung Fu Grips that you want.
If you don't want to break a limb go with the front, as Sir Jake A Lot suggests, I would imagine. Then throw whatever has the deepest treads on the rear? Though if you hit ice, that rear end will fly out to 90 degree angles in a flash. I've had that happen before and it can be fun in its own way, but also frustrating when you go down hard on the ice. I find that going down on the ice is more fun if you've got some speed.
