Well, basically I found out that there are 4 levels of regulations:
1: Carry Chains or Traction Tires
2:Chains (required for 2WD and/or certain traction tires) or Traction Tires (AWD) required
3: Chains required on all vehicles
4: Road closed to all traffic
So, it seems like I would have to get non-sport wheels and dedicated snows even to use chains, because I can't keep the Sport Wheels and use chains.
So, it looks like Winter Wheels for me!
