This time came the big hills around Portland OR. We have several subdivisions built on Bull Mountain that have numerous winding, hilly streets.
Most of those streets were covered with snow-swept ice, occasionally sprinkled with a few cinders. Some hills approach 20 - 25 degrees.
  
One hill's lack of traction had sent a Jetta and a small MiniVan down their slopes. A number of FWD cars were spinning wheels as they tried to get going.
  
The XT with Nokians, in all but one case, just went up and down the hills. As before, speeds had to be kept low, but the XT stopped and restarted on any hill, and stopped when going down the same hills. The worst case was when the ice was wet - the ABS definitely kicked in for those braking situations. Accelerating, I did not see any VDC/TC warning lights but felt some of the wheels alternating traction. There was little hesitation and no violent spinning of wheels.
 
Only time the XT lost traction was when it was bounding/turning over a small hill at 5-10 mph. Loss of weight allowed tires to drift momentarily.
 
Overall, WRG2's seem to work

That's interesting. Perhaps the tires weren't spinning due to traction control? The Michelin Ice Xi2s are one of the best if not the best studelss tire out there for ice. I was doing some more starting and going on ice today and my tires were spinning, irregardless how easy I was on the accelerator. I wish I could test drive these tires going up a snowy or icy hilll; however, my Mazda3 does not have traction control. I doubt it would make it.

Yep, it's the ice... I agree, as it is snowing over the top of these icy streets here in Spokane

It's interesting to watch that video and notice how some cars have no trouble at all. I'm wondering if we are seeing different levels of driver skills, since it didn't look like all the "successful" cars were AWD types.

And check out the weather uber-wimps in Seattle - they close schools upon the mere THREAT of snow!! Chained up 80% of the fleet of school buses, then had to take 'em off because they were throwing sparks!

A fair number of drivers in Portland are using Chains or studded tires (which are legal here). ODOT mandated them a few days ago. There were plenty of people adjusting them as well.

Hmmm, you can, but there are two issues to consider:
 
1) There is a very good chance that you will have fender clearance issues both during turning and when hitting bumps. Why? The 215s are fully 1.1" larger in diameter and 0.8" wider than the 195s that are currently on his car.
 
2) If you mount the 215s on the car, you will be traveling roughly 5% faster than your speedometer reads. Said another way, if you happen to roll through a speed-trap in a 65 mph zone on the highway and you "think" you're going 72 (per the speedometer), you'll actually be moving at just over 75. That might be just enough to get you a ticket.

3) For Snow tires you actually want a narrower tire than stock or stock size. The Narrower tires will cut through the snow better than a wider floatier tire.
