Here's that report I promised on how the Nokian WR G2 SUVs handled on BC mountain passes in winter. I had a set of Thule chains with me, but never even considered putting them on because the Nokians did so well.
1. Coquihalla Pass -- Starting up toward the summit, all the semis were pulled over chaining up, so the three of us in the Trail Edition had the road to ourselves. The temperature was just above freezing, and the road conditions were slush over ice -- really ugly -- but 4H and the Nokians handled the situation easily, tracking straight up to the summit where the road condition changed to snow. Coming down the other side on the snow I switched to 2H, and the steering and traction were very stable.
2. Paulson Pass -- heavy snow, no plows anywhere, and bad visibility in the dark, but no problems in 4H. Saw a guy in an Infiniti sedan up ahead of us break loose and do a couple of loops, but he stayed on the road and didn't hit anyone. Not sure what tires he had, but suspect they were "all-season" (one of the most misleading marketing terms ever).
3. Allison Pass -- deep slush, with all the other cars and pickups slowed to a crawl with their drivers squeezing the wheel. Again, the Nokians gave excellent traction and stable steering in really greasy conditions. We finally followed a semi at about the speed limit down from the summit to where conditions changed to rain.
Summary: The Nokian WR G2 SUV is not designed to be an off-road tire, nor do I plan to run them in summer, but if winter includes snow, slush, and ice in your region, this tire is worth considering for your 4Runner or other SUV. It also resists hydroplaning well, should your winter include a lot of rain like ours does.
Anyone else using these tires care to comment?
