The ice grip stuff is what matters to me. Looking at acceleration, on a flat surface, the studless aren't even close.
In my experience, this studded v. studless ice forward traction difference gets greatly accentuated as grade increases, with studless side slipping with VDC off, just putting on the brakes with VDC on, and unable to generate forward traction on a heavier long wheelbase 2WD.
Sounds like Nokian has taken advantage of being able to employ more studs, and that's what would be key. I get anybody with a performance sedan wanting to keep more dry pavement performance, but this is a minivan. Studding it had no negatives at all. I doubt they have the size I need, though .
Edit: so they don't have my size 225/60/17...
...but then I see the Hakka 8 SUV, and they do. That tire looks to be more aggressive than the car version, which is what I want anyway. So...I think we have a winner.
Now I can test the best winter tire, studded, on the worst possible drivetrain with crappy weight distribution, against a winter rated all terrain, rolling 37", on the best possible drivetrain, perfect weight distribution. My annual apples and avocados test .
