To be accurate, tires like the Blizzaks or Toyo GSi5 have a proprietary winter tire compound on the first %55 or so of the tread, after that it's a regular winter compound if that makes any sense. I have the toyo on my truck, and the had the blizzaks on my minivan, and definitely noticed less traction by the 3 or 4 winter.
Tires like Xice and Nokian are the same compound throughout the entire tire. I don't know tires like the Xice/Nokian do after their tread is down %50.
To this end, this winter, I got nokians for the minvan to see for myself. I suspect tread depth will probably be a factor regardless of compound type, but just want to test for my own sake.
