Technically it is a central European winter tire
Maybe Nokian thinks that. That is why they are POS in winter.
For example tires that you can find in central Europe are: Sava S3, GY UG 9, Conti TS860 etc. which are much better then a lot of "Nordic" tires (whatever that is).
Apparently you're the expert, and I know nothing about winter tires.
So you should already know the weather conditions that is more typical for central Europe, as a resident yourself.
The Nordic region, such as Sweden, Norway and Finland sees a different winter conditions than typical central European conditions (aka not the mountains, like the Alps, and such), where studded tires (Hakka number series) and their non-studded alternatives (Hakka letters, such as RSI, R, & R2) are used.
The central European conditions certain tire manufacturers view the market as more borderline freezing, with more rain and if when it does snow, transitions to slushy quickly, so the emphasis is more on cold-dry and cold-wet than the sustained cold-snow/packed snow/ice in other regions. These are purely friction "Lamella" tires (which that's what the L in the LM-series for Bridgestone Blizzaks signify).
Nitto has a good video explaining things
Now with the All-weather tires, they are targeted to the central Europeans who don't have the luxury of storage space to have 2 sets of wheels to have a 3-season set and a winter set.
Maybe I am expert considering nonsense you are constantly putting here.
What is methodology behind "central European" tire? Sava S3 (which I bet you know what I am talking about), Kleber, Debica, Fulda, etc. Continental TS series, GY Ultra Grip (Euro) series are all, to make it easier for you to understand, real winter tires. I had Sava S3, I had GY ultra Grip 5, 6, 7, 7+, I had Continental TS 810, 830 and 850. I would chose any time for worst conditions those tires then Bridgestone Blizzak WS70 (which I have on Tiguan now) or not to mention Nokian WR that I had on BMW 525d and besides Hankook W300 was the worst tire in snow and ice I ever had.
As for driving conditions in Central Europe, I know, I grew up there, lived there until I was 25. When you have 6ft of snow in two days, temperatures going to -42c, etc. is not something that tire manufacturers are neglecting.
This tire you posted here is considered performance tire here and in Central Europe. Maybe it is hard for you to understand that, but then, you drive on Nokian WR.
