I have been using those tires in a wide range of situations: from German autobahn at 180kph+ to deep snow passing trough hot weather and mountain roads.
Overall, when the wether is dry, hot, snowy and icy, the tires are performing fine (especially when new). The only real concern is the total loss of grip I am regularly facing when driving under rain. I noticed this to be likely related to the wear of the tires too.
My conclusion: it is an ok tyre when use for what is has been intended for (Nordic winter only). However, there are tires with better performances on wet. Therefore, I would definitely not buy them again, especially when considering the asking price…
