The name of the game here is winter grip. It claws across icy, snowy roads with no hesitation or drama.
Our back road was covered with solid ice a week ago, and my car with new Blizzak WS90s barely noticed. My wife's car with 1 season old Nokian Hakkapeliitta was sliding around more noticeably.
When the snow gets deep, and the ice gets slick, these are when the tires really shine.
In the rain, these tires are also really good. They blaze right through deep puddles with no worries.
The previous versions of this tire (WS60 and WS70) had really really sloppy lateral grip on dry roads, so much so that I checked if I had flats, twice.
This version is significantly better in this regard, having minimal lateral sloppiness.
Noise is the worst thing you can say about this tire, and frankly, it's not even that loud.
10/10 if you live in an area where you regularly have to drive through unsalted/unplowed roads, these tires will serve you well during the winter months.
