Not any more dangerous in wet than a traditional/hardcore non-studded winter tire.Been looking for this data forever, awesome someone finally tested it. I've left my summers on so far this winter as it's barely gotten down to freezing, but wow they sure are dangerous in the wet.
The guy in the video made a mention of how you can't judge solely based on those numbers, and there's an element of feel to take into account. If you live somewhere where it's very wet, slushy, icy during winter, the true winter tires do hold an advantage in feel and response, while the *good* all seasons come close, but won't feel as stable. As soon as you're driving on snow/ice though, the winter tires are always far more stable feeling, so that WHEN you start to slide through a corner, it's progressive and easy to control (fun) vs panicking and fighting to regain control.Close to an ultimate tire review. These guys are doing a great job and thanks OP for posting this!
I'm surprised to see the little gap a hardcore winter tire makes on the packaged snow over the other winter (performance?) tire and the two all seasons. Could this be due packaged and possibly artificial snow?
And for all those hardcore street racers out there with their upgraded summer rubber trashing A/S tire as a no season tire ... okay! LOL
The real question is, how would Blizzak WS80, Michelin Xi3, Continental WinterContact Si for example compare to these Hakka R3's in the wet and dry braking? I'd assume these studless winter tires in US would fall within the "nordic" category whereas the "winter" category from this video would represent a performance winter tire. C&D tested studless winter competition (Hakka R2, Xice3, Si, WS80) back in '15 .. https://www.caranddriver.com/features/a15102773/best-snow-tires-for-winter/
So unless you're running performance oriented winter tires or the awesome all-seasons (like OEM p7s ), you can find yourself in far worse position in wet and/or dry on a hardcore studless/nordic winter tire vs summer rubber.
