The Wintura + looks a good tyre and after being spanked on cost by the "big 3" brands I gave these a go. First thing that was immediately noticeable was the bouncing, they are not perfectly round and bounce the car, like a wheel balance issue but up and down bounce rather than side to side wheel wobble. Secondly they whine like off road tyres on a 1971 Land Rover and the whine pitch changes depending on steering angle. The reason for buying these was tested on the snow and ice covered lanes here in Yorkshire early 2023 and they were amazing. Excellent grip in snow even when trying to break grip on purpose they felt very secure and match Goodyear and Michelin winters I've had previously and no real white knuckle moments on patches of ice. Wet grip is pretty good and stable but that's about it. To summarize, this winter tyre is excellent in snow and ice, and the rest of the year it "feels" like you're driving on snow and ice.
