How often do you get the chance to drive on snow or ice that isn’t slush full of grit? An hour/yr?
And do you trust the ability of other drivers, when it comes to them not driving into you, on snow and ice covered roads? I don’t.
Glupton, you’re either trolling or really not looked in to this.
It’s not just about sbow and ice. Summer tyres dramatically reduce their ability to grip (wet or dry) below about 7-8 degrees. It is simply out of their designed temperaure opperating range. So yes winter tyres in winter (colder temperatures) give you significantly more grip whether wet/dry/frosty/snowy. Added to their significant more open tread pattern which disperses water quicker and allows them not to clog up with slush/snow.
I suggest you do some reading comparing stopping distance in circa zero degree tmperatures when using winter tyres against summer tyres.
