I... Well, I had started explaining point by point how wrong this is but frankly the answer is just "all of it, very".

I've driven summer tires, all season tires, winter tires, and studded winter tires in every season in Canada. (Yes, I live in Canada and own borderline-usless summer-only tires. Yes, I've tried driving them in snow.)

None of what you're saying lines up with my own experience, various YouTube videos on braking distances, or literally anything else I've ever seen anywhere.

Edit: And, well, to be clear... I've lived on the West coast of Canada where it's a bit more mild but you're in the mountains, in the middle where it hits -50, and in the East where it only hits -30 but snows like hell.

There are also actual studies that show the difference https://link.springer.com/chapter/10.1007/978-3-031-66968-2_...

Yes, there are. And they show that it's a trade-off well worth investigating. Do you really want 10% better performance on snow at the cost of 10% worse performance on tarmac?

How much do you drive on snow anyway? Probably nowhere near as long as you do on tarmac, even in a tough winter.
