Wow, that is really amazing.
Many countries here that do not mandate Winter tyres for the whole season still mandate tyres appropriate for driving conditions, which reads a lot like a requirement to use Winter, studded, or chained tyres in snow. Most countries like that also recommend Winter tyres.
It's a very different approach from having many people not use Winter tyres in snow. I think this explains the fear of driving in snow to me. I would be very concerned if I had to drive in snow with Summer tyres as well.
When I looked into getting winter tires, I saw they generally last 60,000 miles or 6 years whatever comes first and since I only drive like 5,000 miles a year, that means I’d have to replace 2 sets of tires every 6 years instead of 1.
If I drove 20,000 miles a year though I’d definitely get them.
You are talking about whether these tyres make sense. In many countries in Europe, this is not a question. It is mandated. I agree with your reasoning from an economic perspective, of course.
