It is.

However the difference between winter and a modern all weather (it's a different class) isn't.

And yes, we're probably terrible drivers.

I do not live in Florida. 45N, continental winters.

I'm never using winter tyres again unless society breaks down and no one shovels the roads anymore.

There are laws of physics you can’t hand waive away. Winter tires are really more cold temp tires. The rubber formulation is different to allow for grip in the cold and dry (tread pattern for cold and snow). As such a winter tire wears heavily driven in the summer, rubber formulation is just too soft.

For an all season that level of summer wear would be unacceptable. So a different formulation is used to improve summer wear at the cost of the winter low temp performance. You can’t have it both ways, a long wearing summer performance and good sub 40 degree grip.

Please read the studies in this thread.

Modern high quality all weather tyres are excellent in summer and winter.

Except on actual snow, where they're just ok, because of the hybrid sipe patterns, and ice, where they suck exactly as much as everything else except studded tyres (which suck on tarmac instead).

They are still worse than winter tires in cold dry conditions because the rubber compound is compromised to have acceptable summer wear.

Even after the streets are plowed there's still a bit of snow on the main roads and a lot on the side roads. Maybe you live in a place with really mild winters, but my car would have drifted into a ditch many times this winter if I didn't swap my tires.

No one is saying to drive all year with your summers. Those will glass in winter.

Assuming every road you drive on in the winter will be perfectly plowed and salted is a great way to end up in a ditch.

It's a 10% grip difference, which is actually in your favour on cleaned roads and only against you on snow.

I really don't understand how this is so difficult to grasp.
