If you buy a new set of wheels, the pressure sensors for the valve stems also cost extra, and I think have to be paired with the car using a scan tool, depending on the manufacturer. So if you’ve got separate winter and summer tires, the sensors have to get updated each time you change. (Maybe some manufacturers have figured out how to auto-pair based on proximity? but idk

Of course! You change the entire (en-tyre?) wheel, not just the tyre. I kind of assumed it was a twice a year thing that you would do at a tyre shop.
I imagine its a pain but it must feel good going from slippery summer ones to something that sticks - to ice!?

Many people do just have one set of rims and have a tire shop swap them out. In that case they wouldn’t have to charge the sensors, but you need to pay someone with a tire machine every time then. I have 2 full sets of wheels so that means I can change them out myself at home, which is particularly useful if there’s ever a surprise early snowstorm or I’ve been procrastinating swapping them.
Having proper snow tires with their soft rubber and special tread pattern definitely makes a huge difference in cold-weather traction. Even if the road is dry but below freezing, a winter tire will handle a bit better because a summer tire’s rubber is designed for higher temperatures and will go stiff in the cold. The tread pattern is designed to have snow pack in and stick to it, since snow sliding on snow is actually higher friction than rubber on snow. With the right tires you’ll bottom out your car in the snow before you get stuck from loss of traction. Pure ice is a bit of a different story. The only real solution for that is tires with metal studs in them, but they’re illegal to use on the public roads in the city because they tear up the asphalt.

Its just a different world for me. I was watching some of the rally footage of studs & wondered what happens when you go too fast with chains on. Obviously disaster but youtubes all knowing algorithm wants to protect my eyes.
