Concerning studded snow tires. I also live in Vermont and almost all of my driving experience has been here. 40+ years.
I've found that the tire you choose, like the car, should fit your normal application. If you live well off the main paved roads and have to climb much you might want studs. All wheel drive might let you get by without if your travels take on the higher speed roads for distances a lot.
Studs are best on non paved or covered surfaces. They do slip on warm pavement. Wet or dry. They also are usually on tires that have rubber compounds that will disappear when it warms up.
I run Cooper evolutions with studs on my 2019 SV+. I need to climb a steep paved hill first thing in the morning often before its plowed and then get into the unplowed yard and hill where I work. I am the plow guy. It's a 3 mile commute. I live in town. I might make the trip to Burlington a couple times a month now.
When I worked near Burlington,VT 31 miles one way, I ran the X-Ice on my 2016 SV. I was again the plow guy so I needed to travel early. I needed all the range I could get for that trip. Studded tires take my range down to 2.7 in cold bad weather and 3.4 or so when dry in the 30sF.
For the 2016 I needed the range so I took the hit on better action. I drove accordingly. The heavy Leaf does very well at reasonable speeds in snow if you're calm and plan. If you rally drive on the highway any car with any tire will become a hockey puck if pressed. I have seen many dotting the medians in the 12 years I made that trip.
Studs are loud. Studs don't grip that well on dry or rainy pavement. They don't really belong there.
This was a bit long but I wanted to show the reasoning.
As with choosing which EV to purchase, look at what you do most of the time. Get the tires that suit that need.
I wish the sand paper retreads were still made. They were amazing in the snow and ice. Just don't run them after April. I know the tech has improved and the current stud-less tires are very good.
The GoodYear F32 was another amazing non studded winter tire.
Hope this helps,
