Smaller wheels and more tire sidewall will give you a more cushy ride. Also less likely to damage wheels on potholes and stuff. And tires are cheaper usually
I ran PS4S on my Model 3 Performance for 3 years and I live in Montana. They were exceptional IMO. Very high performance for an all season tire and don’t have to worry about lower temps. Pretty good in the snow and great in the wet
Edit: meant PSAS4 (all season 4 )
I'm in the same situation. I asked if they could store it in a heated facility over the winter and they said that shouldn't be a problem... My dealer is SLC and I live in Montana
