Update - I ended up going with separate winter wheels (OEM Volvo 19" Polestar rims) and 'performance winter' tires (Michel Pilot Alpin PA4) to improve traction in winter and avoid sacrificing handling in summer (by keeping summer tires and not A/S tires).
It's that time of year.
I need to decide which tires to get for winter here in New Jersey given we get snow and ice and summer tires can't be used in snow and ice:
1) Separate rim and tire set for winter.
19 inch rims with winter performance tires (Michelin Alpin PA4/PA5) depending which is available in Polestar's 19" OEM tire size.
2) Use one rim and 'All Season' tire set all year long (20 inch).
I.e. Remove stock tires (great summer tires Michelin Pilot Sport 4S) and switch to All Season tires, either Continental DWS06 or Michelin Pilot A/S 3 Plus.
3) Use one rim and 'All Season' tire set all year long (19 inch).
I.e. Buy 19" rims and fit them with 'All Season' tires, either Continental DWS06 or Michelin Pilot A/S 3 Plus.
A possible fourth option (probably not necessary given we do not get a ton of snow) might be one set of rims with 'all weather' tires such as Nokian WRG4 (not to be confused with all season tires) if they have them in the right size.
These would be better in snow than all season tires but (probably) even less capable than all seasons, from a handling perspective, in non-winter. Think this option would be lowest in terms of preference and probably should be ruled out for my needs.
Open to suggestion/ feedback regarding which option you would choose!
The disadvantage to options 2 and 3 is obviously sacrificing some (how much???) handling performance (cornering especially) in non-winter weather.
The benefit to 2 and 3 is not having to 'swap' wheel + tire sets twice a year. I say "swap" since "mount" is not the right word, since the tires will already be mounted to the rims.
