You really should. We normally just swap tyres, but this year I bought a separate set of wheels and it's much easier. Otherwise we always have the dilemma of when to change tyres back, knowing that chances are a day after we would have 2ft of snow lmao.
Worst case scenario with separate wheels, you switch them back over at no cost. You keep your summer wheels nice and clean, salt free.
Also mine are 1" smaller and 10mm bigger on the profile, so I have a buffer if I hit a curb in icy conditions.. I got caught out in awful ice a few nights ago and there were a few places where I would of refused to have driven up if my diamond cut wheels were at risk
