Here’s my opinion, for what it’s worth.
I think you should get the smallest rims available (will 18’s fit?) and go with cheap but quality aftermarket wheels.
It’s the same reason most people run steelies on their daily’s for the winter. It doesn’t really matter what it looks like. Winter wheels are going to take a bunch of punishment. They’re gonna deal with the sand and salt and what not on the roads and you’re far more likely to hit a nasty pothole or rub them against a curb or something. The extra sidewall on the tires will protect both the rims and suspension components and using smaller wheels will usually mean the tires will cost less as well.
You might not like the look… but hey… you’ll be that much happier when spring comes and you can get the nice stuff back on.
