I'm not sure, I might have a set of 15" rims around the property somewhere and I'm pretty sure it's the right bolt pattern but I'm not 100% sure.
It'd be annoying to have my winter tires be the wider, slightly narrower sidewall wheels though, and then use big, fat, narrow tires in the summer which I think is the opposite of what you want in both situations for optimal performance. I'll keep watching for deals on new wheels/tires though, of course there's plenty of time to wait for a good deal new or used before summer.
Edit to add: does anyone know if a 17x7 wheel with a +38 offset would fit? I know looking at wheels on tire rack and discount tire and all those places they're usually like 45-50 offset. But these wheels are super cheap, not super clean but cheap and functional is more than enough for me.
