snow tire wheels

Aftermarket rims will have oversized hub openings, and you should get adapter rings that fill the gap. As you're thinking: it's not good to rely on the studs alone to keep the wheel centred.

Anytime you order a wheel on TireRack for example, as long as you start the process by identifying your car, they'll suggest the adapter ring needed. Identifying your vehicle also ensures the wheel is within all the parameters, ie: bolt pattern offset, clearance and so on.

Fallen out-of-love with black steel rims?

 

You probably recall when steel rims were silver painted, got chromed acorn lug nuts and a tapped-on hub cap. The latter not a wheel cover: true to it's name, it was a cap for the central hub. Stamped and welded steel rims are relatively low weight, cheap, and looked half-decent. It was the finished product:



Now pretty much every steel rim is painted satin-black, and is not meant to see the light of day: instead they're intended to be hidden behind cosmetic plastic wheel covers that masquerade as alloy rims, and can rival them in cost, lol.

The Corolla steel rim hub opening is a snug fit btw, no adapter ring is needed.
