Hey folks, I’ve been hunting for used wheels to have a spare winter set for my astro van. I found a set of 9C1 chevy impala rims for cheap, the bolt pattern is the same, the center bore is the same, diameter and width check out, but online it looks like the Impala has M12 studs while my van has 1/2” studs. I know M12 is a tad smaller in diameter, but I’m wondering if it’s close enough to be within tolerance.

For reference this is a 97 astro and wheels are listed as fitting a “94-96 Impala SS”
