So how about that, front wheel flew off!

So don't use a wire wheel but a brush? I'm gonna buy new wheel studs for the wheel that came off, but just to be safe I'm gonna clean up all the rest

Also it isn't a crack in the wheel that was just like some road debris or something, it just has that chip. Is it still good? Like can I still use that wheel?

Wheel should be OK. I'd round off any sharp edges.

You'll want to re-torque those new studs and nuts several times to make sure they seat.
