Front-right wheel making sound when I back out in reverse (turning the steering wheel to the left) but not the other way.

Kind of hard to describe the sound... kind of a grinding/rubbing sound. I also hear a slight rattling sound coming from that wheel (I think) while driving, especially over bumps.

I bought the car used and it already had aftermarket rims, maybe something with that?

It's a 2007 Dodge Charger R/T.
