got tires changed...hear a bumping sound in back right at low speed turns.

yesterday i took my bmw to get the tires changed...my car has 120,000 miles on it...when i was driving it back home i pulled into my neighborhood at about 20 mph on a sharp right turn...i noticed a bumping sound coming from the back right of my car...i noticed my rims were in different places because of the brake dust that was on the front tires...could it be the rim is bent or what?
