Thank you for the tips guys.
The past wheels that were bent were the type pictured in the below link. The front left wheel is the one with the tiniest little bend which wouldn't be noticeable after maybe five or ten miles per hour.
17" wheel on front left still bent
The wheels may be cast aluminum, but I'm not sure. I got them from Vintage Wheels and they look to be identical manufacturing of the original Superformance type, but larger. Vintage Wheels has always given me superior service and even helped me along through the wheel bending ordeal.
