Tires and Wheels problem
1983 Mercedes Benz 300sd Two Wheel Drive Automatic

I would like to jazz up from my stock rims. Is there a list of rims from other cars and car makers that will fit onto my car with out going to the after market and paying big bucks.

I would rather buy from the junk yard and save money but do not know what rims will fit my car from other cars.

Could I use a 15'' rim from another benz or car maker and go with a lower profile tire to stay within the required height. If so what whould that be or where would I find the info.

Please advise. Joe
