2007 S550 mercedes benz front rim
what size RIM is needed for a 2007 S550 mercedes benz for the front
Why wouldn't you just measure one of your other ones, also, your front and rear are the same size unless you use aftermarket and change it. Look at your tire numbers on the sidewall and find out.
If you have no idea where any of that means 18" rims thats what you need.
