Default Wheel Diameter Help

I'm looking to get the diameter of my C5 polished wheels. I'm measuring from end to end of the actual wheel, is this all it takes to find the diameter?
I know it may be simple to some but I just want to be sure I'm doing this correctly.
Thank you

Well if you have stock wheels they are17" diameter in the front and 18" in the rear. If you have after market I cannot help you, but if you measure from the outer edge straight across the wheel at the center line and that will tell you what it is.
Are you sure you mean the diameter?

A circle has no ends. If you meant ACROSS the widest point of the circle, then you are looking for diameter, and the numbers TR6speed provided are correct.

Rim diameter is measured from the bead seats.

You can always just look on the back of one of the spokes - it will have a number like 17x8.5 where 17 is the diameter.
