Wheels

How does one figure out wheel size with offset? It is spelled out on the wheel somewhere? I know they are 18's but where do I find the rest?

On the back of the wheel (usually on a spoke) you should see a marking "et" followed by a number.

So what are the markings on the outside of the wheel directly under the valve stem oriface?
My car has 7 55 (F) and 8.5 50 (R) which I have always assumed was the width and offset size of each rim.

Yes, they are both inside and outside.

Typically the offsets are marked on the back of the wheel, unless of course, you live in a different hemisphere. :p
