Wheels

I own a set of 4 20" rims. I had them on my 2006 Ford Fusion.

I want to sell these things off and use that money to buy wheels for my Stang.

I am not that familiar with wheels. How do I figure out the exact offset on these rims so I can sell them? I am sure people will want to know what it is before they buy. Unfortunetly - I do not know the make/model of them :(

I went to tirerack.com and figured I could plug in the Fusion and in return recieve rims with the same offset. Currently - after looking around I see rims with a 48mm, 45mm, or 40mm offsets so doesnt look like this will help.

Any info is greatly appreciated.

you could measure it yourself. if im not mistaken and someone correct me if im wrong. the distance from the back of the wheel to the outer edge of the rim is the offset..... (i think)???
 
Correct 05!
Take the wheel off the vehicle, take a straight edge object and lay it across the wheel. Then measure from where the wheel bolts to the rotor and measure to the bottom edge going across the wheel. Keep in mind it must lay fat on the very outside of the wheel lip and not on the tire.
Also, 1" = 25.4 mm
