[DeTomaso] Wheel offset (ET)

[Bjoern Flesland]

So I need to use TOTAL overall rim width to calculate ET? Correct?
I do not want to measure the ET.
I want to calculate it, so it equals with the stamped numbers. 
And so I know for sure what I am dealing with.
Cheers Bjoern

You can assume that the outside of the edge is 1/2" further out on each side of the rim but especially on aluminum rims this measurement can differ from side to side on the rim. My calculations were assuming that your reference was the same for BS and rim width. If they weren't my calculations are off.
