<s>Lay a straight edge across theback side of the tire</s><s>and measure from the straight edge to the mounting surface, then</s> measure from the straight edge to the outermost part of the innerwheel lip. <s>Subtract the 2nd number from the first</s> and you havebackspace. Now you need to wheel width to figure out offset which is therelation of the mounting surface to the centerline of the wheel (from lip tolip).

I used to have a performance shop and this was the quickest method I found to find out what a customer had on the vehicle to start with and then go from there. I always found BS to be easier to work with and explain to the customer than offset was. Lower BS, wheel moves out. Higher BS, wheel moves in.
