No, 0" back space the rim would line up with
rear face of the mounting surface, 0" offset
is what you're discribing...

Tough to tell on this one, as I've seen them
Quoted both ways...

A 7" wheel *MIGHT* be an inside measurement, but
it won't be 8" wide, 7.5" maybe, so it'll be a
4" backspace and a 1/2" offset...
It's best to order wheels using the backspace
measurement...

Just to add to the confusion, go here...
