Sure seemed like a lot more difference than that?

10 mm would jam hard against the disc brakes?

I can't measure "offset" (from center?) but I could measure from the back of the wheel to the part that mates against the hub face. The steel rally wheels went with the 'burban but I still have the crappy alloy wheels that were replaced, plus the T400 wheels that I had the centers cut out of.
