They are "standard" rims whatever offset that is.
I had them on my defender they do not pertrude past standard arches, I had it MOT'd with them fitted.
I had my lock stops adjusted for much wider 12.5" tyres so I never noticed any rubbing from these.
Thanks, still interested but pictures tell all - please add them when you have a mo. If you can get the back where the sizing is shown that would be ideal, incl width and ET (offset).
