Nah, single digit offset FTW
True, but you've got 9.5 and 10.5 where as ive got 8.5 and 9.5. Thats an interesting thought if we had the same offset would your wheels stick out an inch more or 1/2 inch more than mine?
It's half the width more i.e. 1/2" more, since offset is distance (in mm) from wheel centreline
