Thanks Akkana for the easy method - never thought of using trig. techniques.

Of course, you could always use chalk, liquid-paper, etc. to put a spot on
the tyre tread - no problems if you forget to remove the pins...

This should not be a problem, it's fairly easy to "eye-ball" a horizontal line
across the centre (center for US readers...) of the wheel, and mark your tyre
(tire) appropriately. You could use a spirit level if you wanted to be EXACT,
but the errors of doing it by eye are pretty small.

If you were working on a level surface, and used a spirit level across the
hub centre (center), wouldn't this give you the correct height and position?
