Excellent subject, Tony, and great pictures!

We have discussed before that these rims have a 0 degree bead seat, so to prevent the tyre from spinning on the rim, a series of notches are stamped into the rim flange to grip the inflated tyre.

Didn't we find out, due to Mike Kelly's measurements of 9.00 X 16 U.S. versus British wheels, it isn't so much a case of the 0° versus 5° degree bead angles, but the considerable difference in bead diameter?
