The AEDB record doesn't give a diameter at the bead seat other than the nominal 16".

Grant, thanks for correcting me in that the rim base taper differs between the 6-stud and 8-stud WD split rim. Good to see you quoting the AEDB Design Record, it is those primary sources which we need to refer to more often.

I made that remark as most people think only the rim base taper is different, which isn't true - see Tony's remark below. A 3.5 degree difference in rim base taper would go unnoticed when fitting a tyre. A larger rim diameter does.

Thanks for clearing that up, Tony.
