This is a major problem for the 17" Moulton.
'Major' problem? Meh. If you want to go on a world tour on your Moulton AM, rebuild the wheels with 18" rims and use Schwalbe Marathons in ISO40-355. Or perhaps you could rebuild with ISO349 rims; some Alex Moulton owners have.
I haven't looked into this: possibilities of using other perhaps more common/more available rim/tire sizes on the Helix?
