Hi Bob,
I know about the crowd in WA (Who do you think put Tony on to them??) . Unfortunatley they have not stocked 7-50 x 16's for the last 12 months (if ever).
Howard, are you after 6-00 x16's or 7-50? There website is not very helpful at the moment, but they do have the 6-00's on E-bay:

$186 ea. Went up $10 just after Tony Little Jo got his.
Rich.
