16'' Knobby or Wheel Swap??

Anyone know of any 16'' rear dual sport/enduro tires I havn't looked at yet? I have looked at Shinko, Kenda and Duro which from what I have found has the only tubeless wide 16'' tire. Any other suggestions? I would like to run a 130/90/16 maybe a 120? Or is there a 17 or 18'' mag that will swap onto the back of my shaft drive 82 KZ 750 Spectre? Seem to be plenty of options for 17 or 18''

Bridgestone Trail wings?

avon am26 is a really good tyre, bridgestone bt 45, pirelli sport demon and duro hf 918.
Al pretty good modern tyres.

Z1000ST (79-80) had a 450-17" rear, don't know if its a straight swap and you may have to use the diff aswell but it might give you somewhere to start,
probably some of the large capacity kwaka cruisers from back then but they're likely to have 16" rears so you'd be back where you started........
