talking of funny wheels I took this picture of a dual tyre setup on one of the 'D' series Dodges at Kingaroy, Queensland before they were scrapped. Can anyone tell me more about this one?

Tyre size was 7:00 or 7:50 X 20inch

Cliff , the truck may have had 10.50x18 rims to start with and this maybe a modification using 3 ton blitz rims ( 20 inch ) as tyres are easier to come by
