After going at this for a while, I am trying to make this a reality by coming up with a wheel similar to the original made by GM of Canada in the 40's... Seeing that we're stuck with 20" very rusty and sometimes dangerous wheels with very expensive replacement tires, I figured I try another option for our 1.5 ton and smaller trucks, with a new 10 x 7.25 bolt circle 16" split wheel... The benefit of the two piece is handling, requiring no special equipment to change a flat or swap tires...
So far I have the following information regarding the original Canadian 16" wheel:
Rim Size: 16" Width: 7-1/8" approximately... Backspace: 4-7/8
Bolt Pattern: 10 x 7.25" Flange thickness: 19/64" chamfered for wheel nuts.
The new wheel (minus the stem valve protector) would have different backspaces front and rear and be slightly wider (about 8.5" overall) to fit the U.S. spec. 1.5 trucks... If anyone out there is interested, please chime in. This could be a nice solution to a very old problem...
