No, none of them did, but they do share the same wheel stud pattern, as evidenced by the number of Farm Blitzes in Australia that have fitted Civillian Bedford Duals to 60Cwts to increase their load capacity for farm use.

It is curious that this same 10 1/2" bolt pattern from WW2 has endured to the 50's and 60's, where it has received the term "Bedford (DIN)" of 8 on 275mm.

Default wheels

I recall borrowing some Bedford O model truck wheels from a guy in Orange, I fitted these wheels on a WOT2H I was given for free, near Canowindra NSW . My nephew steered the WOT2 as I towed it with the Dodge ute to Cargo. That WOT2 ended up in a collection in Sydney , the Ford was seen in a W&T article featuring that particular collector's trucks.

To complicate things further, DIN is the German standards authority, like SAE in America and BSI in the UK. I can't see why Bedford would ever have done anything to a DIN standard.

Quite right David. I did a search and it seems that an Australian company that makes agricultural trailers and axles lists hubs with 8 studs and 275mm PCD as 'Bedford DIN', as well as European truck wheel specs. My guess is a lot of truck wheels are reused on trailers and hubs are made to match them. Just someones interpretation I guess.

I also measured a wheel and PCD is as quoted in the Vocab .. 275mm

I’ve got some WD wheels to resurrect that have some broken studs. Does anyone have any for sale?

Default Wheels

Just to prove I'm not making things up, here I am just arriving with the WOT in tow after a 30Km + drive from the other side of Canowindra. The WOT was stuck on a log in the corner of a lucern field, took me a while to free it, it had a farm/property name on the door , Canberra of all places. The Dodge I paid $400 for in 1978 with original 1946 rego .

Triggered by Jacques’ photo and on closer scrutiny of this Canadian made rim, it does have a vaguely visible maker's stamp "General Motors Canada 1941".

Worth a read if you want to turn down your rims to fit new tyres currently available.

The 16” divided rim has plenty of thickness to allow machining 0.125” off:

In the article Jim describes his modification as not attempting to machine the 5 degree taper used on the Dodge rim but instead to machine the new seating area parallel and about the same diameter as the mid point of the bead contact area of the Dodge rim. I would have thought that any lathe capable of this machining could have just as easily reproduced the 5 degree taper and exact start and outside diameters of the American standard. This would provide a better seat for the bead and make dismounting easier if needed. It really is not hard to change the angle of the compound slide and turn the handwheel manually on any lathe !

One thing that would concern me about turning a taper would be to minimize the loss to the rim near the join line. In other words: if turning a taper, just put it in the area nearest the flange, then turn a parallel section further inward to maintain thickness/strength.

Default Cornphusing......

I find the last post confusing.....

Seems we all measure differently...... and do not identify what the wheel came from (type of vehicle).....

It is my opinion, based on some reading originating from a GM publication.....all older original rims were made by GM and stamped.....later the rim manufacturing was transferred to Kelsey Hays and they used a similar stamp with the Kelsey name instead of GM.......Kelsey became an outside supplier some time around 42 to 43...... and there may have been some overlap.... the rim press is photographed in some old GM publication....about 3 stories high and sunk into the floor to the basement for clearance of the flywheel......operators are feeding precut circular 1/4 in. steel plate and it seems that they where punched/shaped in one go with the center opening.....the stud bolt holes were probably done in a separate indexed gang drill operation as they were also tapered for centering purposes....... the CMP wheel can be said to be center and bolt centering as the seat of the nuts are tapered and the center opening rest on the raisea groove on the brake drum.........civilian GM wheel of the time where self centering on the axle stub only using flat shouldered nuts...

From experience 900x16 and 900X10:50 Tires will fit US and Canadian CMP rims without modification IF you use special tire lubricant on both the tire and the rim face. On HUP vehicle with original rims mounted with 9.25x16 tires the vertical section of the HUP rim seems to be more parallel as opposed to a slight taper on the regular CMP rims. It makes mounting and removing ( the tube was pinched) by far easier.

Default Backspace and offset on a 16" Kelsey CMP wheel

here is the link below.

I was replying to a 2019 query by Philippe Junneau about "backspace" on 16" Chevrolet wheels.
Photo in question is a 1943 Kelsey 16" wheel from a Ford CMP.

Recently on Facebook a question was asked about wheel offset on CMP trucks and I used the same photo and dimensions to obtain the offset.

As we all measure things differently, here is how I measured the PCD of the wheel mounting studs:
Put the ruler exactly on 10" on the edge of the hole on the centre line to get a sharp starting point. corresponding position on opposite hole is at 20-13/16" -10" = 10-13/16" Even allowing for minor discrepancies it is neither 10-3/4" nor 10-7/8" Holes are not flogged out of round either to affect the measurement.

Hope this clears the confusion.
