I think at least some of the British rims were made by SANKEY .... Was Sankey owned by Dunlop ? Pretty sure my Morris CS8 rims are marked SANKEY but I will have a look. Also found brass wheel nuts on a CS8 I have ....

BTW that's a nice original Maple Leaf truck . Are those 10.50 x 18 tyres

Yes, 10.50-18 tyres on 18x8.00 rims.

A bit of parallax in the photo but when I got down to the level to the wheel the measurement to the bottom of the angle iron from the mounting flange is 4-1/4"

Hope this helps.

Hello Jacques,

Thank you very much for the clear answer and photos, it is a great starting point… As for the rest of the thread, I was hoping it would stay close to the specifics of my question, since after reading all the additional wealth of information, while useful in many ways (it can become difficult to retain very fast) since we start to deal with other details that are not pertinent at the moment...

Please forgive the seemingly ungrateful reply, but it is not my intent... I appreciate all the additional very technical details, but I was only hoping we would remain within the confines of wheels that use the GM 10 X 7.25 bolt circle with a 4.75" pilot hole and designed with either 8 or 12 studs holding the two halves together. I realize that turns into 2 different wheels and more apparently!

For the sake of simplicity, shall we first classify the wheels that only share the 10 x 7.25 bolt circle with a 4.75 pilot hole? Perhaps that should have been the title of my thread. My apology for it is a huge learning curve here...

To the point, and as indicated by Tony Smith, on the 10 x 7.25 bolt circle wheels manufactured by GM/Holden Australia we have:

1- 16" x 6" (8 bolt split wheel)

2- 18" x 8" (12 bolt split wheel)

The next style would be a 5 x 7.25 bolt circle and 4.75 pilot hole also, unique only to Australian Maple Leaf Trucks, also made by Holden…

A) 18" x 8" (12 bolt split wheel)

Furthermore, I understand that there was also a 20”x 8” (12 bolt split wheel) that shared the same bolt circle with and pilot hole; manufactured also by General Motors in Holden Australia… Is that correct?

Lastly, would it be accurate to say that all these 16”, 18” and 20” split wheels share a backspace equivalent to the 16” x 6.0” (8 bolt) Ford Kelsey wheel which was 4 -1/4”? or...
Does anyone have the definitive answer?? Which would bring us to the next maze of information- that would pertain to all the different axle combinations (with or without wheel spacers) used under these 1.5 ton 133” wheel base vehicles with a combination of either one of these wheels…

My response to you (without the benefit of photos, as I can't view them on Facebook) was regarding the 16" 8 bolt (8x lug bolt, 8x dividing rim bolt, I would describe that as "8 Bolt") rim, which I said was the standard WD/DND rim made by Kelsey, GM, And Dunlop. It appears they were also made by Sankey. This is not a 10 x 7.25 bolt circle wheel. As far as I know, this rim was never manufactured by GM/H in Australia. This is the same rim as pictured by Andrew H and Jacques.

On 1533 trucks (and 15cwt CMP's) this was fitted with a 9.00-16 tyre, while on CC60L trucks (and 30cwt CMP's) it was fitted with 10.50-16 tyres. These are Canadian vehicle designs and production features.

[Tony Smith]

The GM Canada 1543X2 had 18" wheels with a 10 x 7.25 bolt circle and featured 8 dividing rim bolts. Again, this is a Canadian design and production vehicle. The X2 indicates the vehicles were assembled in the UK. Some of these vehicles came complete to Australia, but they also saw service with other countries, such as Poland.

[Tony Smith]

ONLY the GM/H assembled vehicles has the 18" wheels with a 10 x 7.25 bolt circle and 12 dividing rim bolts. I have not seen a chassis code for these vehicles, but they are not completely manufactured by GM/H. The chassis and major components were sourced from GM Canada, with local items like the cabs and wheels made here. As their payload rating is the same as the 1543X2, but assembled here, the code may well be something like 1543X4 (X4 for Australian assembly).

Hi Tony

I see we are reading from the same Chevrolet army parts book.........

This has me puzzled....... the parts list only references * indicating 32x6 tires or X indicating 10:50 x 16 tires........ from what you are saying it seems to indicate they were fitted with 18 x 10:50 tires/rims when re-asssembled in the UK for Poland or Australia.

So complicated.

I've learnt quite a lot here - thanks all - so my C15A wheels are interchangeable with my CS8.
I am also about to procure one of half a dozen Lend Lease and Mapleleaf trucks - I have a better idea of what am looking at wheel-wise now!

[Bob Carriere]

Dave

Is a CS8 the basic frame of the HUP....... in which case it has the 16 in. rims but only 6 bolts to the brake drum....... while the C15A uses the 8 bolt pattern.

Looking forward to seeing photos of your new acquisition....... front back sides underneath for frame stiffener and some focus on the tires, rims and bearing cap in the centre of the rim...

Cheers

[DaveBuckle]

Maybe too many abbreviations: Surprised to learn that my Chevy Blitz (C15A) has the same wheels as my Morris CS8. Went and had a look and took a pic to double check.
And yes, will post a pic once I have procured one of those trucks - maybe a while now with the way things are progressing, but then again, has been nearly a year in waiting - I'm sure we all know how that goes with these rusty relics ...
PS - I thought it was great that the Morris tyres "still held air" - seems they are full of concrete (or similar) can't even lift the spare to vertical off the ground ...

Philippe, can I side track you to find out some details on the tyres on the front of your truck. I have a 900 x 16 tyre that was made in South Africa (on the tyre it says" made in the Republic of Suid Afrika") I assume yours are 900 x 16? Are they currently available? Are the dot rated? I need to pull it out for another look. It came on a 3/4 ton WC Dodge. (Can I mention a Dodge in this thread?)

Dave the CS8 originally had Run Flat tyres ( heavy ) ..no spare wheel was issued. I've cut open four of those RF tyres with a chain saw and then a angle grinder to cut the bead cable, horrible job . An old guy at Whittlesea Nth of Melbourne told me his dad purchased a CS8 around mid 1945.. the CS8 was knocked back for rego because it had no spare wheel , the owner went back to the Morris dealer and a spare CS8 was wrecked just for the wheels to go with the others for sale. The old boy Marshall said they had two trips to Sydney in the CS8 towing a horse float ! 40 mph all the way . The CS8 was traded in around 1952 for a new Land Rover . I was offered the rear axle housing from the spare donor truck. Funny thing is another Whittlesea CS8 surfaced years later , a guy at Bendigo swap had a CS8 radiator surround and a set of wheels for sale , he told me his elderly neighbour had a CS8 converted into a camper back in the 1950s , it had been sitting unused for many years. As the CS8 was towed out of the neighbours yard, the chassis broke in half ... rusted through. He salvaged the cast brass body ID plate which i have.

Your tire may not be filed with concrete the rim/tire combination weights in around 160 pounds.....maybe more with run flat.....

Mounting the spare tire into the HUP side wall bracket is a two healthy men job.......

If concrete filled you will have a bitch of time removing the tire casing unless you use a grinder wheel into the side wall and expect lots of blue rubber smoke Phew!!!!!!

Stay healthy.

The there are the 18" six-stud Inter wheels. Just to add to the mix...

Cheers,

And maybe these super rare 5 bolt 18" on a Ford but I don't want to get off topic..

[Bob Carriere]

found the pictures of a British made rim that floated to Canada???

[Philippe Jeanneau]

Beauty, but from the photos it sure looks thinner than 5/16" Amazing how deceiving it can be... The new solid blanks are 0.187 or 3/16" considerably thinner but with a 3/8" flange...
