Hanno,
I think the obvious answer is that there is no such thing as "the original" tyre manufacturer for CMP's. Both Chevrolet and Ford factory pictures show a varierty of tyre threads and brands. The Good year (Chevron thread, Sure grip) and Firestone ground grip seem plentiful, but you also see the Dunlop Track grip tyres, and also road and sand tyres made by Dunlop, Firestone, Good year and India. Even when looking at rows of finished vehicles at the Ford and Chev plant, you'll note a variety of tyres in a line of the same type of CMP. Alex

I agree that there wasn't a single "original" tire manufacturer for CMPs.
In comparing actual properties (as opposed to nominal sizes) the AEDB record mentions Goodrich, Gutta Percha, Seiberling, Dominion, Dunlop, Goodyear and Firestone as manufacturers. Runflats seem to have been mostly made by Goodyear in the common CMP sizes with a few in "odd" sizes by Firestone and Dunlop". Most sizes of regular pneumatic tires, both cross country and highway tread patterns, had multiple manufacturers. |

As happens today, as well, there were working relationships between auto makers and tire companies.

For reference, An old Dominion Royal 'Trak Master' off my C15. Not so easy to read, so here goes:

So the pattern is likely not original. Owen. DOMINION ROYAL TRAK MASTER 3.jpg

I believe the Dominion tyre shown above is a retread - so the tread pattern to tyre make/model may not be original.

Yes, you can still see the deep cleats of the original pattern on the sidewall.

During WW2, the Australian Government purchased from several tyre manufacturers:
Most orders specified 'casings, flaps, tubes', casings being the tyre. The tyre sizes listed above are most probably not the only sizes supplied by these companies, not are they the only companies from which tyres were purchased - these are just the ones I have ordering data on.

I've not seen that marking myself. Interesting it is 1 and 1/2 degrees. When looking at the British divided rims, the two halves have a pretty flat or level appearance, but apparently there is a 1 and 1/2 degree slope there.
The American system has tires that have the steeper bead angle , I believe this follows on from the normal commercial tire designs of that period. Some people have reported as having no trouble with fitting the newer recently made ( Chinese ) tyres onto the British or CMP rims so it may be the case that some of the individual brands are allowing for the different tolerances. I spotted a CMP at Corowa with the Chinese tyres on it and spoke to the guy at length about tyres , he made no mention of having trouble with the fitting. He drove the truck across the Nullabor all the way from Geraldton. Apparently the CMP C8A six stud rims will accept anything - US or British.
