During WW2, the Australian Government purchased from several tyre manufacturers:
- Dominion Rubber Co. - 9.00-16 and 10.50-20 cross country
- Dunlop Tyre and Rubber Co: 10.50-20 cross country
- Firestone Tyre Co cross country - size not specified
- B F Goodrich Rubber Co
- Goodyear Tyre & Rubber Co, including 9.00-16 RF and 10.50-20 cross country
- Seiberling Rubber Co: 10.50-20 12 ply cross country
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.
