Yes, the first photos (with fatter tyres) are of the British army (ie the Sudan Defence Force) expedition Model A Fords, under Captain Arkwright in the early 1930s and the last photo (with slightly less-fat tyres) are of Bagnold's Model A's. As fat tyres were adopted for desert use by Arkwright and Bagnold in the early 1930s they were probably the forerunner of the 10.5 X 16 tyres later developed for British army CMP trucks in the desert. I do not know the dimensions of the balloon Model A tyres in the photos, but for what its worth, standard Model A wheel rims from the factory had an outer diameter of 21 inches (1928-29 cars) and 19-inches (1930-31 cars) and Model AA trucks were probably larger.
