Default Tread patterns again

I have been reading "Design Record Canadian-Developed Military Vehicles World War II". This is a summary of the experiences and design decisions made during the CMP program. It is in 8 volumes and in volume 4 tyre production, size choices and wear considerations are discussed.
Firstly the loss of the major rubber producing areas is discussed. This was a serious enough situation for a number of hitherto rubber parts (including the windscreen blocks on the Jeep and motor bike twist grips) to be made of alternative materials. It may be that the transition from rubber boots round the levers in the CMP cab changed from rubber to canvass at this time for the same reason. Then the topic of which way round to mount the tyres is introduced. Though specific instructions were issued one is left with the feeling that they were not strictly adhered to.
