A Morris or 8cwt blitz at high speed?

I found another manual "Maintenance and Care of Pneumatic Tires and Rubber Treads" TM31-200 April 1, 1943

Quite thick and has vehicle and aircraft tyres, half-track treads and tank tracks including detailed repair and fitting instructions. Big charts of tire pressures for each size and vehicle type etc.

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.

Good Day,

Here is a reprint from The Australian Monthly Motor Manual 1946 which may be of interest. It was reprinted in the VMVC Newsletter many years ago.

In the article fitting of "Chevron Tread" tyres goes with the open end contacting the ground first for better longevity but admits some loss of traction.
