http://www.oldcmp.net/wheels_tyres.html goes to an old Canadian vehicles site and there there is a picture of a tyre with the same markings except that the year is 1942. Text attached states that "Worn 1942 dated Goodyear NCD tyre for 16" rim. This is a Canadian tyre. A good example of a 16" Dunlop Track Grip Chevron pattern directional tyre" (if I'm teaching grandmothers to suck eggs my apologies). There is also a photo of such a tyre still attached to a CMP in Australia where I understand many such vehicles went to die at the end of WW2.
