Early CMP manuals call for the tread V down first. This, apparently, gives better traction but doesn't wear as well as you say. For war economy about 1941 they started calling for the open end of the V down first. Wartime photo's would indicate this is what happened but there's lots that show tires mounted in the 'wrong' direction.

Of course the Americans solved this whole problem with NDCC bar treads.

I think it is the other way around.
the manuals, looking at C1, shows the open end down and then i think there was a bulletin saying to reverse that. Maybe debated on MLU some time ago? Then looking at the pictures in the Back Of Bill Greggs vol 1 the pictures of trucks in operation particularly the C60L in the ditch show the point end down or leading.

Harry, go back to the earlier small 1939/40 CMP manuals. By the time of MBC1 the change had occurred to open end of the V down. The ditched C60L (a 13 cab so 1942 or newer) is one of those 'exceptions'.
