Sorry, but with problems getting on to the forum and generally slow internet over the last few days I haven't been able to find the pictures at the moment. Or it may be in the Brooklands book. There was a major tyre and fuel shortage in the US. As part of the fuel rationing requirments car and truck owners had to have a monthly certificate of inspection on tyres before fuel was issued. The result was that vehicles not being shipped for immidiate service were placed on economy tyres and no spare. There is a photo of a Dodge 3/4 ton on these tyres, similar to the small tyres fitted to the 1/2 tonners, and just a rim on the spare bracket. Did find this though http://www.ameshistoricalsociety.org/exhibits/events/ww2ration.jpgA British veteran told me than when an American convoy went by, a soldier was sent out on a bike to follow. His mission was, should a truck breack down and be left to phone the camp. At which point they dispatched a truck to strip anything useful, including tyres, before the recovery came back. :-D The Yanks cottoned on very fast and started leaving armed escorts with the vehicles. It wasn't only an allied problem, every sort of tyre, down to biycycle tyres were taken by the Germans from the Channel Islands.
