Today we made and installed new sills for the running boards from 2mm sheet steel, made new floor boards from 20mm plywood (the original steel floor was toast) and bought four used radial tyres. The modern tyre specification equivalent to the original 10.5 x 16 inch tyres used by the LRDG is 265/75/R16 but strangely that outer diameter is too small compared to the tyres shown in the WWII photos. The second-hand tyres we bought are significantly larger at 315/75/R16 but much better-proportioned (see pic).They are worn but have enough tread for our purposes. We gave up looking for correct 10.5 x 16 sand-pattern tyres with highway speed capability, a long time ago. But we will have to remove that Yokohama brand name!
