It was noticed that these tyres held their pressure exceedingly well, which would suggest that the rubber of the inner tubes were exceedingly good, in fact they reminded one of the English made Palmer tyres throughout and the rubber appeared superior to that in general use amongst English and Continental tyre makers. The rim which I had experience with was the Goodyer type of the single split detachable flange, and there was no difficulty about getting this off or on. H & L R.{Sir Henry Royce} EXTRA STRONG | ||
