Caswell wrote a short time ago stating that Brewsters had altered the wheels on cars coming into their Depot. He now explains as follows:- "Brewsters have not altered the sizes of any R.R. tyres or wheels. English tyres are much smaller than tyres bearing the same dimensions made in America. Tyres over here are heavier altogether. I have just measured two tyres as under:- Prowodnik 935/135 measured 5 1/4" across. Firestone 895/135 " 5 5/8" " They were both the same height exactly. I have seen "Nobby Tyres" 38/8 inches. Mr. C. Kruger of Gothenberg, Sweden, was using this make and said that he found them the best for the rough Swedish roads."
