| From INDUSTRIAL RUBBER PRODUCTS, Ltd. Continuation Sheet. 1. S.R.Chichester, Esq., Date. 16/2/22. We also enclose a booklet recently published by the Rubber Association of America, Inc. on the subject of straight-sided tires. If the R.R. Company are using another size than either the 33 x 5 or 34 x 5, possibly you will let me know the exact size, but you may take it that, irrespective of the size, the price per mile would work out as low, if not lower, providing the size is not less than 33 x 5. When talking of sizes, I, of course, mean sizes of tires, and not sizes of rims. Thanking you for the interest you are taking in the matter, I remain, Yours sincerely, JOHN COOPER. Enclosures. | ||
