| A 121 D.{John DeLooze - Company Secretary} R.{Sir Henry Royce} CO., LTD. SHEET NO. 2. 23rd Mar: 19 '29. Messrs. Rolls-Royce Ltd. We are also quite unable to understand why the tyres should be extraordinarily difficult to mount and remove. If Rolls-Royce of America care to tell us which well base rim they are using and the sizes of tyres fitted, we will be glad to see whether we can throw any light on the subject, if this would interest you. It will be sufficient if they will quote the designation of the rim, American drop center rims being described as follows :- 2.75"-D.{John DeLooze - Company Secretary} (Ford). 2.75"-D (Standard) 3.25"-E (Standard) 3.62"-F (Standard) 4.00"-F (Standard) Yours faithfully, for THE DUNLOP RUBBER CO.LTD., W Bond Development Manager. | ||
