| To Roy.{Sir Henry Royce} from Hs.{Lord Ernest Hives - Chair} C. to By.{R.W. Bailey - Chief Engineer} X4820 Hs.{Lord Ernest Hives - Chair}2/MJ.17.7.29. X4050. X7820. TYRES. ----- Rn.{Mr Robinson} is at present in France making comparative tests with various sized tyres. We have had a preliminary report, which indicates that we shall not wish to alter from the present 675." dia. We think you should communicate this with Dunlops and suggest that they fix up an appointment to come over here, because if they are to stop making the sizes we require then we have no alternative but to go elsewhere.
