| 1332 c. Roy. {Mr H. Royce - Buyer} Rm {William Robotham - Chief Engineer} /Gry. {Shadwell Grylls} 7/MH. {M. Huckerby} 6th. October 1938. Messrs. Dunlop Rubber Co. Ltd., Fort Dunlop, Erdington, BIRMINGHAM. For the attention of Mr.H.E.Price. Dear Sirs, For some reason we have not yet fathomed the 7 x 17 "noisy" tyres we have been testing on Wraith have to be let down to about 20 lbs. pressure when hot to give as good a ride as the standard arrangement. When the "C" type mould is ready will you please, in addition to the 5 tyres already requested, run off 4 more with 4 ply cases and send us these for test. Please have them marked very visibly "4 ply". Yours faithfully, for ROLLS-ROYCE LTD. | ||
