| 1332. Rm {William Robotham - Chief Engineer} /Gry. {Shadwell Grylls} 4/MH. {M. Huckerby} 18th. March 1938. Messrs. Dunlop Rubber Co. Ltd., Fort Dunlop, ERDINGTON, BIRMINGHAM. For the attention of H.E.Price, Esq. Dear Sirs, With regard to the 4 ply tyres which you say will arrive early next week. We should be glad if you would send us figures to show at what pressure the 4 ply tyres will have the same cushioning power as the 6 ply at 28 lbs./sq.in. We shall then be able to compare the relative cornering power both at the same pressure and at the same degree of comfort. Yours faithfully, for ROLLS-ROYCE LTD. | ||
