| 1331. Rm{William Robotham - Chief Engineer}6/R.{Sir Henry Royce} 10th August, 1939. Dr. J.G. Mackay, The Avon India Rubber Co.,Ltd., Melksham, WILTS: Dear Mackay, Our latest information from France is that the only tyres which will really stand up satisfactory on the 'Corniche are 7.x 16 dimensions. The 6½ x 16 Dunlop Rayon tyres do not last much longer than your light tread 6 x 16 tyres. We have not yet had a tread come off the Dunlop Light Tread 7 x 16 tyres. I think that, under the circumstances, you would like to make a light tread 7 x 16 for us to try out. It seems to me that this might be more practical than trying to bring a 6 x 16 up to the necessary speed resisting standard, and in so doing, reduce its useful wear characteristics to an unreasonable extent. Yours sincerely, | ||
