| X4565 HS{Lord Ernest Hives - Chair}6/LG. 28th. Sept. 1923. Messrs. The Dunlop Rubber Co.Ltd., Fort Dunlop, Erdington, Birmingham. Dear Sirs, For the attention of Mr. Macbeth. The Balloon Tyres fitted to the 20 HP. car are still behaving very satisfactorily and Mr. Royce is very pleased with them. We have made some comparative tests with regard to hill climb and speed on the level. We could not appreciate any difference in the performance compared with your standard tyres. We are rather anxious to know when we are likely to have the 40/50 HP. wheels and tyres back again. Also, how you are progressing with another form of tread in order to overcome noise. Yours faithfully, | ||
