| 1331 Rm {William Robotham - Chief Engineer} /PJH2/R. 20th September, 1938. The AVON IndiaProduction 20 HP. with 4-speed box and Front Wheel Brakes Rubber Co., Melksham, WILTS: (For the attention of Dr. J.G. Mackay) Dear Sirs, We have now completed our Skid Pan tests on your 6.50 x 16 bisected narrow groove tyre and enclose a curve showing the results. We have also tested Dunlop Fort and "90" tyres and these results are also shown. As you will see the bisection of your tyre has improved it slightly, but it still has considerably more slip angle than the IndiaProduction 20 HP. with 4-speed box and Front Wheel Brakes or Dunlop tyres. Yours faithfully, For ROLLS-ROYCE LTD. | ||
