| 1331 Rm{William Robotham - Chief Engineer}/PJH2/R.{Sir Henry Royce} 20th September, 1938. The AVON India 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 India or Dunlop tyres. Yours faithfully, For ROLLS-ROYCE LTD. | ||
