Rm {William Robotham - Chief Engineer} /FJH. {Fred J. Hardy - Chief Dev. Engineer} 2/AP.

Messrs. The Avon IndiaProduction 20 HP. with 4-speed box and Front Wheel Brakes Rubber Co.Ltd.,
41 & 42 Livery Street,
BIRMINGHAM 3.

For the attention of S.Lovell Hewitt Esq.

Dear Sirs,

We enclose two copies of the results of our tests on the various tyres you sent to us. The table shews the actual figures obtained and the graph shews the averages plotted against sideways acceleration.

We do not know whether the curves should cross as some of them do but if this is due to testing errors the discrepancies do not appear to be serious. The 6.50 X 16 IndiaProduction 20 HP. with 4-speed box and Front Wheel Brakes tyre is of 6 ply construction.

We hope you will find the results useful.

Yours faithfully,

FOR ROLLS-ROYCE LIMITED.
