4th October 1928.

Messrs. Rolls-Royce Ltd.,
DERBY.

Attention of Mr. Robotham.

Dear Sirs,

Mr. Paull has received your favour of the 28th ult. (reference Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}4/LG.) informing us that you are anxious to obtain some Silent tread tyres for the 20 h.p. car to go on to 19" rims. This is followed by your letter of the 3rd inst. informing us that Mr. Royce is anxious to have these tyres for his car.

We take it that the 6.00 section tyre is what you have in mind and for the 19" rim the tyre will be called 31x6.00.

Tyres of this size can be provided as part of our current manufacturing programme, but these are not in the Silent type.

If it is only the effect of size which you wish to determine, then there will be no difficulty in sending you the current Buttressed Triple Stud type, but if you must have Silent for experimental purposes, then it would be necessary for us to make moulds specially and this would probably involve a delay of some weeks.

We had in mind only producing Silent tyres in the sizes which would be used by cars of the luxury type where silence is of relatively greater importance. The 19" rim has not yet come before us in this connection, but we have in mind making Silent tyres for experimental purposes in all the likely rim diameters for the larger sections of tyre, and as there may be some likelihood of your adopting the 19", we are proceeding to deal with that size.
