London, S.W.9.

Dear Rothes,

We agree to your changing over to the India Super Tyre.

Unfortunately owing to the absence of wet weather we have not been able to make a comprehensive test on the noise question. We realise, however, that you have to compete with the Dunlop '90' and therefore must widen your tread.

Yours sincerely,
