| X.3895 COPY. Answered 19.4.20 To C.J. from R.{Sir Henry Royce} R1/G15.4.20. My dear C.J., x 990 x 3482 Re Dunlop Tyres on Michelin Disc wheels. CJ10/D9.3.20. This supports my contention that high speed and power cars should have tyres fitted with security bolts. I am using American straight sided tyres and think they are very good indeed, as far as I have seen them. Nothing else I think should be used on American cars, where such tyres are available. Our makers seem behind, unless I am mistaken. Yours ever, sgd. R.{Sir Henry Royce} R.R. 235 (T) 200 (S) F 674. 22-9-19. O.{Mr Oldham} 2376. | ||
