| x990 COPY. To CJ. from R. {Sir Henry Royce} RL/G15.4.20. My dear CJ., x990✓ X3482 X.3895✓ 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 B (200 T) (S.F. 674 22-5-19) G. {Mr Griffiths - Chief Accountant / Mr Gnapp} 2376. | ||
