| -2- Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson}5/KW.11.7.35. It is no good our carrying out a lot of tests on the 6¼" tyres if there is no prospect of them having an increased life of 50% over the ones we ran last year. From our experience in France running 6" tyres on 19" rims, it seems doubtful whether we can hope to get such an increase. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
