| to Roy.{Sir Henry Royce} from Hs.{Lord Ernest Hives - Chair} X1050 Hs{Lord Ernest Hives - Chair}5/LG16.10.25. DUNLOP TYRES. These tyres are larger diameter than the standard size we use. We find that the treads still cause a considerable amount of noise. The note is higher than with the traction tread. From our experience weshould say that they are an improvement as regards non-skid qualities. Hs.{Lord Ernest Hives - Chair} | ||
