Tyres for the SpectreCodename for Phantom III. We have had considerable trouble with tyre noise at low speeds on SpectreCodename for Phantom III cars. This appears to have been accentuated to a certain extent by independent wheel springing. The Dunlop tyres are particularly bad in this respect. The only other English made tyre which we have test is the India, which is certainly much better, though far from perfect. We appreciate that as a matter of policy it may be preferred to fit Dunlops to the cars at the Show, and also to demonstrate on Dunlops. It will, however, be some time before we can get them to bring their product into line with that of India in regard to this particular fault. Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} | ||
