Dear Healey, Whilst we are mainly preoccupied with war work, we are running a number of prototype Experimental cars under observation. We have come up against a curious phenomenon. With the latest type of Dunlop 650 X 15 tyres, which you have supplied to us, we suffer from an annoying reaction on the steering wheel, and even on reasonably good roads. This reaction takes the form of a continuous "nibble". It completely disappears when we fit a similar new tyre of another make. We have had the trouble on quite a number of sets of tyres, so that it is not a peculiarity confined to an exceptional case. Can you send anybody over to take an interest in it? Yours sincerely, | ||
