| - 2 - As regards "front jellying", the new type radiator suspension certainly made this defect less obviously objectionable. The opportunity of making these tests on French roads with their varying surfaces and speed conditions was most impressive. We were able to make some most interesting and convincing tests on effect of tyre pressures. Reducing tyre pressures reduced the "jar" and "dithering", but with low rear tyre pressures steering is most unstable and wanders. Low front tyres set up steering wobble periods. The best compromise is 30 lbs. front and rear. It has brought home to me the fact that most of our steering complaints may be due to tyre pressures. As regards steering "joggles", this I considered the worst feature. I also appreciated the necessity of the steering being light and free. I certainly now take the view that to reduce the freedom would be a retrograde step. EP. {G. Eric Platford - Chief Quality Engineer} EP. {G. Eric Platford - Chief Quality Engineer} P.S.
