| -2- why you should get a 28% improvement from 50 to 70 m.p.h. We know it is impossible, and the only satisfactory way of making that test would be to change the cylinder heads on that car. To compare the results with a previous car is not of much value. We have now either to try and find an explanation, which we cannot do, as regards why it is 28% improvement, or else say that this is not right, Tyre Wear. We should require some confirmation before we accepted the view that the light springing had anything to do with tyre wear. What evidence is your remark based upon?
