| contd :- -4- nibbles do not cause discomfort, but they are not nice. If a tyre has a tendency to wobble either due to out of balance or out of truth, these nibbles become rather irritating. Steering selectiveness is rather better than standard with 2500 lbs. springs, especially on highly cambered roads. On moderately good roads there is little to choose between two side steering tube arrangements for road shocks. On really bad roads as would be expected, the new arrangement of side steering tube springs is a very marked improvement, cutting out all the actual discomfort and violent steering wheel movements. SUMMARY. It will therefore be seen that the present arrangement of side steering tube is preferable for British conditions while the experimental arrangement gives the best results for Continental roads. We are endeavouring to determine the best compromise for all round conditions and are trying out something on the lines of graph C. The idea of this is that a very small initial set up and a large initial rating (due to the opposed springs) provides the control. This should cut down the transmission of small shocks to a minimum and also absorb large shocks on the low rating portion of the deflection. Hs{Lord Ernest Hives - Chair}/W.
