| To CWB. from Hs.{Lord Ernest Hives - Chair} X4115 Hsl/LG20.11.26. CHASSIS 29-EE. X457 With reference to CWB1/GM19.11.26. There is no risk of high speed wobbles with the low pressure tyres on the 40/50 HP. car without front wheel brakes. We recommend that 6.75" tyres should be used. We are not recommending the 6" tyres. The front tyre pressures will have to be adjusted to auxthxx prevent the steering being too heavy. 6.75" tyres with 40 lbs. pressure should be satisfactory. There is no necessity to fit hydraulic dampers or extra friction in the pivots. Hs.{Lord Ernest Hives - Chair} | ||
