| W/S Sp.{Mr Spinney} from Hs.{Lord Ernest Hives - Chair} Y3538 Hs{Lord Ernest Hives - Chair}7/LG5.12.21. TYRE PRESSURES. We have not yet received a completed list of tyre pressures from the Michelin Co. You will remember we recommended certain pressures for the lower weight per tyre than they gave in their list. Can you do anything to urge this? The list of tyre pressures agreed to by the Michelin people are, so far, lower than any other tyre maker. We are anxious that we should try and get all tyre makers into line. As soon as we get the Michelin pressures, we intend to try and get their agreement so that we have one standard set of tyre pressures. Hs.{Lord Ernest Hives - Chair} | ||
