| G.W. Hancock, Esq., Hotel de France, Chateauroux, Indre, France. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}1/KW.17.10.34. Series "90" Tyres. Now that 21-G-IV is in France we hope you will give us an opinion on the "90" type Dunlop tyres. We do not know whether you have any of the M.A. type treads for comparison at Chateauroux, if not we will send you some. We hope that you also have a supply of series "90" tyres, if not will you wire us to the contrary. One problem that we think may be accentuated by the "90" tread is heavy steering for shunting. One of the features of the "90" is that it has a flatter contact with the road to increase its resistance to wear. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
