| x4050 D/BP. c. Hs.{Lord Ernest Hives - Chair} BY.8/G.11.1.35. 20/25 and 40/50 HP. CHASSIS - DUNLOP TYRES. The Type 90 tyre which we have been gradually introducing, has now done sufficient mileage under the obser-vation of the Experimental Department for them to give us a complete O.K. for the use of the tyre generally, so that if and when Dunlops are ready to supply only this type of tyre, we on our part will be ready to adopt it.
