| - 3 - this account, and in view of the experience of the Rolls-Royce and other users, it would be probably premature to take for granted that the tyres are necessarily unsatisfactory. We, therefore, recommend that a further experiment be made by running the tyres definitely at the pressures recommended by the Rolls-Royce Co., viz., 35 lbs front and 40 lbs rear, for two or three weeks, when Mr. Antweiler may then favour us by reporting any modification of his experience. We will be glad to assist in maintaining this pressure by testing and keeping it right as often as the driver cares to call at our Livery Street Depot. The driver himself can also check from time to time by means of the satisfactory gauge which has been given to him. Of course, we quite appreciate that any car owner who dislikes his tyre equipment is entitled to purchase another kind of tyre equipment if he wishes to, but we feel that it would be a pity and probably not in accordance with Mr. Antweiler's desires to do so on the grounds that the present tyre equipment is not satisfactory, in view of the facts and experience detailed above.
