Eric Platford - Chief Quality Engineer}/Thm2/H7.11.22., that we might with advantage lower our tyre pressures even below those outlined in the Dunlop Company's booklet entitled "The care of Tyres", the Dunlop Company have now written us fully on the matter as copy attached, from which it will be observed that they do not recommend any reduction in their present recommendations. Will you kindly advise us if you have any comments to make thereon. As the Dunlop Company have only sent us two schedules will EP{G. Eric Platford - Chief Quality Engineer} kindly pass same on to the other departments after perusal. We have advised the Dunlop Company that the pressures to which we refer are those appearing in the later edition of their booklet, supplies of which were issued to all concerned on 17th July, 1922.
