| W/S. Cx.{Major Len W. Cox - Advertising Manager} from Rm.{William Robotham - Chief Engineer} /339. Rm{William Robotham - Chief Engineer}15/R.6.1.37. PHANTOM III TYRE NOISES. With reference to Cx{Major Len W. Cox - Advertising Manager}10/ES.5.1.37., it is unfortunate that this car is still bad for tyre noises. Of course, as the tyres wear the noise will become worse until it reaches a maximum, and as the tyres get smoother it will get less. Dunlops are on the job making us various modified treads, and if these show any promise we will let you have a set. Rm.{William Robotham - Chief Engineer} | ||
