TYRE NOISE - Cx {Major Len W. Cox - Advertising Manager} 3/KW8.12.36. With reference to the tyre noise on GUL-1, we have been trying some of those Dominion tyres with cuts in the tread; these are surprisingly silent, and offer quite a good resistance to skidding. We suggest that you run some of them on GUL-1 until Dunlops are able to produce something better than their present standard tyre. Rm. {William Robotham - Chief Engineer} Full Title of Tyre - Royal Master Centipede Tread. | ||
