| COPY. RE TYRES. BY.{R.W. Bailey - Chief Engineer} D/Sn{Mr Sanderson}13/AW4.5.20. We are advised by Sales Department that Mr. Schuette has written them saying he has compared the Dunlop 895 x 150 tyres, as shipped on a recent chassis, with their standard tyres, 33 x 5, and finds that the American tyre measured at least one inch larger in every way than the oversize Dunlop. Sales Department think you will be interested to know this. Sn.{Mr Sanderson} | ||
