-6- RM{William Robotham - Chief Engineer}/IMR.6/HH.17.12.37. (i) is with Tyre pressures 30 lbs/sq.in. rear and 25 lbs/sq.in front. (2) is with Tyres 30 lbs/sq.in. front and rear. These curves are almost exactly the ideal specified by Olley and the results on the road are most satisfactory. We are also free to run at any reasonable front tyre pressures that future experience may dictate for other reasons, without upsetting our steering characteristics. Fig. 5 shows the Oldsmobile rod as rigged up and a design scheme is going forward. FIG. 5 | ||
