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 | ||
