Figure 5: Comparison between tyres (CycloXKing (black bar), 2.2 XKing (gray bar), and 2.4 XKing (white bar)) and three normalised tyre inflation pressures characterised as low (1), normal (2), and high (3) for (a)–(c). Total accelerations: (d)–(f). Vertical accelerations; (g)–(i). Horizontal accelerations, where refers to the interaction for tyre size tyre pressure (; ), $ refers to the interaction for tyre size accelerometer location , refers to the interaction for tyre pressure accelerometer location (); main effect of tyre size; main effect of tyre pressure; main effect of accelerometer location.
