The third number generally preceded by an "R" is the wheel diameter. The wheel diameter d w [mm] is the sum between the rim diameter and twice the height of the tire: \[d_{w} = D + 2 \cdot H \tag{3}\] The (free static) wheel radius r w [mm] is half the wheel diameter: \[r_{w} = \frac{d_{w}}{2} \tag{4}\] To take into account the deformation of the tire, we can apply a coefficient of 0.95, which means that the free static radius will decrease with approx. Wheel graphs are Planar graphs. 0000011680 00000 n l8HsuM\����3��ݨO4��7��i�:M�L��Di��^�w If the two wheels are front and rear wheel, both distances should be equal.
