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.
