T = w • f
T = Total Kingpin Torque required to steer axle.
W = Vehicle Weight supported by the steered axle.
f = Coefficient of friction (dimensionless). Based on 0.7 as a
Maximum. Determine from chart at left.
B = Nominal width of the tire print (see diagram above).
E = Kingpin Eccentric (use nominal tire width).
