Abstract: This is the second paper in a three-part study presenting an analytical approach for determining tyre dynamic properties. In this study analytical formulations are derived for the tyre dynamic properties as functions of the slip ratio, slip angle, camber angle and other tyre dynamic parameters. There formulae can be used for the general vehicle simultaneous in braking/traction and steering manoeuvres with a varying camber angle are regular or irregular terrains. In this paper the lateral force and self-aligning torque due to both slip and camber angles are first studied. The longitudinal, lateral forces and self-aligning torque during braking/traction and steering without any camber angle or with a varying camber angle are also analysed. Also, both the friction eclipse concept and the friction circle concept are investigated.
