I have 2 doubts . First one was to figure out how the positive and negative scrub radius will affect the dynamic toe during braking or accelerating . Then it made me realise that to understand this I will have to analyse all the forces acting on the tire (tractive forces) . Then i read up rolling resistance , deformation of tire , hysteresis etc. . But it is not too clear , could you please explain the forces in play between the tire and the road during steady motion , acceleration and deceleration . Vector force diagrams will be of great help . Thanks .
