Motion of tyres around a Circular Path

Question :: What is the motion of tyres around a circular path and explain about their velocities?

Solution :: The motion of different tyres can be understood by taking different examples
1.) 2 - wheeler
2.) 3 - wheeler
3.) 4 - wheeler

1.) 2 - wheeler
      When a 2- wheeler is going around a circular path then the tyres will be moving in a circular path with equal radii, but the weight of the body creates a net torque when moving in a circular path.

2.) 3 - wheeler
       When a 3 - wheeler is going round in a  circular path then the tyres tend to rotate in different radii, the rear wheel which is close to the turning will move in a smaller radius when compared to the front wheel, another wheel on the rear side. The three wheels rotate in three different radii and the 3 tyres move with different velocities. The three velocities can be varied by a shaft and gears connecting  them.

3.) 4 - wheeler
    This is similar three wheeler on the rear side but the front side is behaving same as the rear side, the wheels near to the circular arc tend to rotate with smaller radius there by smaller velocities compared to the wheels which are away from the circular turn. The speeds of the tyres can be varied by a differential gear attached to the shaft.
