Unbalanced forces act on an object when the net force acting on it is not zero. In this case, the correct situation where unbalanced forces are acting on the tire is:

Two people stand on the same side of a large tire. One person pushes the tire and the other pulls the tire with equal force.

In this scenario, the forces are acting in opposite directions, and since one person pushes while the other pulls, the forces do not cancel each other out completely, resulting in an unbalanced force on the tire.

Inertia is defined as:

an object’s resistance to a change in its motion.

This means that an object at rest will remain at rest, and an object in motion will continue moving at a constant velocity unless acted upon by an external force.
