rotational dynamics - Rolling as pure rotation

In my book the following statement was written and I didn't understand it well. Can anyone explain it in a more simple way?

Figure 11-6 suggests another way to look at the rolling motion of a wheel - namely as pure rotation about an axis that always extends through the point,P where the wheel contacts the street as the wheel moves. We consider the rolling motion to be pure rotation about an axis passing through point P and perpendicular to the plane of the figure.

I don't understand how the rolling motion of wheel which is the combination of translational and rotational motion of wheel can be expressed as pure rotation about an axis that always extends through the point,P where the wheel contacts the street as the wheel moves?
