Newtons 1st Law

Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.

Basically, when the tire spins, the molecules making up the tire want to go in a straight and outward direction. Being fused, they are pulled back to change in direction but not without expanding outwards first.

Think of it as a washer on a string, when you swing it in a circle the washer goes as far outward as the string will let it, just like the top of the tread goes as far as it can in an outward direction just like the washer does when you spin it.

Fransisco.....
Centripetal force should not be confused with centrifugal force. The centrifugal force is a fictitious force that arises from being in a rotating reference frame. To eliminate all such fictitious forces, one needs to be in a non-accelerating reference frame, i.e., in an inertial reference frame. Only then can one safely use Newton's laws of motion, such as F = ma.

Centripetal force should not be confused with central force, either. Central forces are a class of physical forces between two objects that meet two conditions: (1) their magnitude depends only on the distance between the two objects and (2) their direction points along the line connecting the centres of these two objects. Examples of central forces include the gravitational force between two masses and the electrostatic force between two charges. The centripetal force maintaining an object in circular motion is often a central force.

....the above was borrowed from wikipedia

spin yourself in an office chair. really fast. what do your legs want to do? they want to fly out. same thing. the centrifugal force, spinning force, throws everything from the center out.
