You could look at the sidewall as a arched leaf spring, where the end points are fixed, but compressed closer together. The entire spring flexes, but in the case of a tire, the area near the wheel is much, much stiffer than the rest of the sidewall.
you have seen a leaf spring?
the loop at the end is in fact a hinge
the junction between the sidewall and the tread
is the same

in fact the tires of the moon buggy work exactly like that
