A system for detection of non-pneumatic tire loading includes a non-pneumatic tire. The non-pneumatic tire includes a ground-contacting annular tread, a central rim, and at least one spoke disk disposed between the rim and the tread. The spoke disk includes an inner ring mounted on the central rim, an outer ring, and spokes extending radially between the inner ring and the outer ring. A shear band is disposed between the outer ring of the spoke disk and the tread. A flange is disposed on an outboard surface of the spokes of the spoke disk. Indicating means are formed on the outboard surface of the plurality of spokes of the spoke disk radially outwardly of the flange. The flange interfaces with the indicating means when the tire is in an overloaded state or is in need of replacement.
