ABSTRACT:
Differential expansion (or contraction) of areas of a tire sidewall is measured by constructing height profiles of the tire at each of at least two different static pressures to detect defects in the tire. Light sources project a plurality of illuminated lines onto a tire and cameras are used to record the position of the lines to construct the height profiles of a rotationally fixed position tire.
