PURPOSE: An apparatus and a method for measuring uniformity and/or dynamic balance of a tire are provided to compact structure, to determine the position of a wheel tire to a spindle in a high precision, and to enhance uniformity. CONSTITUTION: An apparatus for measuring uniformity and dynamic balance of a tire(T) comprises a spindle rotatably supported in a rigidly-supported spindle housing(110), the tire fixedly mounted on the spindle, the spindle being rotated when measurement is performed, and at least one piezoelectric force sensor mounted on a surface of the spindle housing. The piezoelectric force sensor detects a force generated by rotation of the tire as the spindle is rotated.
