The present invention relates to a method for quantitatively evaluating the grip and balance of an automobile tire. A computer for evaluating the gripping force and balance performance of an automobile tire receives data on steering angle and steering torque from a steering force while a high lateral acceleration steering sweep test is performed, and angle meter and data on 3-axis acceleration, lateral acceleration, and 3-axis angular velocity from an inertial sensor, and extracts objective performance factors relative to the gripping force and balance performance of the tire based on the measured data received from the steering force and angle meter and the inertial sensor. Also, the computer checks the gripping force and balance performance of the tire based on the extracted objective performance factors. Thus, the present invention can solve the problems of not reflecting subjective evaluation results caused by the previous objective evaluation method, and can evaluate the gripping force and balance of the tire without complex objective performance factors, thereby being efficiently applied to the development of tire.
