    Abstract: A tire uniformity machine having means for rotatably mounting a pneumatic tire and a test wheel on an elongated frame and wherein the outer periphery of the test wheel is held adjacent the outer periphery of the tire with a predetermined pressure. The elongated frame is hinged on each side and provided with axially rotatable means to enable the test wheel to be aligned with the buttress area or sidewall of the tire, in addition to the conventional location adjacent the tread. The test wheel is provided with strain gauges and the diameter of the test wheel with respect to the diameter of the tire is held between the limits of 1:30 and 1:4, with the ratio of 1:16 being ideal or optimum.

    Abstract: A NON-DSTRUCTIVE METHOD OF DETERMINING THE DURABLE LIFE OF A TIRE BY MEASURING THE LATERL AND RADIAL FORCE VARIATIONS EXHIBITED BY THE TIRE. A SERIES OF SIMILAR TIRES ARE MEASURED FOR THEIR FORCE VARIATIONS, AND SUBJECTED TO USAGE IN ORDER TO DETERMINE THE EFFECT OF THE FORCE VIRATIONS UPON THE DURABLE LIFE CHARACTERISTICS OF THE SERIES. THE FORCE VARIATIONS EXHIBITED BY THE TIRE ARE COMPARED TO THE DATA OBTAINED FROM THE SERIES OF TIRES IN ORDER TO NON-DESTRUCTIVELY DETERMINE THE LIFE OF THE TIRE.

    Abstract: Method of determining the weakest point in pneumatic tires comprising simultaneously subjecting each individual cord of the plies of the tire to a force of a duration and magnitude equivalent to the force to which the individual cords of the plies of the tire undergoes as it rolls through its footprint while performing at some specified vehicle weight load, inflation pressure, vehicle velocity, and acceleration. The present method is carried out by causing a sudden increased pressure, such as a pneumatic pressure, to be exerted within the pneumatic cushioning chamber of the tire at a rate of change in pressure equal to the rate of change in the force imposed upon the individual cords of the plies of the tire during one revolution of rotation. More specifically, a selected one of various combustible gases is admixed with a reactant in a concentration to provide for the above mentioned force. The combustion reaction may be monitored to determine the characteristics thereof. The reaction provides for a predetermined force to be effected at a predetermined rate within the tire chamber. The failure of a tire indicates the weakest point of the tire structure which may be a hidden defect of a gross or a minor nature.
