Abstract

This work proceeds from the idea that the air pressure in the tire is the preponderant component of elasticity. It is possible to construct a simple relationship between the stress and the reduction of the volume after deformation from the equivalence of the work of the deforming load to the work done on the air content of the tire. The description of the procedures for calculating the volume in the case of belted tires forms the essential portion of the present report. A comparison is given between calculated and measured deformation characteristics and results of measurements of pressure in deformed, belted tires.
