Summary:

Knowledge of the deformation amplitude of the tire components during the actual running is important in the analysis of the fatigue process of the tire components. Attempts to imbed strain gauges in the tire carcass to measure the deformation met difficulties due to the alteration of carcass properties in the process of imbedding the strain gauges.In this article, we describe an attempt to estimate the tire deformation in operation from the data of temperature rise. Measurement of the temperature rise is considerably easier than the measurement of the deformation. The temperature data are analyzed by considering the dynamics of self-heating which includes the heat generation rate terms. From the temperature rise, the corresponding heat generation rate is determined and then this is translated to the corresponding deformation of tire components by use of the data of viscoelastic hysteretic loss of the components which are determined in laboratory in advance by use of a high strain dynamic viscoelastometer.Examples of the analysis are illustrated. The deformation determined by this procedure shows consistent correlations with the load, speed and carcass modulus
