Comparison of Dynamic Testing Equipment and Test Methods for Tire Tread Compounds
This study is to evaluate various tire tread compounds for dynamic properties and crack growth properties. Properties such as E*, G* and Tan 𝛿 are evaluated in compression and shear, using different specimen geometry, over wide ranges of temperature and strain. Four compounds (three tire tread compound and one seal compound) are tested for dynamic properties and crack growth performance. No attempt was made to optimize any of the properties. Correlation of dynamic testing equipment and test methods are shown. Dynamic testing equipment used in this study are the Rubber Process Analyzer 2000 (RPA), Dynamic Mechanical Analyzer (DMA) and MTS 831.20 Elastomer Test System (MTS)A Methodology of Life Prediction of Tires.
