For rolling pneumatic tires, the thermal induced effects are mainly resulted from visco-elastic behaviour of rubber parts and dissipation of stores strain energy during the cyclic deformations. It is noted that the operating conditions crucially contribute to the rubber hysteresis effect and temperature development in a rolling tire. In current study, an elaborated 3D FE model is worked up for simulating the certain inflation pressure, loading and velocity conditions for a specified radial tire. Special emphasis is given to transient temperature distribution of interior walls and tire cavities as critical zones. Compared with the experimental tests, the current study gives satisfactory results for time rate of change in temperature of tire walls and inside inflated air.

Owing to elastic and viscous characteristics embedded rubber compounds, the dissipated energy from periodic deformation is converted into heat generation and consequently, the tire may have different body temperatures for different operating conditions. In most performed investigations, just temperature distribution is considered and the mechanical behaviour of rubber parts which are highly temperature-dependent is ignored. In this study a 3D finite element model is used for evaluating the effects of loading conditions and rubber temperature on mechanical behaviour of tire. Comparing with related published works, the results of presented study have a great accuracy and can provide a comprehensive analysis to avoid the temperature related failure.
