“…Considering the tire as a thermo-mechanical system, as already described in Farroni and colleagues, 4,10 in addition to the conductive mechanisms within the composite structure due to the temperature gradients, the following heat transfer mechanisms have been taken into account: Heat generation terms connected with the friction phenomena arising at the interface with the asphalt pavement and the stress-deformation cycles of the whole tire mass during the operation: Tire-road longitudinal-lateral interaction generation, known as ''FP'' (friction power), concerning the contact patch extension and directly connected with thermal powers as a function of global tangential interaction forces and the relative sliding velocities between the tire surface and the uneven asphalt; Effect of tire cyclic deformation and recovery, known as ''SEL'' (strain energy loss), associated with the tire rolling resistance and the operating phases with significant values of interaction forces and, thus, structural internal deformations; Heat exchange with the external environment (as said the radiation mechanism is neglected by hypothesis) due to: Thermal conduction between the tire tread and the road pavement, as a function of the compound thermal characteristics; Forced convection of the surface layer with the outside air and of the innerliner surface with the inner gas, both described by Newton's law of cooling, whose magnitude is dependent on the value of the relative velocity of surface nodes and air flux, evaluated by means of CFD simulations. 21,22 The TRT EVO model is able, by means of tread subdivision in ribs, to describe the inhomogeneous distributions of local variables within the contact patch, as stresses or deformations due to specific working conditions of the wheel and thus of the tire. This has become necessary to study different suspensions solutions, characterized by different wheel alignment angles and contact patch shapes and extensions.…”

“…Recently, many works have included climatic conditioning to classical studies conducted in wind tunnels. [11][12][13] Therefore, this paper is a research activity that is necessary for the development of such additional and relevant features, and that could help other researchers willing to do the same.…”
