Abstract
Method for vulcanizing a tire by predetermining a degree of vulcanization, comprising the steps of determining specified structural and dimensional parameters of the tire and of a vulcanization mould, determining the change over a time (t) of specified thermodynamic parameters of the tire, of the mould, of heat-supply fluids and of a cooling fluid, determining a parameter consisting of an equivalent vulcanization time t , and determining an equivalent degree of vulcanization X(t ) at specified points within the tire by means of an equivalent isothermal rheometric curve at a reference temperature T , comprising three consecutive sections having the following equations:
