Method for the production of tyres

Method for designing a tyre comprising a plurality of structural parts which are different from each other in terms of size, composition or position within the cross section of said tyre, which includes the steps of defining at least one profile of said tyre on the basis of a group of predefined dimensional constraints, defining remaining profiles on the basis of correlations between dimensional values of said structural parts, defining within the cross section the shape of said structural parts, filling each shape with a basic component depending on the composition of the structural part defined by said shape.
