Patent ID: 7133736

Claim:
A method for designing a tyre, comprising: defining at least one profile of the tyre based on a group of predefined dimensional constraints; defining at least one additional profile of the tyre based on predefined dimensional values of structural parts of the tyre; defining, within a cross-section of the tyre, shapes of the structural parts of the tyre; and approximating each shape by filling with a respective basic component depending on a function of the respective structural part; wherein the tyre comprises a plurality of the structural parts, wherein each of the structural parts comprises one of the basic components, wherein at least some of the structural parts are different from each other in terms of composition, position within the cross-section of the tyre, or one or more dimensions, wherein one of the structural parts comprises at least one carcass ply disposed within the cross-section of the tyre along a predefined profile, and wherein the cross-section of the tyre is defined by a radially-external profile and a radially-internal profile.
