Abstract
Modifiable molds, methods and systems are provided for optimizing force variation harmonics in concert with the intentional variation of elements to attain an overall average aligning force.
Claims26
A mold for modifying force variation harmonics in a tire having a tread formed from the mold, comprising:
- an arrangement of tread-molding elements including at least one of one or more removable tread-molding elements and one or more alternative removable tread-molding elements and defining at least one tire pitch sequence;
- wherein the tread-molding elements are selectively arranged to effect adjustment of the at least one tire pitch sequence to achieve an overall target harmonic distribution for the arrangement.
The mold of claim 2, wherein the plurality of tread-molding elements defines a total plysteer contribution of the mold and includes at least one of:
- one or more removable tread-molding elements with each element having a predetermined plysteer contribution;
- and
- at least one alternative removable tread-molding element having a predetermined plysteer contribution that differs from the predetermined plysteer contribution of the one or more removable tread-molding elements.
