Patent ID: 7780891

Claim:
A method for making a plurality of tire molds for a plurality of tires, the method comprising the steps of: selecting a first major axis length of a first ellipse extending laterally between a first shoulder region and a second shoulder region in a first tire mold for a first tire; selecting a ratio of the first major axis length of the first ellipse to a first minor axis length of the first ellipse; forming the first tire mold having a profile with the first major axis extending laterally between the first shoulder region and the second shoulder region of the first tire mold and the selected ratio; selecting a second major axis length of a second ellipse extending laterally between a first shoulder region and a second shoulder region in a second tire mold for a second tire, wherein the second major axis length is different from the first major axis length; and forming the second tire mold having a profile with the second major axis extending laterally between the first shoulder region and the second shoulder region of the second tire mold and the selected ratio, such that the ratio of the second major axis length and a second minor axis length of the second ellipse is equal to the ratio of the first major axis length and the first minor axis length of the first ellipse.
