Abstract

A standardization system for the manufacture of tires is provided. The same size tire components can be used in the summit of tires having different sizes i.e., tires having different section widths, sidewall heights, and/or aspect ratios. A matrix of tire sizes can be associated with one or more tire summit parameters. The matrix can be used for the manufacture of tires having one or more standardized components by holding substantially constant the value of one or more tire summit parameters across a diagonal of the matrix.

First claim

What is claimed is:

1. A method of tire manufacture, comprising the steps of:
creating a matrix of tire sizes using tire dimensions along the axes of the matrix;
associating a tire summit parameter with corresponding pairs of the tire dimensions from both axes of the matrix;
standardizing the tire summit parameter along a diagonal of the matrix by selecting a substantially constant value for the tire summit parameter along the diagonal;
producing components for incorporation within multiples summits of multiple tires, the tires having different aspect ratios but each of the tires having the same substantially constant value of the tire summit parameter;
and
manufacturing tires having different aspect ratios using the components from the step of producing.

2. A method of tire manufacture as in claim 1 , said manufacturing step comprises:
creating tires having different sidewall heights that incorporate tread belts having the same width along an axial direction of the tire.

3. A method of tire manufacture as in claim 1 , wherein said manufacturing step comprises:
producing tires having different sidewall heights that incorporate one or more belts under a tread in the summit of the tires that have the same width along an axial direction of the tires.

4. A method of tire manufacture as in claim 1 , wherein said manufacturing step comprises:
extruding tread belts having the same width along an axial direction for incorporation into tires having different sidewall heights.

5. A method of tire manufacture as in claim 1 , wherein said standardizing step comprises designing multiple tires having different sizes that each use a component in the summit having the same width along an axial direction of the tire.

6. A method of tire manufacture as in claim 1 , wherein said standardizing step comprises designing multiple tires having different sizes that each include a belt in a summit region of the tire that has the same width along an axial direction of the tire.

7. A method of tire manufacture as in claim 1 , wherein said standardizing step comprises designing multiple tires having different sizes that each include a tread portion for the tire that has the same cross-sectional area.

8. A method of tire manufacture as in claim 1 , wherein the matrix is comprised of tire section width (w i ) along one axis and tire aspect ratio (r i ) along the other axis, wherein the tire summit parameter along the diagonal of the matrix is a tire summit width sw i , and wherein the diagonal has a slope such that an increase of about 10 mm in section width (w i ) corresponds to an increase in aspect ratio (r i ) of about 0.05 along the diagonal.

9. A method of tire manufacture as in claim 1 , wherein said manufacturing step comprises:
providing a rubber extrusion die for the manufacture of tires having different sidewall heights and aspect ratios.

10. A method of tire manufacture as in claim 1 , wherein the tire summit parameter of said step of associating is a rolling tread width of the tire.

11. A method of tire manufacture as in claim 1 , wherein the tire summit parameter is selected from the group consisting of tire section width, tread width, belt width, rolling tread width, cross-sectional area of a belt within each of the summits of the tires, volume of a belt per pitch within each of the summits of the tires, and volume of a tread portion per pitch within each of the summits of the tires.

12. A method of tire manufacture as in claim 11 , wherein the pair of tire dimensions are selected from the group consisting of section width, sidewall height, and aspect ratio.

13. A method of tire manufacture as in claim 12 , further comprising storing one or more components from the producing step prior to the manufacturing step.

14. A method for the manufacturing of tires, comprising the steps of:
producing tires with different aspect ratios and different sidewall heights that all have substantially the same tire summit width (sw i ), said producing step comprising
referencing a matrix having either tire sidewall height (h i ) or tire section width (w i ) along a first axis and tire aspect ratio (r i ) along a second axis, and having a tire summit width (sw i ) associated with each particular sidewall height (h i ) or tire section width (w i ) along the first axis and tire aspect ratio (r i ) along the second axis, and wherein the tire summit width (sw i ) remains substantially the same for a predetermined change in the value of the first axis and the second axis.

15. A method for the manufacturing of tires as in claim 14 , wherein said step of producing further comprises using tread portions in the tires that are of the same width along an axial direction of the tires.

16. A method for the manufacturing of tires as in claim 14 , wherein said step of producing further comprises using belt packages having the same width along an axial direction of the tires.

17. A method for the manufacturing of tires as in claim 14 , wherein said step of producing step further comprises extruding tread portions for the tires using an extrusion die that is the same for each of the tread portions.

18. A method for the manufacturing of tires as in claim 14 , wherein the tire summit width (sw i ) of the matrix remains substantially the same across a change of about 10 mm in tire sidewall height (h i ) and a change of about 0.05 in tire aspect ratio (r i ).

19. A method for the manufacturing of tires as in claim 14 , wherein said step of producing further comprises using a tread mold to produce tread for the tires having different aspect ratios and different side wall heights.
