Abstract

A method of preparing a tire for mounting includes providing a tire having a central axis and at least two bead portions, including a first bead portion and a second bead portion. The method also includes providing a plurality of members and moving the plurality of members outward until each of the plurality of members engages the first bead portion of the tire and causes the first bead portion to deflect outwards at a plurality of locations. The method further includes rotating at least one of the tire and the plurality of members about the central axis of the tire while the plurality of members engages the first bead portion of the tire.

First claim

What is claimed is:

1. A method of preparing a vulcanized tire for mounting on a wheel, the method comprising:
providing a vulcanized tire having a pair of bead portions, including a first bead portion and a second bead portion;
providing a plurality of tire engaging members comprising oppositely disposed telescopic arms;
moving the plurality of tire engaging members outward, such that a radially outward force is applied to the first bead portion at a plurality of locations and the first bead portion deflects outward by a distance of 5 to 10 centimeters; and
rotating the plurality of tire engaging members in a first direction about a central axis of the vulcanized tire, such that each of the tire engaging members moves relative to the vulcanized tire while engaging the first bead portion.

2. The method of claim 1 , wherein the plurality of tire engaging members includes two rollers.

3. The method of claim 1 , wherein the plurality of tire engaging members includes four rollers.

4. The method of claim 1 , wherein the moving the plurality of tire engaging members outward includes moving the plurality of tire engaging members into engagement with both the first bead portion and the second bead portion of the vulcanized tire.

5. The method of claim 1 , further comprising rotating the vulcanized tire in a second direction about the central axis of the vulcanized tire, the second direction being opposite the first direction.

6. The method of claim 1 , wherein the radially outward a force is between 110 Newtons and 3500 Newtons.

7. The method of claim 1 , wherein the rotating the plurality of the tire engaging members causes a deflection at each point of contact between each tire engaging member and the first bead portion.

8. A method of preparing a vulcanized tire for mounting, the method comprising:
providing a vulcanized tire having a central axis and at least two bead portions, including a first bead portion and a second bead portion;
providing a plurality of members;
moving the plurality of members outward until each of the plurality of members engages the first bead portion of the vulcanized tire and causes the first bead portion to deflect outwards at a plurality of locations by a distance of 5 to 10 centimeters; and
rotating the vulcanized tire and the plurality of members about the central axis of the vulcanized tire while the plurality of members engages the first bead portion of the vulcanized tire, such that the plurality of members rotates relative to the vulcanized tire.

9. The method of claim 8 , wherein the moving the plurality of members outward includes moving the plurality of members outward until each of the plurality of members engages the second bead portion of the vulcanized tire and causes the second bead portion to deflect outward at a plurality of locations.

10. A method of claim 8 , further comprising rotating each of the plurality of members about its own axis.

11. The method of claim 8 , wherein the moving the plurality of members outward includes moving the plurality of members with telescopic arms.

12. The method of claim 8 , wherein rotating the vulcanized tire and the plurality of members about the central axis of the vulcanized tire causes a deflection at each point of contact between each member and the first bead portion of the vulcanized tire.

13. The method of preparing a vulcanized tire for mounting on a wheel, the method comprising:
providing a vulcanized tire having a central axis;
providing a plurality of rollers;
moving each of the plurality of rollers into contact with at least one bead portion of the vulcanized tire such that each of the plurality of rollers applies a radially outward force to the at least one bead portion and causes an outward deflection of between 5 and 10 centimeters;
rotating the plurality of rollers about the central axis of the vulcanized tire; and
rotating the vulcanized tire about the central axis relative to the plurality of rollers, while each of the plurality of rollers continues to apply a radially outward force to the at least one bead portion and cause an outward deflection.

14. The method of claim 13 , wherein the rotating the vulcanized tire is performed by a wheel configured to engage a circumferential tread of the vulcanized tire.

15. A method of claim 14 , wherein the wheel is further configured to apply a radially inward force to the vulcanized tire.

16. The method of claim 13 , wherein the radially outward force is between 110 Newtons and 3500 Newtons.

17. The method of claim 13 , wherein rotating the plurality of rollers causes a deflection at each point of contact between each roller and the at least on bead portion.
