System and Method for Pre-Conditioning Pneumatic Tires Prior to Mounting Same Onto a Wheel

1 . A tire pre-conditioning system for conditioning a bead of a tire, the tire pre-conditioning system comprising:

a burnisher attached to a shaft; and

a controller in communication with at least one of the burnisher or the tire, wherein the controller is configured to:

move one of the burnisher or the tire until the burnisher is opposing the bead of the tire; and

supply pressurized fluid into an internal cavity of the tire to cause the bead to contact the burnisher to burnish the bead of the tire.

2 . The tire pre-conditioning system of claim 1 , further comprising:

a linear actuator in communication with the controller and the shaft, wherein the linear actuator is configured to move the shaft in a direction; and

a rotary drive unit in communication with the controller and the shaft, wherein the rotary drive unit is configured to rotate the shaft.

3 . The tire pre-conditioning system of claim 1 , further comprising:

an air pressure source in communication with the controller, wherein the air pressure source is configured to supply the pressurized fluid to the internal cavity of the tire to inflate the tire when the burnisher is in contact with the bead.

4 . The tire pre-conditioning system of claim 1 , wherein the burnisher includes a sidewall that is at least one of roughened or includes one or more abrasive materials.

5 . The tire pre-conditioning system of claim 4 , wherein the abrasive materials are impregnated within the burnisher.

6 . The tire pre-conditioning system of claim 1 , wherein an exterior surface of the burnisher is roughened.

7 . The tire pre-conditioning system of claim 1 , wherein the burnisher includes a circumferential burnishing region defined by a series of apertures formed through the burnisher.

8 . The tire pre-conditioning system of claim 7 , wherein one or more apertures of the series of apertures is defined by cambered walls configured to shave off excess tire material.

9 . The tire pre-conditioning system of claim 1 , further comprising:

a circumferential axial stop radially protruding from the burnisher, wherein the axial stop is configured to limit axial movement of the tire when the burnisher contacts the bead of the tire.

10 . The tire pre-conditioning system of claim 1 , wherein the shaft includes a slip sleeve configured to direct the pressurized fluid from an air pressure source to the internal cavity of the tire.

11 . A method of pre-conditioning a bead of a tire, the method comprising:

positioning the tire proximate a burnisher;

moving at least one of the tire or the burnisher toward the other of the tire or the burnisher until a surface of the burnisher is opposing the bead of the tire;

providing pressurized fluid from an air pressure source to an internal cavity of the tire to urge the bead against the burnisher and remove tire material from the bead as the bead contacts the burnisher; and

moving one of the tire or the burnisher away from the other of the tire or the burnisher.

12 . The method of claim 11 , wherein the bead of the tire defines a tire opening.

13 . The method of claim 11 , wherein the tire is an uninflated tire.

14 . The method of claim 11 , further comprising:

after inflating the tire with the pressurized fluid, rotating one of the tire or the burnisher to remove tire material from the bead.

15 . The method of claim 11 , further comprising:

prior to moving one of the tire or the burnisher, deflating the tire by opening an air release valve disposed in an air conduit.

16 . The method of claim 11 , wherein the burnisher includes a sidewall that is at least one of roughened or includes one or more abrasive materials.

17 . The method of claim 11 , wherein the burnisher includes a sidewall that define a circumferential burnishing region including a series of apertures.

18 . The method of claim 11 , wherein the burnisher includes a sidewall that includes a circumferential axial stop protruding at least partially radially outward from the sidewall.
