1. A tire pre-conditioning system comprising:
a first mandrel attached to a first shaft, the first mandrel including a first sidewall;
a second mandrel attached to a second shaft, the second mandrel including a second sidewall; and
a controller in communication with the first mandrel and the second mandrel, the controller operable to:
move the first mandrel and the second mandrel toward one another until the first sidewall of the first mandrel is opposing a first bead of a tire and the second sidewall of the second mandrel is opposing a second bead of the tire, and
supply pressurized fluid into an internal cavity of the tire for causing the first bead to move relative to the first mandrel while contacting the first sidewall to burnish the first bead of the tire, and the second bead to move relative to the second mandrel while contacting the second sidewall to burnish the second bead of the tire.
