1. A method of pre-conditioning a tire, the method comprising:
positioning the tire in a tire vice between a first mandrel and a second mandrel spaced apart from the first mandrel, the first mandrel attached to a first shaft, and the second mandrel attached to a second shaft;
moving the first mandrel and the second mandrel toward one another until a first sidewall of the first mandrel is opposing a circumferential first bead of the tire and a second sidewall of the second mandrel is opposing a circumferential second bead of the tire;
when the first sidewall is opposing the first bead and the second sidewall is opposing the second bead:
providing pressurized fluid from an air pressure source to an internal cavity of the tire via a slip sleeve defined by the first shaft or the second shaft, wherein providing pressurized fluid to the internal cavity of the tire burnishes excess tire material from the first bead and the second bead as the first bead moves relative to the first mandrel while in contact with the first sidewall and the second bead moves relative to the second mandrel while in contact with the second sidewall;
moving at least one of the first mandrel or the second mandrel away from the other of the first mandrel or the second mandrel; and
removing the tire from the tire vice.
