A tire pre-conditioning system includes a first mandrel, a second mandrel spaced apart from the first mandrel, and a controller in communication with the first mandrel and the second mandrel. The first mandrel is fixedly attached to a first shaft and including a first tapered sidewall. The second mandrel is fixedly attached to a second shaft and including a second tapered sidewall. The controller is operable to axially move the first mandrel and the second mandrel toward one another until the first and second tapered sidewalls are opposing respective beads of a tire, and supply pressurized fluid into an internal cavity of the tire to inflate the tire. The inflating causing the beads to move relative to mandrels while contacting the opposing respective tapered sidewalls to burnish the beads of the tire.

A honing tool holder that provides a capability for automatically feeding the honing elements or stones when in the bore of a work piece, and for automatically stopping the feeding when a particular condition such as a bore size, is reached, so as to enable use of an in-process adjustable feed honing tool in a machine tool, machining center, or the like, lacking a feed mechanism or system. The holder can also include apparatus to automatically prevent feed past a limit. Both the feed force and feed limit can be adjustable, including by simple movements of the tool holder by the machine tool.

A cylinder bore including an inner surface including an axial travel area and an axial non-travel area including two discontinuous axial widths of the cylindrical bore and the axial travel area extending therebetween. A nominal diameter of the axial travel area is greater than that of the axial non-travel area. A plurality of annular grooves is formed in the two discontinuous axial widths of the cylindrical bore.

A tire pre-conditioning system for conditioning a bead of a tire includes a burnisher and a controller. The burnisher is attached to a shaft. The controller is in communication with at least one of the burnisher or the tire. The controller is configured to move one of the burnisher or the tire until the burnisher is opposing the bead of the tire. The controller is also configured to 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.
