ABSTRACT:
A method and apparatus for centering an annular tread on a pneumatic tire-casing is described. The method, preferably put into use with the apparatus, comprises mounting a casing on a wheel, locating the equatorial plane of the casing or wheel, mounting the annular tread on an axially-moveable tread expander assembly, and positioning the tread on the tread expander assembly such that its circumferential center line is located a fixed distance from and parallel to the equatorial plane of the casing or wheel. The distance between the annular tread and the casing or wheel is reduced by an amount equal to the fixed distance so that the annular tread encircles the casing and the circumferential centerline of the tread becomes coincident with the equatorial plane of the casing or wheel.
