Abstract

Process and apparatus for improving a concentricity of a pneumatic vehicle tire having a bead. The process includes subjecting at least a portion of the bead, after vulcanization, to a plastic deformation post-treatment. The post-treatment improves the concentricity of the tire. The apparatus includes a drum having a surface which engages a radially inner bead seat surface of the tire. The drum includes at least one of an internal heating mechanism and an internal cooling mechanism. The drum is adapted to plastically deform at least a portion of the bead of the tire so as to affect at least one of a first, a second, and a third harmonic. The plastic deformation improves the concentricity of the tire.
