Abstract

A system and method for reducing the magnitude of one or more harmonics of one or more uniformity parameters in a cured tire involves selective removal of tire material at one or more track/area locations along first and second bead profiles. Selective removal may occur via ablation at the bead seat, low flange and/or high flange zones to correct for a selected number of harmonics of such parameters as radial, lateral and tangential force variation. Ablation patterns are calculated and implemented on first and second tire beads to achieve desired levels of force reduction at selected angular locations (within the expanse from 0-360 degrees along each tire bead). Ablation patterns may be calculated for implementation at fixed or varied tire rotational speeds and/or fixed or varied levels of laser power.
