Direct address laser ablation

A method for reducing one or more harmonics of at least one uniformity parameter in a tire, comprising:

• receiving a plurality of ablation patterns for a bead of a tire, each ablation pattern associated with a different track location on the bead of the tire in a bead seat, low flange zone and high flange zone, each ablation pattern defining a desired ablation depth relative to an angular location around the bead and calculated to correct for one or more harmonics of at least one uniformity parameter for the tire;
• identifying a plurality of addresses for the bead, each address being associated with a specific angular location on the bead of the tire;
• analyzing each ablation pattern to determine a plurality of direct address commands to achieve the plurality of ablation patterns, the plurality of direct address commands specifying ablation parameters for a plurality of discrete ablation segments at one or more of the plurality of addresses along the bead of the tire, the discrete ablation segments arranged in a plurality of discrete layers;
• controlling the ablation device to selectively remove tire material from the bead in discrete ablation segments pursuant to the direct address commands to achieve the plurality of ablation patterns;
• wherein the tire material is selectively removed to achieve the plurality of ablation patterns using a single pass of the ablation device around the bead.
