Abstract: Systems and methods for improving tire uniformity, for instance to reduce cavity noise and other effects caused by localized tire surface anomalies are provided. The localized tire surface anomaly can be manifested as a local peak of radial nm out or other uniformity parameter (e.g. radial force variation) for the tire. The local peak of radial run out can be within uniformity tolerances for radial run out, but can still contribute to cavity noise through the high harmonic effects caused by the local peak. According to aspects of the present disclosure, the location and/or other identifiable characteristics of a localized tire surface anomaly can be identified. An ablation device can be used on the tread of the tire to remove tire material at an azimuthal location associated with the localized tire surface anomaly to improve the uniformity of the tire.
