Abstract
Methods and systems for improving the uniformity of a tire are provided. More specifically, one or more characteristics of a composite uniformity parameter can be determined from uniformity summary data (e.g. uniformity vectors) associated with a plurality of harmonics of the composite uniformity parameter. For instance, a peak to peak range of a composite uniformity parameter and/or a distribution of amplitudes of a composite uniformity parameter for a set of tires can be determined from uniformity vectors associated with selected harmonics of the composite uniformity parameter. According to example aspects of the present disclosure, the one or more characteristics of the composite uniformity parameter can be determined using multivariate normal distributions (e.g. bivariate normal distributions) of the uniformity summary data. Once identified, the one or more characteristics can be used to modify tire manufacture to improve tire uniformity.
