Systems and methods for analyzing tread surface data to assess tire tread parameters, such as irregular wear characteristics of a tire tread, are provided. For example, tread surface data, such as a tread surface map, can be processed to generate a convex hull for the tire. The convex hull can approximate the convex outer surface of the tire. The convex hull can be used as a reference for analyzing the tread surface data. In particular, irregular wear zones in the tire tread can be mathematically concave relative to the convex hull. Comparing the tread surface data to the convex hull can reveal information indicative of irregular wear characteristics of the tire. For instance, the local depth of the measured tread surface data relative to the convex hull can provide a quantitative measure of irregular wear characteristics of the tire.
