System for characterizing tire uniformity machines and methods of using the characterizations

摘要

A tire uniformity machine includes an apparatus for receiving and rotating a tire. The apparatus includes opposed spindles for receiving, inflating and rotating a tire, and a load wheel applied to the rotating tire to obtain tire test results. A spindle alignment assembly is associated with the opposed spindles to align the spindles with one another each time a tire is received. At least one characterizing device is associated with components of the apparatus to characterize forces of the opposed spindles and the characterized forces are used in adjusting tire test results.
