摘要： An apparatus and technique for measuring and analyzing the tread wear of a pneumatic tire. The tire is indexed about its axis. Between the indexing steps, a laser scanner obtains data from the tread surface. This data is normalized to eliminate any out-of-roundness of the tire data. Noise spikes are removed and replaced with values attributable to valid data. From the data, a reference curve corresponding to a lateral sector of the tire is devised. The data from actual lateral sectors is then compared to the reference curve by a curve-fitting process and the deviation between the actual data and the reference curve establishes the degree of irregular wear of the tire at that lateral point.
