The report describes the detailed data processing and analysis of the measurement of tire profiles using a tire profilometer in an accelerated tire wear study. To obtain a more accurate measurement of tire wear, a system of hardware and software, called a tire profilometer, was developed by the Davidson Laboratory. This system included a laser depth gauge and read-out device, a tire/laser mounting platform and position locator, a strip-chart recorder, an analog-to-digital converter, an incremental digital magnetic tape recorder and controller, and the computer programs to read and help analyze the data on these tapes. This system is applied to three tires with mixed success, but considering the newness of the digital recording and analysis technique in application to tire profile descriptions the agreement between the digital, the analog and the traditional plunger is encouraging.
