CTWIST is used in tire development centers and test tracks to support new tire development programs since tire designers are challenged to develop new tread patterns and compounds that deliver longer tread life and more uniform tread wear. Selected by Ford Motor Company as their standard tread wear measurement platform for their OEM suppliers. CTWIST predicts the tread life for each rib and produces several tread wear reports to help the designer understand where improvements are needed. The CTWIST method permits tread life to be accurately predicted by running the tires only a small percentage of their lives, thus saving the time and cost of tire testing.
