TMSI OnLEVELTM tire test machine performs multiple tire tests on a realistic flat road surface for PC and LT, with computer controlled speed, load, inflation pressure, steer angle, and camber angle, while capturing tire performance data for immediate analysis. Test reports and data are immediately available upon the completion of each test using TMSI's built-in report generation system.
