MECHANICAL CHARACTERISTICS OF TRUCK TIRES DURING COMBINED SLIP. FINAL TECHNICAL REPORT

Combined slip testing of three heavy-truck tires using the UMTRI mobile tire tester was accomplished. The testing constituted a pilot activity to investigate the influence of test induced wear and to try to establish an appropriate test matrix for combined slip testing. Data indicated that the work done on the tire during testing had a significant influence on measured behavior. The expected change in traction behavior due to test-induced wear is clearly illustrated. There is also evidence that short-term work history (i.e., insufficient to cause significant wear) can significantly influence traction behavior. The findings of this project have implications for future efforts. There is clearly a need to modify the Mobile Tire Tester to allow the efficient conduct of testing in a manner less sensitive to the test-induced wear process. The results of this work have been shared with the members of the SAE Truck Tire Task Force and used to prepare a work plan for further tire testing.
