  • Publication number: 20060005616
    Abstract: A laboratory test for general tire durability can produce results comparable to the GM-ATE road test. A passenger tire is mounted in a test machine and run at approximately 50 mph (80 kph), at maximum rated inflation pressure, with at least 100% maximum rated radial load, with approximately 25% of the test duration being performed with lateral force comprised of approximately equal portions of right and left steering, the remainder of the test being performed without lateral force (straight portions). A test segment comprises repeating a loading cycle a plurality of times until approximately 5000 miles have accumulated, and multiple test segments are performed until 16,000 miles have been accumulated. The test is paused and the tire is visually inspected several times during the test segments, including at the end of the test.
