International Classification:

G01M 17/02

US Classification:

73146, 1521541

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.

Abstract:

A pneumatic tire (10, 40) having a belt reinforcing structure (24) located between the carcass (12) and the tread portion (20) is reinforced with an overlay belt (30) located between the belt reinforcing structure (24) and the tread (20). The overlay belt (30) has a plurality of parallel cords (32) oriented at an angle with respect to the equatorial plane (EP) of the tire. The angle of the cords (32) is between 9. degree. to 24. degree. degrees. The overlay can be used by itself or in conjunction with a pair of belt reinforcing strips (42) located radially outwardly along both axial edges (46, 48) of one of the belts (26, 28) of the belt reinforcing structure (24). The belt reinforcing strips (42) also contain a plurality of cords (50) oriented at an angle of from 9. degree. to 24. degree. with respect to the equatorial plane of the tires.
