1/ Tire load is found by multiplying the value given in the table by the nominal tire width.
Interpolation of table values is allowed.
4.9.1.4 Separation (drum) test.
4.9.1.4.1 Apparatus. To determine conformance to 3.5.5, the testing apparatus shall be
the same as that specified in 4.9.1.3.1.
4.9.1.4.2 Procedure. The tire, mounted on a hub and spindle assembly, shall be loaded
against the drum (see 4.9.1.3.1) and run continuously for 48 hours at 10 mph (16 km/h) and at
100 percent rated load capacity, as determined from table VIII for 10 mph (16 km/h). At the
conclusion of the test operation, the tire shall be examined externally and then internally, by
removal from the metal base and subsequent sectioning of the tire, to determine conformance
to 3.5.5.
