Scope

1.1 This test method covers the static non-rolling laboratory method of determination of a tubeless tires resistance to bead unseating. The test requires the use of a standardized fixture and load machine. The test is conducted using a defined test pressure and method of determining the resultant force to unseat the tire from the rim.

1.2 This test method is applicable for all passenger, light truck, and temporary spare tires used on motor vehicles with 4536 kg (10 000 lb) Gross Vehicle Weight Rating (GVWR) or less.

1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Significance and Use

This test method establishes a standard procedure for the test and provides data that can be related to the force required to unseat the bead of a tire inflated with a specified pressure from the rim. This test method does not establish performance limits or tolerances for tire specifications.
