Description / Abstract:
1. Scope--This SAE Recommended Practice describes the determination of
tire pull force properties for an uninclined tire (SAE J670e) on a
laboratory flat surface tire force and moment machine. It is suitable
for accurately determining pull forces and residual aligning moments
for passenger and light-truck tires. These properties are important
determinants of vehicle trim (See section 2.1.2). They describe
steady-state, free-rolling pull effects ascribable to tires.
The test method described in this document is suitable for comparative
evaluation of tires for research and development purposes. The method
is also suitable for modeling when followed carefully.
