Scope:

This SAE Recommended Practice describes a test method for determination of heavy truck tire force and moment properties under combined cornering and braking conditions. The properties are acquired as functions of slip angle, normal force, and slip ratio. Slip angle and normal force are changed incrementally using a sequence specified in this document. At each increment, the slip ratio is continually changed by application of a braking torque ramp. The data are suitable for use in vehicle dynamics modeling, comparative evaluations for research and development purposes, and manufacturing quality control.

Rationale:

The original document made some assumptions with regard to future work that have not been met. Additionally, the overthe- road test machine mentioned in the text has been decommissioned and is no longer available. Additionally, other errors were found during the renewal examination. The purpose of this revision is to correct the known errors and bring the document up to date in light of developments between 2004 and 2010.
