Scope
Content
This SAE Recommended Practice describes a test method for determination of heavy truck (Class VI, VII, and VIII) 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.
This document is intended to be a general guideline for testing on an ideal machine, and modifications to the protocols recommended within are expected depending on the requirements of each customer. Due care is necessary when modifying protocols to ensure that the integrity of the data is maintained.
Rationale
Content
The purpose of this revision is to correct minor errors in the existing document and to bring the document up to date in light of developments between 2010 and 2017. The original document referenced an over-the-road test machine that has since been decommissioned and is no longer available. The document has also been updated to include a new class of hybrid testing machines which test a tire while moving it over a paved surface in a controlled environment.
SAE J2675 has been reaffirmed to comply with the SAE Five-Year Review policy.
