SAE J2848/1_202303

This SAE recommended practice defines the system and component functions, measurement metrics, testing methodologies for evaluating the functionality and performance of tire pressure systems, and recommended maintenance practices within the known operating environments.

This document is applicable to all axle and all wheel combinations for single unit powered vehicles exceeding 7257 kg (16 000 US lb) gross vehicle weight rating (GVWR), and multi-unit vehicle combinations, up to three (3) towed units, which use an SAE J560 connector for power and/or communication, or equivalent successor connector technology, or which use a suitable capacity wireless solution.

Examples of included single chassis vehicles would be – utility and delivery vans, tow trucks, rack trucks, buses, recreational vehicles, fuel trucks, trash trucks, dump trucks, cement trucks, and tractors. Examples of combination vehicles using an SAE J560 or successor connector would be – enclosed van trailers, liquid tanker, platform trailer, logger trailers, auto transit trailers, and their associated and compatible towing power units. For combination vehicles including two or more trailers, the dollies are also included. The included vehicles can be newly manufactured vehicles or existing vehicles.

These systems are recommended to address all tires in service as originally installed on a vehicle by the OEM and/or specialty vehicle manufacturer, including the vehicle mounted spares, and, for the aftermarket (including replacement or spare parts) are recommended (but optional) to address all tire/rim combinations installed after initial vehicle sale or in-use dates.

This document will focus on tire pressure systems of the monitoring type.
