Product Code:SAE J2848/1
Title:Tire Pressure Monitoring Systems - For Medium and Heavy Duty Highway Vehicles
Issuing Committee:Truck And Bus Tire Pressure Management Systems Committee
Scope:This SAE recommended practice defines the system and component functions, measurement metrics, testingmethodologies for evaluating the functionality and performance of tire pressure systems, and recommended maintenancepractices 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, orwhich 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 combinationvehicles using an SAE J560 or successor connector would be – enclosed van trailers, liquid tanker, platform trailer, loggertrailers, auto transit trailers, and their associated and compatible towing power units. For combination vehicles includingtwo or more trailers, the dollies are also included. The included vehicles can be newly manufactured vehicles or existingvehicles.These systems are recommended to address all tires in service as originally installed on a vehicle by the OEM and/orspecialty vehicle manufacturer, including the vehicle mounted spares, and, for the aftermarket (including replacement orspare parts) are recommended (but optional) to address all tire/rim combinations installed after initial vehicle sale or inusedates.This document will focus on tire pressure systems of the monitoring type.NOTE: The following systems are not being addressed in this edition of the document. The management system typesand more mature/complex versions of maintenance and management types, to include on-boardreporting/storage/retrieval data capabilities for both, will be addressed separately by future changes/additions tothis document series.1] Tire Pressure Maintenance Systems – (typically known as ATIS – Automatic Tire Inflation Systems) systemswhich sense pressure directly or indirectly and maintain tire pressure above a minimum specified threshold, andinform the driver of the system’s activity.2] Tire Pressure Management (adjustment) Systems (typically known as CTIS – Central Tire Inflation Systems) –systems which sense pressure, plus other pertinent parameters (i.e., vehicle load and speed, tire temperature,etc.) directly or indirectly, and adjust or sustain the pressure at a the level appropriate for the conditions, andinform the driver of the system’s activity.
