Tire Pressure Systems - Maintenance (ATIS) Type For Medium and Heavy Duty Highway Vehicles
This SAE recommended practice defines the system and component functions, measurement metrics, testing methodologies for evaluating the functionality and performance of ground vehicle tire pressure maintenance systems (systems which automatically restore the inflation pressure to its specified level), and recommended maintenance practices for these systems within the known operating environments.
These systems are recommended to address all serviceable tires in service as originally installed on a vehicle by the OEM and/or specialty vehicle manufacturer, 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 is applicable to all axle and all wheel combinations for single unit powered vehicles exceeding 7257 kg (16,000 US lbs ) 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. For combination vehicles including two or more trailers, the dolly axles are also included. The included vehicles can be newly manufactured vehicles or existing vehicles.
Rationale: This document is complimentary to SAE J2848 - tire pressure monitoring systems. Both monitoring and maintenance systems are realities on the market, and recommended practices are needed for both cases. Since maintenance systems are distinctly different from monitoring it was necessary to dcoument them separately.
