ABOUT THIS MANUAL
This manual is provided to support Hendrickson

CP and TIREMAAX
®
PRO tire inflation
systems. The manual provides the following

• Troubleshooting
• Glossary
• Appendices
SYSTEM OVERVIEW
The Hendrickson TIREMAAX tire inflation system
is available in two versions: TIREMAAX CP and
TIREMAAX PRO. System highlights include:
• TIREMAAX PRO and CP controllers use trailer air
tank supply to provide a constant regulated target
pressure to air seals and hoses to inflate all tires.
• TIREMAAX PRO additionally monitors and deflates
tire pressure as needed
FEATURES
Features include:
• Indicator lamp (Figure 4 on page 12) that
illuminates when regulated air flow exceeds the
designed threshold. This occurs while tires are
inflating or there is a system leak.
• Tire pressure is continuously and automatically
held at target pressure for inflation.
• Does not pressurize axle tube (helps prevent
contamination of seals).
• In-axle filter prevents hub contamination and
allows any wheel-end air leaks to evacuate
through the axle vent.
• Seal and line leaks will not pressurize wheel ends.
• No venting at wheel end helps prevent
contamination from entering hubcap.
• Integrated valves isolate tires from system when
there is a problem (e.g. damaged or flat tire).
• The rotary union is incorporated in the hubcap
assembly for simpler installation and service.
• Manual pressure check or fill is available through
tire hoses at the hubcap.
• Inflates tires and detects leaks.
• Air supply valve includes a screen that prevents
debris from entering system and helps keep lines
and seals clean.
• Tire target pressure set to OE specifications.
• TIREMAAX PRO includes a deflation pressure that
is preset greater than the target pressure. Excess
pressure above the deflation pressure is exhausted.
