A value-added option for INTRAAX® and VANTRAAX® trailer suspension systems, TIREMAAX helps fleets and owner operators in their efforts to minimize costly tire wear and improve productivity and fuel mileage. This patent-pending system uses the trailer air supply to maintain tire inflation up to a preset level. TIREMAAX detects low tire pressure and signals the operator to situations or circumstances requiring attention. It responds by directing air from the trailer air tank to one or more tires when the pressure dips below a preset level. TIREMAAX is available in two configurations: TIREMAAX® EC (Electronic Control) and TIREMAAX® CP (Constant Pressure), the difference is the control unit. TIREMAAX EC features an electronic control unit that provides full system programming and monitoring. TIREMAAX CP features a pneumatic pressure regulator and a simpler mechanical design.

TIREMAAX® EC

TIREMAAX EC controller

Comes preprogrammed in pressure settings from 70 to 130 psi in five-psi increments
An optional, hand-held programming tool allows target pressure reprogramming and access to status information
Checks tire pressure every 10 minutes
Indicator comes on when tire pressure is low by 20 psi or more
Supply and delivery ports take 1/8-inch NPT fittings and are on opposite sides of the controller
Non-pressurized seals and lines — when not inflating
Smart system (ECU controlled)
LED power indicator on ECU
Blink codes on ECU for troubleshooting

TIREMAAX® CP

TIREMAAX CP controller

Comes preprogrammed in pressure settings from 70 to 120 psi in five-psi increments
An integrated pressure control unit allows target pressure to be reset to any value other than the factory preset value
Checks tire pressure continuously without pressurizing the axle or wheel ends
Indicator comes on when system flow exceeds approximately 0.7 cfm
Supply port takes 1/4-inch NPT fitting, delivery port takes 1/8-inch NPT fitting, both are on the same side of the controller

TIREMAAX Configuration	Available TIREMAAX Target Pressure Settings (psi)
TIREMAAX EC¹	70, 75, 80, 85, 90, 95, 100, 105, 110, 115, 120, 125, 130
TIREMAAX CP²	70, 75, 80, 85, 90, 95, 100, 105, 110, 115, 120

1. Target pressure setting is factory programmed and selected by the customer to one of 13 possible target pressures. An optional hand-held programming device is available to program a target pressure other than the factory preset value.

2. Target pressure setting is factory programmed and selected by the customer to one of 11 possible target pressures. A standard, integrated pressure control unit allows target pressure to be easily reset to any value other than the factory preset value.
