Meritor Tire Inflation System (MTIS) Overview
The Meritor Tire Inflation System (MTIS) is North America’s leading automatic tire inflation system‚ designed for wide compatibility across various axle and wheel-end combinations. It helps keep tires properly inflated‚ reducing wear and increasing fuel economy for trailers.
MTIS Benefits
Equipped on over 1 million trailers‚ the Meritor Tire Inflation System (MTIS) helps maintain optimal tire pressure. This leads to reduced tire wear‚ increased fuel economy‚ and improved overall operational efficiency for trailers.
Reduced Tire Wear
Maintaining proper tire inflation with the Meritor Tire Inflation System (MTIS) significantly contributes to reduced tire wear. When tires are consistently inflated to the correct pressure‚ the contact patch with the road is optimized‚ leading to even wear across the tire surface. Over- or under-inflated tires cause uneven wear patterns‚ shortening the tire’s lifespan and requiring more frequent replacements. By automatically maintaining the correct pressure‚ MTIS ensures that tires wear more evenly and last longer. This helps fleets reduce tire costs‚ minimize downtime‚ and improve overall operational efficiency. Proper inflation minimizes irregular wear‚ saving money.
Increased Fuel Economy
The Meritor Tire Inflation System (MTIS) plays a crucial role in enhancing fuel efficiency for trailers. Maintaining optimal tire pressure reduces rolling resistance‚ the force that opposes motion when a tire rolls on a surface. Under-inflated tires increase rolling resistance‚ requiring more energy (fuel) to propel the vehicle forward. By automatically regulating and maintaining proper tire inflation‚ MTIS minimizes rolling resistance‚ leading to significant fuel savings over time. These savings can be substantial for large fleets‚ contributing to a lower total cost of operation and a reduced environmental footprint. Consistent tire pressure ensures optimal performance and fuel efficiency.
MTIS Components
The Meritor Tire Inflation System comprises several key components‚ including a control box‚ stators‚ press plugs‚ and thru-tees. Each component plays a vital role in maintaining optimal tire pressure.
Control Box
The control box is a central component of the MTIS‚ often featuring a lid and sometimes a bracket for mounting. It regulates the air supply to maintain proper tire pressure. The control box integrates with the trailer’s existing air supply‚ monitoring and adjusting tire pressure automatically during vehicle operation. It ensures tires remain fully inflated‚ contributing to cost savings and improved bottom-line profitability. Furthermore‚ the control box may include service parts‚ as detailed in specific service publications‚ and should be inspected as part of regular MTIS maintenance. Its functionality is crucial for the overall efficiency of the system.
Stators
Stators are essential components within the Meritor Tire Inflation System (MTIS)‚ typically included in sets of four for tandem axle configurations. They play a critical role in the air distribution process‚ working in conjunction with other MTIS components to ensure proper tire inflation. When selecting an MTIS kit‚ it’s important to note whether the axle was prepped at the factory for MTIS‚ as this may affect the stators required. Stators contribute to the system’s ability to maintain consistent tire pressure‚ leading to reduced tire wear and increased fuel economy. Their proper functioning is vital for the overall effectiveness of the MTIS.
Press Plugs
Press plugs are crucial components of the Meritor Tire Inflation System (MTIS)‚ often supplied with adhesive and towelettes for proper installation. They are integral to sealing the wheel end and facilitating the transfer of air to the tire. When retrofitting an older trailer with MTIS‚ it’s essential to ensure the correct press plugs are selected for compatibility with the specific axle and wheel configuration. If the axle was MTIS-prepped at the factory‚ a kit without press plugs may be suitable. The press plugs are an important part of maintaining optimal tire inflation pressure‚ contributing to reduced tire wear‚ increased fuel economy‚ and overall system performance and longevity.
Thru-Tees
Thru-tees are vital components within the Meritor Tire Inflation System (MTIS)‚ facilitating air passage to maintain optimal tire pressure. These fittings are often equipped with flappers to prevent backflow and ensure consistent inflation. Dual wheel configurations typically utilize specialized thru-tees designed for their specific needs. Selecting the correct thru-tee‚ considering factors such as length and wheel setup‚ is crucial for proper MTIS functionality. Part numbers like 31317-03 designate specific thru-tee models suitable for particular applications. The thru-tees contribute significantly to the system’s ability to automatically inflate tires‚ leading to reduced wear‚ increased fuel economy‚ and enhanced overall performance of the vehicle.
MTIS Compatibility
The Meritor Tire Inflation System (MTIS) boasts compatibility with a broad spectrum of axle and wheel-end component combinations‚ solidifying its position as a versatile solution. It’s designed to work with major trailer axles and can often be retrofitted onto older trailer models. Ensuring compatibility requires careful consideration of factors like axle manufacturer and spindle style‚ whether straight or tapered. If the axle was prepped for MTIS at the factory‚ a specific MTIS Prepped Kit‚ excluding press plugs and stators‚ is used. Selecting the correct retrofit kit involves identifying wheel size and axle count‚ using compatibility charts to guide the decision-making process for optimal performance.
MTIS with ThermALERT
The Meritor Tire Inflation System (MTIS) with ThermALERT Standard is designed for compatibility and monitors wheel-end temperatures. If overheating occurs‚ the system activates‚ requiring repair or component replacement before returning to service.
Function of ThermALERT
The ThermALERT system‚ integrated with the Meritor Tire Inflation System (MTIS)‚ serves as a crucial safety feature by actively monitoring the temperature of wheel ends during vehicle operation. Its primary function is to detect any instances of overheating‚ which can indicate potential mechanical issues or component failures within the wheel assembly. When the ThermALERT system identifies an elevated temperature exceeding a predetermined threshold‚ it triggers an alert mechanism. This alert signals the need for immediate inspection and maintenance to prevent further damage or potential safety hazards. Addressing the cause of the overheating is essential before returning the vehicle to service‚ ensuring safe operation.
Finding the Correct MTIS Kit
To select the correct MTIS retrofit kit‚ identify the axle manufacturer and spindle style (straight or tapered). Then‚ determine the wheel size and the axle count for proper component selection.
Axle Manufacturer and Spindle Style
Identifying the axle manufacturer and spindle style is a critical first step in selecting the correct MTIS kit. The spindle can be either straight or tapered‚ each requiring specific components for proper installation and functionality. If the axle was prepped for MTIS at the factory‚ utilize the MTIS Prepped Kit‚ which typically excludes press plugs and stators. This simplifies the installation process and ensures compatibility with the existing axle configuration. Accurate identification of these factors guarantees a seamless integration of the MTIS‚ optimizing its performance and extending the lifespan of your tires.
Wheel Size and Axle Count
After determining the axle manufacturer and spindle type‚ specifying the wheel size and axle count is crucial for choosing the appropriate MTIS retrofit kit. Different wheel sizes require specific components to ensure proper fitment and optimal tire inflation. Furthermore‚ the number of axles on the trailer directly impacts the quantity of parts needed for a complete MTIS installation. Consult the provided charts to select the correct retrofit kit based on your trailer’s wheel size and axle configuration. Accurate selection guarantees the MTIS functions effectively‚ contributing to reduced tire wear‚ improved fuel economy‚ and enhanced overall safety.
MTIS Part Numbers
Specific MTIS components are identified by unique part numbers‚ such as H2200-02 and P778989. These numbers are essential for ordering replacements or when identifying parts in service publications.
