With patented Robo-Arm technology, dual nozzle inflation system, and no-index tabletop design, the MAXX 90 Air combines power, efficiency, and reliability for high-volume tire service. Backed by a 3-year parts warranty and engineered for up to 250,000 bead breaking cycles, this tire changer is built for the demands of professional automotive service.
Coats MAXX 90 Air Features
Patented Leverless Tool Heads
The Coats MAXX 90 features a patented Leverless Bead Lifter, Robo-Roller, and Robo-Arm tool heads that mount and demount tires without traditional tire bars. This patented design eliminates potential wheel surface damage while making the changing process faster and easier for technicians. The leverless system works with passenger cars, light trucks, and extreme custom applications without requiring adjustments.
Pneumatic Power System
The air motor delivers up to 4 HP at shop pressures of 110-175 psi with 15 scfm air consumption, making it ideal for shops with existing compressed air infrastructure. This system is cost-effective to operate and provides consistent power for both standard and difficult tire assemblies. The pneumatic drive eliminates electrical installation requirements and integrates seamlessly with shop air systems.
Dual-Mode Bead Loosening Control
Choose between hand shovel or foot pedal control for bead loosening, allowing each technician to work their way. This flexibility accommodates different work styles and preferences, reducing fatigue and improving efficiency. The bead loosener operates on assemblies up to 22 inches wide, exceeding industry standards.
No-Index Tabletop Design
The no-index tabletop eliminates the need to reposition the assembly between operations, reducing the number of pedal presses and keeping technicians moving faster. This feature saves significant time on large, difficult wheel assemblies and improves workflow efficiency in high-volume operations.
Dual Nozzle Bead Sealing System
The dual nozzle inflation system delivers 5.4 gallons of air from the integrated tower, providing ample volume for seating difficult assemblies quickly. Double-point inflation ensures faster bead seating and seal integrity on low-profile and run-flat tires, reducing operator effort and cycle time.
GripMax 2.0 Extended Clamps
Four air-cylinder operated clamps with GripMax 2.0 extended system accommodate wheels up to 16 inches wide and securely grip alloy, steel, and light-to-medium truck wheels. The robust clamping system is tested for up to 250,000 bead breaking cycles, ensuring lasting reliability in demanding shop environments.

Coats MAXX 90 Air Installation Requirements
Compressed Air Requirements
Air Supply: 110-175 psi working pressure with 15 scfm consumption. The MAXX 90 Air requires connection to a shop compressor system capable of maintaining consistent pressure and volume during operation. Most shops with existing tire service equipment have adequate capacity, but verify your compressor output before ordering. Air Line: Use 3/4-inch or larger compressed air lines with appropriate quick-disconnect fittings for reliable connection.
Floor Space and Clearance
Equipment Footprint: 74 inches wide x 86 inches high x 44 inches deep. Allow minimum 36 inches of clearance on all sides for safe operation, maintenance access, and tire handling. The unit has a low center of gravity for stability and does not require floor anchoring in standard installations, though anchoring is recommended in high-traffic areas.
Shop Infrastructure
Air Quality: Ensure your compressor system includes adequate filtration and desiccant drying to prevent moisture and contaminants from entering the pneumatic motor. Drainage: Position the unit where condensation from air lines and operational fluids can drain safely. Lighting: Ensure adequate overhead lighting for safe tire work and wheel inspection.
Professional Installation
Coats includes free setup and training with equipment purchase.

Questions About the Coats MAXX 90 Air?
Our equipment specialists can help with compressed air requirements, installation planning, specifications, and product selection for your shop.
Coats MAXX 90 Air FAQ
What compressed air pressure does the MAXX 90 Air require?
The MAXX 90 Air motor operates at 110-175 psi with 15 scfm consumption. Most shops with existing tire service equipment have adequate compressor capacity. Verify your shop air pressure and volume before ordering. Higher pressure within the operating range provides increased motor speed and power output.
Can I use the MAXX 90 Air if my compressor is shared with other equipment?
Yes, the MAXX 90 Air can share a compressor system with other pneumatic equipment. At 15 scfm consumption, it integrates with most shop air systems designed for multiple tools. However, ensure your compressor can maintain 110-175 psi during simultaneous operation of multiple devices. Consult your compressor capacity before installation.
How does the air motor performance compare to the electric version?
The air motor delivers up to 4 HP at shop pressures (110-175 psi) with motor speeds of 7, 17, and 7 RPM. The electric version uses a 220V 2-speed motor with 4.0 HP at speeds of 10, 22, and 10 RPM. Both provide equivalent performance for tire changing; choose based on your shop's infrastructure (existing air vs. available electrical).
What installation is required for the air motor version?
Connect the MAXX 90 Air to your shop's compressed air system using 3/4-inch or larger air lines with appropriate quick-disconnect fittings. Ensure adequate air filtration and drying to prevent moisture contamination. No electrical work is required. Coats provides free installation and training with each purchase.
Does the MAXX 90 Air handle ultra-low-profile and run-flat tires?
Yes. The patented leverless tool heads, dual nozzle bead sealing system, and Robo-Arm technology are specifically designed to handle ultra-low-profile, run-flat, and other difficult assemblies. The no-index tabletop reduces operations needed, making difficult tire changes faster and easier.
What warranty does the MAXX 90 Air include?
The MAXX 90 Air includes a 3-year parts warranty, 6-month labor warranty, and lifetime structural frame warranty. Warranty covers defects in materials and workmanship under normal use conditions. Professional installation is required for warranty coverage. Coats provides free preventative maintenance and technical support for registered units.
How much space does the MAXX 90 Air require in the shop?
The MAXX 90 Air has a footprint of 74 inches wide x 86 inches high x 44 inches deep. Allow minimum 36 inches of clearance on all sides for safe operation, maintenance, and tire handling. Confirm adequate floor space and air line access before ordering. The unit does not require floor anchoring in standard installations.
What is included with the MAXX 90 Air purchase?
The MAXX 90 Air includes the tire changer unit with air motor, patented leverless tool heads, steel and high-spoke Duckhead tools, four GripMax 2.0 clamps, bead loosener socks, paste lube bracket, lift tool socks, complete documentation, free setup and training, and warranty documentation.
How does the no-index tabletop improve efficiency?
The no-index tabletop eliminates repositioning the wheel assembly between mount and demount operations. Technicians can complete more of the tire change without moving the wheel, reducing pedal presses and keeping them working faster. This feature particularly benefits high-volume operations and large, difficult assemblies.
What maintenance does the pneumatic motor require?
Pneumatic motors require basic maintenance including regular air filter changes, desiccant drying cartridge replacement, and occasional lubrication. Coats provides preventative maintenance guidance in the manual and through technical support. Most maintenance tasks are simple and can be performed in-house by shop technicians.
Does the air version have the same patented tool heads as the electric version?
Yes. Both the air and electric versions use the same patented leverless tool head system, Robo-Arm, Robo-Roller, dual nozzle inflation, and no-index tabletop. The only difference is the power source - pneumatic vs. electric motor. All other features and capabilities are identical.
What is the difference between 110-175 psi operating range?
The MAXX 90 Air motor operates effectively anywhere within the 110-175 psi range. Higher pressure toward 175 psi provides increased motor speed and power, while lower pressure around 110 psi still provides adequate performance. Most shops operate their air systems at 120-140 psi, which provides optimal balance of speed and efficiency.
