Coats 800MAXX50A Air Rim Clamp Tire Changer for Car and Light Truck Service
The Coats 800MAXX50A is the air motor variant of the professional-grade Maxx 50 rim clamp tire changer, purpose-built for shops that run off compressed air and prefer to eliminate a dedicated 110V motor circuit from the equation. It handles rim diameters from 6" to 24", tires up to 50" in diameter, and wheels up to 16" wide - powered entirely by your shop's compressed air supply at 110-175 PSI, 15 SCFM, with the air drive system capable of up to 4 HP depending on supply pressure. Like all Maxx 50 machines, it's built on a chassis tested to 250,000 bead breaking cycles and ships ready to work at 750 lbs. Backed by Coats' 3-year parts warranty with 5-year prorated transmission coverage, the 800MAXX50A delivers the full Maxx 50 feature set without requiring a separate electrical circuit.
Coats 800MAXX50A Features
Air Motor Drive - No Electrical Circuit Required
The 800MAXX50A eliminates the need for a dedicated 110V motor outlet by running the drive system entirely off compressed air. The air motor is capable of up to 4 HP output depending on available shop air pressure, making this model well suited to shops where electrical capacity is limited, outlets are inconveniently located, or additional circuit installation would be costly. All other features of the Maxx 50 platform remain identical to the electric model.
Durable and Reliable Chassis
The 800MAXX50A shares the same wider, more robust chassis as the full Maxx 50 line - engineered to clamp extreme assemblies and tested to 250,000 bead breaking cycles for long-term durability in the harshest shop environments. The heavy-duty construction provides a stable, low-center-of-gravity platform that handles the full range of passenger car and light truck fitments without flex or fatigue.
Dual Nozzle Bead Sealer
A high-pressure dual nozzle inflation system with 5.4 gallons of air volume in the tower delivers substantially more airflow than single-point systems. This extra volume is particularly effective on stiff low-profile and run-flat tire beads that are slow to seat, reducing the number of inflation attempts needed and keeping floor-to-floor times down across a busy day of tire service.
No-Index Tabletop
The no-index tabletop design lets technicians skip the repositioning step that many competitor machines require when working on large assemblies. Fewer pedal presses and less repositioning time mean techs can move faster through oversized truck and SUV wheel fitments - a cumulative productivity gain that adds up over a full day of volume service.
Polymer Duckhead Mount/Demount System
The swing-away arm with nylon polymer duckhead mounts and demounts tires without contacting or scratching alloy and chrome wheel finishes. For shops servicing OE passenger and light truck vehicles, this protection against cosmetic wheel damage is essential. The duckhead is a field-replaceable wear item available directly from Coats (PN 8183061).
Field-Upgradable Platform
The 800MAXX50A is designed to grow alongside your business. The Robo-Arm helper device (PN 85009937) assists with difficult mounting and demounting, the Robo-Roller bead depressor arm (PN 85611867-01) keeps tough beads in the drop center, and a foot-operated bead loosener kit (PN 85611558-01) upgrades hand control to foot pedal operation. An optional factory-installed Maxx Wheel Lift is available on the 800MAXX50AL model, supporting assemblies up to 150 lbs at 150 PSI via foot pedal.
Coats 800MAXX50A Applications
- Shops with Limited Electrical Capacity: The air motor drive eliminates the need for a dedicated 110V circuit, making the 800MAXX50A the practical choice for shops where adding electrical outlets would require panel upgrades or costly electrician work.
- Independent Tire Shops: The no-index tabletop, dual nozzle bead sealer, and fast cycle times support high-volume passenger car and light truck throughput in busy independent tire operations.
- OE Dealership Service Bays: With 6" to 24" rim diameter coverage and a polymer duckhead that protects alloy finishes, the 800MAXX50A handles the full range of OE passenger and light truck fitments without risk of cosmetic wheel damage.
- Light Truck and SUV Specialists: The 50" maximum tire diameter, 16" maximum rim width, and 22"-wide bead loosener cover the larger wheel and tire assemblies common on pickup trucks, full-size SUVs, and crossovers.
- Shops Upgrading from Older Air-Operated Machines: For shops already running air-powered tire changers, the 800MAXX50A is a direct upgrade path - same power infrastructure, significantly more capability and platform longevity.

Coats 800MAXX50A Installation Requirements
Air Supply Requirements
Pressure: 110-175 PSI shop air required. Flow: 15 SCFM minimum to adequately support the air motor drive, dual nozzle inflation system, and air-operated clamping cylinders simultaneously. The 800MAXX50A does not require a dedicated 110V electrical outlet - the drive system runs entirely off the compressed air supply. Coats specifies that air-operated components must be supplied with clean, dry air; failures caused by water, rust, or foreign debris are not covered under warranty.
No Electrical Circuit Required
Unlike the electric model (800MAXX50E), the 800MAXX50A does not require a 110V motor circuit. A standard electrical outlet nearby may still be useful for lighting or accessory charging, but no dedicated machine circuit is needed. This makes placement flexible in bays where running new electrical wiring would be impractical or cost-prohibitive.
Space Requirements
Footprint: 74" wide x 44" deep x 81" tall. Plan for adequate clearance on all sides of the machine for safe operation, technician movement, and the full arc of the swing-away arm during mounting and demounting. The machine ships at 750 lbs and requires a forklift or pallet jack for placement.

Coats 800MAXX50A FAQ
What rim sizes does the Coats 800MAXX50A handle?
The 800MAXX50A handles external rim diameters from 6" to 24" with the standard steel clamp set. With the optional Grip-Max 30" Extended Clamps (PN 85607986, set of 4), the clamping range extends to 30". Maximum rim width is 16" and maximum tire diameter is 50", covering the full range of passenger car, light truck, and SUV fitments.
Does the Coats 800MAXX50A require any electrical hookup?
No - the 800MAXX50A is fully air-operated and does not require a dedicated 110V motor circuit. The drive system runs entirely off your shop's compressed air supply at 110-175 PSI, 15 SCFM minimum. This makes it a practical choice for shops with limited electrical capacity or bays where running a new circuit would be costly. A general-purpose outlet nearby may still be useful for accessories, but no machine-specific electrical work is needed.
What air supply does the Coats 800MAXX50A require?
The 800MAXX50A requires a shop air supply of 110-175 PSI at a minimum of 15 SCFM. This flow rate supports the air motor drive, the air cylinder-operated clamping system, and the dual nozzle bead inflation system simultaneously. The air motor output scales with available pressure - maximum output is up to 4 HP at higher supply pressures. Coats requires that air supply to the machine be clean and dry; contamination from water, rust, or debris voids coverage on air-operated components under warranty.
What is the footprint of the Coats 800MAXX50A?
The 800MAXX50A has a footprint of 74" wide x 44" deep x 81" tall. When planning your bay layout, account for additional clearance on all sides for safe technician movement and the full arc of the swing-away arm during mounting and demounting operations. The machine ships at 750 lbs and requires a forklift or pallet jack for positioning.
What is the Coats 800MAXX50A warranty?
The 800MAXX50A is covered by Coats' Maxx Series limited warranty: 3 years on parts, 6 months on labor and on-site charges, 1 year on air-operated components (cylinders, valves, seal kits, hoses - which on this model includes the drive motor), and 5 years on the transmission (prorated after year 3). The warranty applies to the original purchasing end user only and is non-transferable. Failures caused by air supply contamination are excluded. For warranty service, call 1-800-688-9240.
What accessories are included with the Coats 800MAXX50A?
The standard 800MAXX50A includes the machine with air motor drive, the 4-clamp air cylinder-operated clamping system (steel clamps, 6"-24" range), swing-away arm with nylon polymer duckhead, hand-operated bead loosening shovel (up to 22" wide), high-pressure dual nozzle inflation system, and paste lube bracket with brush. Optional accessories - including the Robo-Arm, Robo-Roller, foot pedal bead loosener, and extended clamp sets - are sold separately and installed by a Coats service representative.
How does the Coats 800MAXX50A ship, and what do I need for delivery?
The 800MAXX50A ships via LTL freight carrier at 750 lbs on a pallet. Freight shipping is free to commercial addresses in the 48 contiguous United States. A forklift or loading dock is required to unload the machine - curbside delivery is standard and the carrier will not move the machine into your shop. Inspect all packaging for damage before signing the Bill of Lading and note any visible damage on the delivery receipt prior to the driver departing.
Can I add a Robo-Arm or Robo-Roller to the Coats 800MAXX50A later?
Yes - the 800MAXX50A is built on the same field-upgradable Maxx 50 platform as the electric model. The Robo-Arm Helper Device Kit (PN 85009937) assists with mounting and demounting without rim damage. The Robo-Roller Bead Roller Arm Kit (PN 85611867-01) keeps tough beads in the drop center during mounting. A foot-operated bead loosener kit (PN 85611558-01) is also available. All add-ons are installed by a Coats service representative - contact your rep for pricing and scheduling.
What is the difference between the Coats 800MAXX50A and the 800MAXX50E?
The 800MAXX50A and 800MAXX50E are the same Maxx 50 machine with different power sources. The 800MAXX50A uses an air motor drive and requires no electrical circuit - it runs entirely off shop compressed air at 110-175 PSI. The 800MAXX50E uses a 110V electric motor. All tire changing features, clamping capacity, bead sealing, and upgrade options are identical between the two models. The choice comes down to your shop's available infrastructure: if adding a 110V circuit is inconvenient or costly, the 800MAXX50A is the better fit. Both models are available with an optional factory-installed wheel lift.
What kind of shops is the Coats 800MAXX50A designed for?
The 800MAXX50A is designed for shops that prefer or require an air-powered tire changer - including shops with limited electrical panel capacity, facilities where running new circuits is impractical, or operations already standardized on air-powered equipment. It handles passenger cars, light trucks, and SUVs (6"-24" rims, up to 50" tire diameter) and is not designed for commercial truck or heavy-duty applications. Coats' CHD and HIT series address those heavier segments.
What maintenance does the Coats 800MAXX50A require?
Regular maintenance includes lubricating the mount/demount arm and clamping components per the operation manual schedule, inspecting and replacing wear items such as the polymer duckhead, grip-max clamp inserts, and bead loosener pads as needed, and - critically for the air model - ensuring the compressed air supply is clean and dry at all times. An inline air dryer or filter-regulator-lubricator (FRL) unit is strongly recommended to protect the air motor and all air-operated components. Water or debris contamination voids warranty coverage on air components. Contact Coats at (615) 392-3193 to schedule preventative maintenance service.
Does the Coats 800MAXX50A handle low-profile and run-flat tires?
Yes - the 800MAXX50A is well equipped for low-profile and run-flat fitments. The dual nozzle bead sealer with 5.4-gallon tower volume provides the high-volume airflow needed to seat stiff low-profile beads reliably. The optional Robo-Arm and Robo-Roller add-ons provide additional leverage and bead control for the most challenging run-flat and reinforced sidewall tires, making the 800MAXX50A more capable with difficult fitments than most air-powered machines in its class.
