COATS 90C Leverless Air Center-Clamp Tire Machine
Coats 90C Leverless Center Clamp Tire Changer for High-Volume Car and Light Truck Service
The Coats 90C Leverless Center Clamp Tire Changer delivers classic swing-arm speed combined with the wheel protection of a center clamp and the ease of a fully leverless mount/demount system - the most complete combination of speed, safety, and wheel care available in the C-Series lineup. Handling rim diameters from 12" to 30" and tires up to 50" in diameter on wheels up to 15" wide, the 90C services the full range of passenger car and light truck applications. Available in an electric model (80090CEH220) with a 220V, 60 Hz, 14-amp, 2 HP motor and an air model (80090CAH3) powered by a 1.5 HP, 110-175 psi air motor, the 90C is built on the same heavy-duty chassis platform as the 80C with one critical upgrade: the standard-equipped Leverless Duckhead Mount/Demount Tool that eliminates tire bars from the process entirely. Backed by Coats' 3-year parts / 6-month labor warranty with a 5-year pro-rated transmission warranty, this machine is engineered for shops that refuse to compromise on wheel protection or throughput.
Coats 90C Leverless Center Clamp Tire Changer Features
Leverless Duckhead Mount/Demount Tool
The defining upgrade of the 90C over the 80C is the standard-equipped Leverless Duckhead Mount/Demount Tool - a powered tool head that mounts and demounts tires without traditional tire irons or bars. The leverless design acts as an additional helper device on top of the RoboRoller, mechanically lifting and guiding the tire bead over the rim flange without the metal-on-metal contact that traditional tools can cause. For shops servicing expensive custom alloy wheels or high-end performance fitments, this feature alone justifies the upgrade from the 80C, dramatically reducing the risk of costly wheel damage claims and tool-related marring.
Upgraded Bead Loosening System - Power In/Out and Freeze
The 90C's bead loosening system features Hand Control with Power In/Out and Freeze - a significant enhancement over the standard hand control system on the 80C. Power In/Out gives the technician motorized control of the bead loosener's travel direction from the point of use, while the Freeze function stops loosener movement instantly and holds position on demand. This level of precision control keeps the operator in direct line of sight with the tire during loosening, reducing the risk of bead loosener contact with the wheel rim and giving technicians confident, repeatable results on every wheel.
Center Locking Clamp Design
The 90C's center locking clamp uses the same proven two-moving-part mechanism found in the 80C - fast to operate, built to withstand high duty cycles, and designed to hold alloy and steel wheels securely without traditional rim clamp jaws contacting the wheel flange. The center clamp approach eliminates the primary source of rim scratching associated with conventional jaw-clamp machines, making the 90C an ideal choice for shops where alloy wheel damage complaints are a concern. The manual lock mechanism is intuitive for technicians already familiar with Coats swing-arm equipment.
RoboRoller Powered Assist
The RoboRoller is an air-powered, articulating roller arm that applies direct, controlled pressure on the tire bead during mounting, preventing the bead from riding back over the mount/demount tool head. Working in combination with the Leverless Duckhead, the RoboRoller effectively gives the 90C two powered helper devices operating simultaneously - a capability that makes light work of stiff-sidewall applications including run-flat tires, low-profile performance fitments, and large light truck tires that challenge single-helper machines.
Standard Auxiliary Bead Sealer (ABS)
The Auxiliary Bead Sealer is included as standard equipment at no additional cost. The ABS delivers a concentrated burst of air directly to the bead area of the assembly rather than relying solely on the tower volume, seating beads faster and more reliably - particularly on oversized light truck tires and tires with asymmetric bead profiles. The 5.4-gallon tower volume combined with the ABS gives technicians both on-demand high-volume air and precision-directed airflow for virtually any bead seating challenge they encounter.
Swing-Away Arm with 18" Robo-Arm Vertical Stroke
The mount/demount arm swings fully away from the turntable for unrestricted wheel loading and unloading, maintaining the fast ground-to-ground cycle times that Coats swing-arm machines are known for. The integrated Robo-Arm provides 18" of automated vertical stroke, guiding the Leverless Duckhead tool head through the full range of bead travel without manual repositioning. Dual gauges - inflation (0-60 psi) and air supply (0-300 psi) - are positioned for easy at-a-glance monitoring throughout the service cycle.
Coats 90C Leverless Center Clamp Tire Changer Applications
- High-Volume Retail Tire Shops Handling Premium Wheels: The 90C's leverless tool head and center clamp system work together to eliminate the two most common sources of wheel damage - tire iron contact and jaw clamp scratching - making it the right choice for shops where expensive alloy wheel damage claims are a recurring cost concern.
- Performance and Specialty Tire Shops: Shops focused on low-profile, ultra-high-performance, and run-flat fitments will benefit from the 90C's dual helper system (Leverless Duckhead plus RoboRoller), which provides the mechanical advantage needed to safely mount and demount tires that defeat standard single-helper machines.
- Dealership Service Departments: New-car dealers regularly encounter the full spectrum of OEM wheel and tire combinations, including run-flat equipped vehicles and large-diameter alloy factory wheels. The 90C's leverless design and center clamp system protect these assemblies while keeping service lane throughput high.
- Independent Full-Service Auto Repair Shops: For general repair shops that handle a broad mix of vehicles, the 90C's 12"-30" rim diameter range and leverless operation provide the versatility to service any passenger car or light truck fitment without requiring a specialized machine or exposing the shop to wheel damage liability.
- Fleet Maintenance Operations with Mixed Vehicle Types: Commercial and municipal fleet operations servicing vans, pickup trucks, and utility vehicles appreciate the 90C's robust chassis, center clamp reliability, and upgraded bead loosening system, which together minimize unplanned downtime and deliver consistent results across varying wheel and tire types.

Our equipment specialists can help with model selection, installation planning, and specifications for your shop.
Coats 90C Leverless Center Clamp Tire Changer FAQ
What makes the Coats 90C different from the Coats 80C?
The 90C and 80C share the same chassis platform, center clamp system, RoboRoller, ABS, footprint, and power configurations. The two key upgrades on the 90C are: (1) the standard Leverless Duckhead Mount/Demount Tool, which eliminates the need for a tire bar during mounting and demounting by mechanically lifting the bead over the rim flange without metal-on-metal tool contact; and (2) an upgraded bead loosening system with Hand Control - Power In/Out and Freeze, which gives the technician powered, directional control of the bead loosener from the point of use rather than a fixed hand control. These two differences make the 90C the better choice for shops handling premium alloy wheels or a high volume of difficult tire fitments.
What rim diameter range does the Coats 90C handle?
The Coats 90C handles external rim diameters from 12" to 30", covering the full range of passenger car and light truck wheels in standard use today. Maximum tire diameter is 50" and maximum rim width is 15". This range makes the 90C suitable for everything from compact car wheels to full-size light truck and SUV fitments, including modern oversized factory alloy wheels, without requiring adapters or machine reconfiguration for standard applications.
Does the leverless design really eliminate the need for a tire bar?
Yes. The Leverless Duckhead Mount/Demount Tool on the 90C is specifically engineered to remove the tire bar from the process entirely during standard passenger car and light truck tire service. The tool head mechanically hooks under and lifts the tire bead over the rim edge during demounting, and guides the bead over the flange during mounting, using the machine's powered vertical stroke rather than manual tire iron leverage. For the most extreme stiff-sidewall applications, Coats offers the optional Reverse Mount Adapter (PN 85612559) as a supplement. In normal day-to-day shop use, tire bars are not required.
What are the electrical requirements for the 90C electric model?
The electric model (80090CEH220) requires a dedicated 220V, 60 Hz, single-phase circuit rated for at least 14 amps, properly grounded and protected by an appropriately sized breaker. A licensed electrician should install and certify the circuit prior to machine installation. All electrical connections must be in place and ready before the installation technician arrives. The air model (80090CAH3) requires no electrical connection for the turntable drive - only a clean, dry air supply of 110-175 psi at 15 scfm is needed.
How much floor space does the Coats 90C require?
The Coats 90C has a machine footprint of 74" wide x 65" deep x 88" tall - identical to the 80C. In addition to the machine footprint, plan for adequate working clearance on all sides, particularly in front of the machine for swing-away arm travel and wheel handling. A minimum bay width of 12 feet is a practical planning guideline, though actual clearance needs will vary depending on your bay layout and the size of the tire and wheel assemblies you service most frequently.
What warranty does the Coats 90C carry?
The Coats 90C is covered by a 3-year parts warranty and a 6-month labor/on-site warranty, with a pro-rated 5-year transmission warranty (full coverage through year 3; 60% customer cost in year 4; 80% in year 5). Air-operated cylinder components, valves, seal kits, and hoses are covered for 1 year. Wear items including Leverless Duckhead plastic inserts, wheel protector boots, drive belts, and bead loosener pads are consumables excluded from coverage. The warranty is non-transferable, applies to the original end user, and requires clean, dry air to all air-operated components. Call 1-800-688-9240 for US warranty service.
What is included with the Coats 90C at time of purchase?
The Coats 90C ships ready for immediate use with: Auxiliary Bead Sealer (ABS), Bead Loosener Shoe Socks (2), Paste Lube Bracket and Brush, Protection Cones for Center Lock (2), Leverless Duckhead Mount/Demount Tool Plastic Inserts, Paste Lube, Anti-Rotation Extension Pin, Light Truck Cone (5.86" center bore), Rubber Protection Pads (2), and a Premium Storage Cabinet. Optional accessories including a Reverse Mount Adapter, Point-of-Use Lift System, Manual Drop Center Tool, and EL-X Express Lane Inflation System are available separately.
How does the Coats 90C handle run-flat tires?
The 90C is one of the strongest machines in its class for run-flat tire service. The combination of the Leverless Duckhead and the RoboRoller powered assist gives technicians two simultaneous powered helpers - the Duckhead mechanically guides the stiff run-flat bead over the rim flange without tire irons, while the RoboRoller holds the bead in the drop center and prevents rollback during mounting. For the most extreme run-flat and stiff-sidewall fitments, the optional Reverse Mount Adapter (PN 85612559) further expands the machine's capability.
How does the 90C ship and what does delivery look like?
The Coats 90C ships via LTL freight at a crated weight of 700 lb. Free freight shipping is included to commercial addresses in the 48 contiguous United States. Standard delivery is curbside - a forklift or loading dock is required to unload the machine at delivery. Liftgate service, inside delivery, and residential delivery are not included in standard freight and may be available for an additional fee. Inspect all packages carefully for damage before signing the Bill of Lading. Contact us for current lead times prior to ordering.
Is professional installation available for the Coats 90C?
Yes. Professional installation by a factory-trained Coats technician is available and is typically included when purchasing through authorized Coats distributors. The machine must be in its final position with all electrical or air connections fully in place and ready before the technician arrives. Professional installation is strongly recommended to ensure proper machine setup, initial calibration of the leverless Duckhead system, protection of your warranty coverage, and hands-on operator training. Contact us to confirm installation availability in your area.
What routine maintenance does the Coats 90C require?
Key consumables to inspect and replace on a regular schedule include: Leverless Duckhead plastic inserts (PN 89233409), wheel protector boots and booties, the turntable drive belt, grip max clamp inserts, and bead loosener pads. These are considered wear items and are not covered under warranty. For both models, all air-operated components require a clean, dry, uncontaminated air supply - use of an inline FRL (filter-regulator-lubricator) unit is strongly recommended. Lubricate all pivot points and linkages per the intervals specified in the 80C/90C Installation and Operation Manual, and inspect the bead loosener Power In/Out mechanism for proper travel and freeze function at each preventive maintenance interval.
Can the 90C be used with both alloy and steel wheels?
Yes. The Coats 90C is designed and rated for use with both alloy and steel wheels on car and light truck applications. The center clamp system with manual lock holds the wheel by the center bore rather than the rim flange, making it inherently safer for alloy wheel finishes than traditional jaw-clamp machines. The included Protection Cones for Center Lock (2) and Rubber Protection Pads (2) provide additional contact point protection when working with high-finish alloy wheels. The leverless Duckhead further reduces the risk of tool-to-rim contact during the mount/demount process, making the 90C particularly well-suited for premium alloy wheel service.
