Choose the Coats Tire Changer Architecture First
Coats tire changers cover several different workflows. RC and MAXX machines use familiar rim-clamp architecture. The 80C and 90C move to center clamping, with the 90C adding a leverless Duckhead system. APX 90, APS 3000, and 9028E use tilt-back layouts, while the CHD series is built for heavy truck and commercial tire assemblies.
| Coats family |
Machine style |
Verified range or distinction |
Start here when |
| RC-45 / RC-55 |
Compact rim clamp |
6 to 24 in clamping range; RC-55 adds the Robo-Arm helper device |
Bay space is tight and the shop needs a straightforward passenger/light-truck tire machine |
| MAXX 50 / 70 / 80 / 90 |
High-use rim clamp |
Air and electric configurations are represented; compatible wheel-lift options are available across the family |
Daily tire volume, repeatable workflow, and technician handling matter |
| 80C / 90C |
Center clamp |
Both use center clamping and RoboRoller support; 90C adds a leverless mount/demount tool |
Wheel protection and controlled handling of difficult assemblies are priorities |
| APX 90 / APS 3000 / 9028E |
Tilt back |
APX 90: 9 to 30 in external; APS 3000: 12 to 34 in; 9028E: 10 to 28 in external |
The shop wants tilt-back access and a broader specialty or performance-tire workflow |
| CHD 6330 / 9041 / 9551 |
Heavy-duty truck |
13 to 27 in on CHD 6330; 14 to 46 in on CHD 9041 and CHD 9551 |
Truck, bus, agricultural, or other heavy wheel assemblies define the workload |
MAXX Tire Changers for High-Use Bays
Coats positions the MAXX family around repeated daily use and a consistent technician process. The current lineup includes MAXX 50, 70, 80, and 90 machines with air and electric configurations represented in the GSG catalog. Coats also offers compatible wheel-lift configurations that raise heavy assemblies to tabletop height rather than requiring the technician to lift them manually.
The model number should not be treated as a simple ranking. Compare the exact clamping, bead-handling, power, wheel-lift, and included-tool configuration for the machine being ordered.
RC-45 vs. RC-55
The RC family is the compact end of the current Coats tire changer lineup. Both RC-45 and RC-55 use a 35 by 44 inch footprint and a 6 to 24 inch clamping range. The important distinction is the assist system: RC-55 includes the Robo-Arm helper device for controlling the bead during difficult low-profile and run-flat work, while RC-45 is the simpler classic rim-clamp configuration.
Center Clamp and Leverless Tire Changers
The 80C and 90C hold the wheel through a center-clamp system instead of conventional tabletop jaws. Both use Coats bead-handling assistance, while the 90C adds a leverless Duckhead mount/demount tool. That changes the technician workflow and can reduce reliance on a tire bar when working close to the rim.
APS 3000 takes another center-lock approach within a tilt-back platform. Coats documents a 12 to 34 inch rim range, dynamic bead-loosening discs, and a leverless bead lifter. APX 90 and 9028E remain tilt-back machines but use different clamping and bead-loosening systems, so do not treat all three as one specification set.
Heavy-Duty Coats Tire Machines
Truck tire service requires a different machine class. Coats documents the CHD 6330 for rims from 13 to 27 inches, while CHD 9041 and CHD 9551 cover 14 to 46 inch rims. Maximum tire diameter and wheel weight also increase substantially across the CHD range, so choose the heavy-duty model from the actual fleet work rather than the rim diameter alone.
Do not use a passenger-car tire changer specification to qualify truck work. Rim diameter, tire diameter, tire width, wheel weight, power supply, and tooling all change when the job moves into heavy-duty tire service.
Parts and Complete Machines Are Mixed in the Current Collection
The live catalog membership includes complete tire changers, matched changer/balancer packages, and replacement components. A motor, Robo-Arm kit, clamp cylinder, Duckhead, or bead-breaker part is not a tire changer. Confirm the product type and model number before comparing specifications.
If you are maintaining an existing machine rather than buying a complete changer, use the Coats tire changer parts and accessories collection to narrow replacement-part searches by model and part number.
Coats Tire Changer FAQs
What is the difference between a Coats tire machine and tire changer?
In buyer searches, the terms usually describe the same equipment category. Coats uses tire changer as the product term for machines that mount and demount tires, while buyers often search for the same equipment as a Coats tire machine.
Which Coats tire changer is leverless?
The current lineup includes multiple leverless approaches. The 90C uses a leverless Duckhead on a center-clamp platform, APS 3000 includes a leverless bead lifter, and specific MAXX or APX configurations may add leverless tooling. Verify the exact model and part number rather than assuming an entire family is leverless.
What is the difference between Coats RC-45 and RC-55?
Both are compact rim-clamp tire changers with a 6 to 24 inch clamping range. The RC-55 adds the Robo-Arm helper device for pressing the bead into the drop center and helping with difficult low-profile or run-flat tires. RC-45 is the simpler configuration.
Does Coats make motorcycle tire changers?
Yes. The GSG assortment includes motorcycle-oriented Coats tire changer configurations and motorcycle clamps or tooling. Verify the exact rim and tire range of the selected machine before treating a passenger-car configuration as motorcycle-compatible.
Does Coats make truck tire changers?
Yes. Coats CHD heavy-duty tire changers are designed for substantially larger commercial wheel assemblies than passenger-car machines. The CHD 6330, 9041, and 9551 have different rim, tire, wheel-weight, and power ranges, so select by the actual fleet application.
How much does a Coats tire changer cost?
Pricing varies widely by machine architecture, tire range, assist systems, power configuration, and heavy-duty capability. Use the product grid for current pricing and compare the complete configuration rather than relying on a static collection-page price.
Match the Machine to the Tire Work
Start with the assemblies entering the bay, then compare clamping architecture, wheel and tire range, assist features, power, compressed air, and working clearance. If the bay also needs balancing equipment, compare Coats wheel balancers or Coats tire changer and wheel balancer combos.
