The COATS® CHD-9551 Heavy Duty Tire Changer represents the absolute pinnacle of tire changing technology for high-volume commercial operations. Engineered specifically to conquer the most demanding tire service challenges, this premier model is the ultimate solution for shops that regularly work with super-single, skidder, agricultural, and off-road tires. When ordinary tire changers fall short, the CHD-9551 delivers the power, precision, and automation needed to handle even the toughest jobs with confidence and efficiency.
Designed for professional shops that demand both capability and productivity, the CHD-9551 combines a robust 4-jaw chuck system with advanced automation features that dramatically reduce service time and operator fatigue. Its full frame construction and powerful hydraulic components deliver the muscle required for wheels up to 3,300 lbs, while the innovative remote-controlled rotating tool head provides unmatched convenience and speed during tool changes.
The COATS® CHD-9551 stands apart as the top-of-the-line tire changer in the CHD series, purpose-built for shops that face the most challenging tire service work. This is the machine you turn to when handling massive construction equipment tires, agricultural machinery, or heavy-duty commercial vehicle applications. With its side-mounted moving table design and clamp arm lifting system, the CHD-9551 makes positioning and securing even the largest wheels straightforward and safe.
Whether you're servicing Budd & Dayton wheels, working with tube or tubeless configurations, or handling specialty applications, this machine adapts to your needs. The hook and roller mount/demount system on a reversible mount ensures clean, damage-free tire changes, while the permanently mounted automatic tool head offset maintains perfect positioning throughout the entire service process.
Capacity is where the CHD-9551 truly shines. This powerhouse handles tires up to 95 inches in diameter and 51 inches wide with ease, while the 4-jaw chuck accommodates rim diameters from 14 to 46 inches as standard—and up to 56 inches with optional clamping extensions. The massive 7,017 ft-lbs of maximum chuck torque combined with 10,802 lbs of clamping power ensures secure grip and confident operation even on the most stubborn tire and wheel combinations.
But raw power is only part of the story. The CHD-9551 offers the most automated features in the entire CHD line, significantly reducing the physical demands on operators and speeding up service times. The remote-controlled rotating tool head and arm allows for the fastest, easiest tool changes in the industry—operators can reconfigure the machine for different tire types without wrestling with heavy manual adjustments. An optional wireless remote takes this convenience even further, giving technicians complete freedom to move around the machine without being tethered by cumbersome cables.
Powered by a 208-230VAC, 3-phase, 60Hz electrical system drawing just 15 amps, the CHD-9551 delivers industrial-grade performance without requiring extraordinary power infrastructure. The 2.9 HP hydraulic motor drives the machine's lifting and positioning systems, while the 3.2-4.4 HP chuck rotation motor provides smooth, controlled rotation at speeds ranging from 5 to 11 RPM. This variable speed control allows operators to match rotation speed to tire type and service requirements for optimal results.
Despite its impressive power, the machine operates at an acoustic pressure level below 70 dBA, maintaining a more comfortable working environment for technicians who spend hours operating the equipment. The full frame structure measuring 112" wide by 81" deep by 75" high provides rock-solid stability, with a machine weight of 2,596 lbs ensuring the unit stays firmly planted even when handling its maximum wheel weight capacity of 3,300 lbs.
