Designed specifically for heavy-duty trucks, tractors, and off-the-road (OTR) vehicles, this powerhouse tire changer features a 14-44 inch rim clamping range (expandable to 56 inches with optional extensions) and handles tires up to 43 inches wide. The integrated mobile control unit allows a single technician to safely operate all functions remotely, while the hydraulic non-return valve ensures the chuck maintains constant pressure to prevent rim slippage.

Hofmann Monty 4400 Features
Mobile Control Unit for Single-Technician Operation
The wired remote control console enables a single technician to safely oversee and operate all tire changing functions from a distance. This mobile control unit significantly improves safety by allowing the operator to maintain optimal viewing angles and safe positioning throughout the service process, while simultaneously boosting productivity by eliminating the need for multiple technicians on large commercial tire jobs.
Hydraulic Non-Return Valve System
The chuck is equipped with a sophisticated non-return valve that maintains constant hydraulic pressure, preventing the rim from slipping during tire changing operations. This critical safety feature ensures that even in the event of a sudden drop in hydraulic pressure, the chuck remains securely clamped, protecting both the operator and the expensive wheel assembly from damage. The system provides reliable, consistent clamping force throughout the entire tire service procedure.
Advanced Tilting Bead Breaker System
The bead breaker disk features a special tilting mechanism that automatically adjusts to optimize breaking force and maintain the ideal position relative to the rim profile. This intelligent design maximizes bead breaking efficiency on stubborn commercial tires while minimizing the risk of rim damage. The tilting system adapts to various wheel geometries and tire conditions, ensuring consistent results across different vehicle types and tire sizes.
Heavy-Duty Capacity for Commercial Applications
Built to handle the largest commercial vehicle wheels, the Monty 4400 accommodates wheel assemblies up to 90.5 inches in diameter and 3,300 lb in weight. The robust rim clamping system securely grips rims from 14 to 44 inches in diameter, with optional extensions available to expand capacity to 56 inches. This exceptional range makes the Monty 4400 suitable for everything from medium-duty trucks to large OTR equipment.
Wide Tire Handling Capability
The Monty 4400 is engineered to service tires up to 43 inches wide, accommodating the full spectrum of commercial tire profiles from highway truck tires to wide-base singles and agricultural equipment tires. The generous working width ensures technicians can efficiently service modern super-single tires and other wide commercial tire designs without interference or limitations.

Hofmann Monty 4400 FAQ
What is the maximum wheel size the Monty 4400 can handle?
The Hofmann Monty 4400 can accommodate wheel assemblies up to 90.5 inches in diameter and 3,300 lb in weight. The rim clamping range is 14-44 inches as standard, which can be expanded to 56 inches with optional extensions. Maximum tire width capacity is 43 inches. This makes it suitable for heavy-duty trucks, tractors, buses, and most OTR equipment. If you're servicing particularly large mining or industrial equipment, contact us to confirm compatibility with your specific wheel sizes.
Can one technician operate this tire changer safely?
Yes, the Monty 4400 is specifically designed for safe single-technician operation through its mobile wired remote control unit. The operator can control all tire changing functions from a safe distance, maintaining optimal viewing angles and positioning throughout the service process. The non-return valve system provides additional safety by preventing rim slippage even if hydraulic pressure drops unexpectedly. However, when servicing the largest and heaviest wheel assemblies, having an additional technician to assist with positioning and handling is recommended for efficiency and safety.
What electrical service is required for installation?
The Hofmann Monty 4400 requires 208V 3-phase 60Hz electrical service. A licensed electrician must install a dedicated circuit with appropriate wire gauge and overcurrent protection based on local electrical codes and the machine's specifications. Verify that your facility has 3-phase power available before ordering, as single-phase power is not compatible. Installing incorrect voltage or using an undersized circuit will damage the equipment and void the warranty. Professional electrical installation is strongly recommended and may be required for warranty coverage.
Does the Monty 4400 require special foundation or anchoring?
Yes, the Monty 4400 must be properly anchored to a reinforced concrete floor for safe operation. The floor must be minimum 6 inches thick with compressive strength of at least 3,000 PSI. The floor must be level within 1/4 inch across the machine footprint. Use only the anchor bolts and installation procedures specified in the installation manual. Proper anchoring is critical for operator safety and is required to maintain warranty coverage. Professional installation is strongly recommended to ensure correct anchoring and equipment setup.
What warranty coverage does Hofmann provide?
Hofmann provides comprehensive limited warranty coverage on the Monty 4400, protecting against defects in materials and workmanship under normal use. Complete warranty terms, coverage periods, and conditions are detailed in the warranty documentation included with your equipment. Warranty coverage requires proper equipment registration, professional installation per manufacturer specifications, regular maintenance per the service schedule, and operation within rated capacity. The warranty does not cover damage from improper use, lack of maintenance, unauthorized modifications, or normal wear items. Review the complete warranty documentation for full terms and exclusions.
What comes included with the Monty 4400?
The Monty 4400 includes the main tire changer unit, mobile wired remote control unit, hydraulic non-return valve system, tilting bead breaker assembly, and standard rim clamping jaws covering the 14-44 inch range.

Professional installation services can help assess your facility and optimize equipment placement.
Can the Monty 4400 handle agricultural tractor tires?
Yes, the Monty 4400 is well-suited for agricultural tire service. The 14-44 inch rim clamping range (expandable to 56 inches) covers most agricultural tractor and implement wheel sizes. The 43-inch maximum tire width accommodates wide agricultural tire profiles, while the 90.5-inch maximum diameter and 3,300 lb weight capacity handle large tractor assemblies.
