Hofmann Monty 8700 SmartSpeed Center-Post Leverless Tire Changer

The Monty 8700 accommodates rim diameters up to 15 inches (38 cm), tire widths up to 13 inches (33 cm), and maximum wheel diameters up to 47 inches (119 cm). This capacity range covers the vast majority of passenger vehicle tires, from compact cars through full-size SUVs and light trucks. The manual center-post clamp and leverless PowerMont system work effectively across this entire size range without requiring different tooling or adapters.

SmartSpeed is a patent-protected system that automatically analyzes each wheel's characteristics and establishes the optimal combination of motor torque and rotational speed. Rather than running at a fixed speed regardless of tire type, SmartSpeed adjusts in real-time to match the specific requirements of each tire, whether it's a stiff-sidewall run-flat or a standard passenger tire. This intelligent adjustment reduces the risk of tire or wheel damage while maximizing efficiency and eliminating the need for manual speed adjustments between different tire types.

The Hofmann Monty 8700 requires 230V single-phase 60Hz electrical service with a dedicated circuit breaker. This electrical supply must be installed by a licensed electrician and meet all local and national electrical codes. Unlike three-phase equipment that may require electrical service upgrades in some facilities, the single-phase requirement makes the Monty 8700 compatible with standard commercial electrical infrastructure found in most automotive service facilities.

Leverless tire changers like the Monty 8700 eliminate the metal tire irons used in traditional tire changing, which significantly reduces the risk of scratching, gouging, or damaging wheels during mount and demount operations. This is particularly important when servicing expensive custom wheels, chrome finishes, painted surfaces, or high-value OEM wheels where even minor cosmetic damage creates customer dissatisfaction and potential liability. The PowerMont system accomplishes the same tire mounting and demounting functions without metal-on-metal contact that causes most wheel damage in traditional tire changing operations.

The Monty 8700 requires a compressed air supply capable of delivering 116-174 PSI (8-12 bar) continuously to operate the pneumatic wheel lift, bead pusher, and bead seater. Your shop's air compressor system must maintain this pressure range during operation, which means the compressor must have sufficient capacity to supply both the tire changer and other pneumatic tools simultaneously. Install a dedicated air line with appropriate filtration and moisture separation to prevent water contamination and debris from damaging the tire changer's pneumatic components.

The Monty 8700 ships complete with the tire changer base unit, PowerMont leverless tool, dynamic dual-disk bead breaker with adjustable tilt mechanism, pneumatic wheel lift system, pneumatic bead pusher with reverse hook, top-side bead seater, color-coded control panel, installation hardware, anchor bolts, and complete documentation including owner's manual and installation guide. Optional accessories such as additional protection kits, rim clamp adapters, and specialty tools are available separately through the Hofmann accessory catalog.

The Monty 8700 ships via freight carrier on a pallet and requires either a forklift or loading dock for safe unloading. Standard curbside delivery means the freight driver will unload the pallet to ground level at the delivery location, but cannot move it into your facility or position it for installation. The substantial weight and dimensions of the tire changer make manual unloading unsafe and impractical. Arrange for appropriate material handling equipment to be available at your facility on the scheduled delivery day, and inspect all packaging for shipping damage before signing the bill of lading.

The manual center-post clamp design grips wheels from the center hub area rather than the outer rim edge like turntable designs, which significantly reduces contact with decorative wheel surfaces and minimizes clamping force required. This design eliminates contact with wheel faces, spokes, and painted or chrome surfaces where turntable jaws would typically grip. The center-post approach provides better access to the rim edge during tire removal and installation while reducing constraints that can damage wheels with unusual spoke patterns, deep dish designs, or decorative surface treatments.

Yes, the Monty 8700 is specifically engineered for run-flat (RFT) and ultra-high-performance (UHP) low-profile tires. The dynamic dual-disk bead breaker includes an adjustable tilt feature designed for the stiff sidewalls characteristic of run-flat tires, while the leverless PowerMont system eliminates the excessive force and wheel contact that traditional tire irons require when working with these challenging tire types. The SmartSpeed technology automatically adjusts torque and speed for the increased resistance of run-flat construction, making these difficult tire changes safer and more efficient while protecting expensive wheels.

Hofmann provides comprehensive limited warranty coverage protecting against defects in materials and workmanship under normal commercial use. Warranty terms vary by component and application, with specific coverage details provided in the Hofmann warranty documentation included with your tire changer. Warranty activation requires equipment registration within 30 days of installation and compliance with installation requirements including professional setup, proper electrical and air supply, and adherence to the manufacturer's maintenance schedule. Warranty service is performed by authorized Hofmann service centers using genuine replacement parts.

The pedal-operated pneumatic wheel lift uses compressed air power to raise and lower wheels up to 154 pounds, eliminating the need for technicians to manually lift heavy wheel and tire assemblies onto the tire changer or lower them after service. This pneumatic assistance is particularly valuable when processing large SUV and truck wheels throughout the day, where repetitive manual lifting creates cumulative strain and fatigue. By reducing physical demands, the pneumatic wheel lift allows technicians to maintain productivity and precision through longer work shifts while minimizing injury risk from awkward lifting positions and heavy loads.

Regular maintenance includes daily inspection of pneumatic connections for air leaks, weekly lubrication of moving components per the maintenance schedule, periodic inspection of the PowerMont tool for wear, and replacement of air filters and moisture separators in the compressed air supply system. The dynamic bead breaker mechanism requires periodic lubrication and adjustment to maintain proper synchronization between upper and lower disks. Following the manufacturer's maintenance schedule documented in the operation manual is essential for reliable long-term performance and maintaining warranty coverage. Neglected maintenance can lead to premature component failure and reduced operational efficiency.
