Product Overview
M3550EM110
The monty 3550em with patented EasyMont Pro Pneumatic Bead Assist is equipped to handle wheel diamters up to 30". The monty 3550 series is specifically designed to change low-profile, high-performance and run-flat tires, maximizing a shop’s versatility. The pneumatically-controlled mount/demount head eases operator effort while still allowing for manual guidance and movement. The EasyMont Pro holds the bead into the drop center, making one-operator tire changes possible on low-profile, high-performance and run-flat tires.

Features
Accommodates Large Wheel & Tire Assemblies
Allowing for a tire diameter of 47" and an outer-wheel daimeter of 26" on the monty 3550 (30" on monty 3550em), the monty 3550 series can handle wheel and tire assemblies found on cars and light trucks.
Dual Wheel Clamping Cylinders
Dual pneumatic clamping cylinders control all four clamping jaws, eliminating damage to wheels due to slippage.
Four-Jaw Clamping Chuck
Self-centering and clamps wheels with either 26" inner or 24" outer diameter.
Powerful Two-Position Bead Breaker
6,000 lbs. of power at the bead shovel and a range of 17" wide. The two-stage pneumatic cylinder provides precise power and can be toggled with the foot pedal as needed. Both the stiffest and the softest sidewalls are a snap. No damage to the tires while loosening the beads!
Pneumatically-Controlled Mount/Demount Head
Push-button controlled mount/demount head pneumatically lowers and locks into position, automatically indexing away from the wheel to prevent contact and damage to the wheel and tire assembly.
Protect The Most Delicate Wheels
All metal parts have plastic protection providing non-metal-to-metal contact when changing delicate wheels.
EasyMont Pro Pneumatic Bead Assist
EasyMont Pro features a three-piece design with a Top Roller, Pressing Foot, and Lifting Disc. Each piece provides a specialized function that assists a single operator in mounting/demounting low-profile and high-performance tires.
- Assists operator with bead lubrication, wheel clamping, lower bead lifting, re-loosens beads, and allows easy one-operator mounting of the stiff upper bead.
- EAA0329G35B - Standard with monty 3550em (M3550EM110), Optional with monty 3550 (M3550110).
- Top Roller:
- Demounting - Presses down on the tire sidewall, provides clearance for easy positioning of the mount/demount head, upper bead lubrication, and easy insertion of the demount tire lever.
- Mounting - The roller retains the bead under the nose of the mounting head. Works in conjunction with the Pressing Foot to keep the tire bead below the wheel drop center as the tire rotates 360° during the mounting process.
- Pressing Foot:
- Tire Clamping - Presses the wheel in the center hole which allows the lower bead to clear the wheel’s rim for easy clamping.
- Tire Mounting - Presses the upper tire sidewall into the drop center and holds it in place during the 360° rotation required for mounting the upper bead is complete. Allows one-technician operation for mounting stiff sidewall, run-flat and high-performance tires.
- Lifting Disc: Loosens lower beads that often re-seat. To remove the upper bead, the lower bead must be free to move vertically during demounting. Provides an "extra hand" to lift and hold wide tires to facilitate insertion of the demount lever to remove the lower bead.
- For better cosmetic protection of expensive tires and wheels, an optional adjustable bead breaking disc can be fitted to the EasyMont Pro. This disc allows for breaking the tire beads using 360° tire rotation while the disc gently presses the tire bead dynamically, thus preserving tire and wheel.
Quick Wheel Protection Change-Over
Protective parts can be changed quickly from plastic to metal. Even the mount/demount head can be changed over from metal to plastic in a matter of seconds.
