Run-Flat Tire
Changing Machines
for Military & Armored Vehicles
NATO-compatible, NSN-assigned hydraulic systems engineered for depot workshops, containerized field support, and mobile trailer-mounted operations.
Run-Flat Tire Maintenance
Is a Readiness Problem
In armored fleets, tire service is not routine garage work. Heavy military tire assemblies, run-flat inserts, beadlock systems, and multi-piece rims create safety, time, and readiness challenges.
Heavy Run-Flat Inserts
Military run-flat inserts are difficult to remove and reinstall manually, especially on large tactical and armored vehicle tires. Manual handling creates crush and musculoskeletal hazards for technicians.
Multi-Piece Rim Risk
Armored vehicle wheel assemblies with lock rings and side rings under stored energy require controlled handling to reduce technician exposure and process variability.
Fleet Downtime
A tire issue can remove an armored vehicle from service even when the rest of the platform is mission-ready. Without dedicated equipment, a single tire change can exceed 4+ hours.
Field Maintenance Constraints
Forward locations, contractor sites, remote bases, and recovery teams need deployable maintenance capability — not only central depot support.

Controlled Run-Flat Insert
Removal and Installation Support
The system is designed to support a controlled maintenance sequence for heavy military wheel assemblies, from initial positioning through reassembly and inspection.
Wheel Assembly Positioning
Heavy tire and rim assembly is positioned for controlled machine handling using hydraulic lift and centering systems.
Rim Handling Support
The machine supports controlled pressure application for rim separation and multi-piece rim component handling.
Run-Flat Insert Access
Controlled separation allows safe access to the run-flat insert within the tire assembly for inspection or servicing.
Run-Flat Insert Removal Support
Hydraulic force and guided handling help remove the heavy run-flat insert from the tire, reducing manual handling risk.
Run-Flat Insert Installation Support
The system supports controlled insertion of the replacement run-flat back into the tire assembly with precision positioning.
Reassembly / Inspection
Wheel assembly is prepared for final rim reassembly, torque verification, and inspection before return to the fleet.
Detailed procedures must be performed only by trained personnel using official GM Defensive operating manuals, approved tools, and safety instructions.
Designed for Military Tire Assemblies,
Not Commercial Garage Work
Every capability is engineered around the unique demands of military tire, rim, and run-flat insert assemblies — not adapted from commercial automotive equipment.
CORE Heavy-Duty Hydraulic Operation
For controlled handling of armored vehicle tire assemblies and run-flat inserts. Hydraulic force application reduces manual labor and improves process consistency.
SAFETY Remote-Controlled Workflow
Supports safer distance and more controlled operation during key maintenance actions. Operator positioning can be adjusted for critical force application phases.
SAFETY Safety Shield / Guarding Concept
Designed to reduce technician exposure during demanding tire and rim workflows. Integrated safety features support controlled handling of multi-piece rims and lock rings.
RANGE Large Military Tire Compatibility
Built for tactical and armored vehicle tire assemblies across multiple vehicle families. Supports heavy military tires, multi-piece rims, and beadlock wheel systems.
CORE Run-Flat Insert Removal & Installation
Purpose-built for the core maintenance problem: heavy insert extraction and reinsertion. Controlled hydraulic operation supports repeatable, documented workflows.
DEPLOY Depot and Field Adaptability
Available in fixed workshop, containerized, and mobile trailer configurations. Defense users can select the deployment model that matches their maintenance doctrine.
Built Around the Armored
Vehicle Ecosystem
Defense users rarely buy a machine in isolation. They buy a maintenance capability for specific vehicle fleets, tire sizes, rim types, and run-flat insert systems.
HMMWV / Humvee
Run-flat insert replacement, tire/rim servicing
MRAP Family
Heavy tire assembly handling, large inserts
Stryker 8×8
Wheel and run-flat insert servicing
JLTV
Modern tactical vehicle tire service
HEMTT / Tactical Trucks
Heavy-duty tire maintenance
APC / LAV Families
Armored personnel carrier tire support
