Run-Flat Tire Changing Machines
for Armored Vehicle Readiness
Military-grade tire changing systems engineered for run-flat insert removal, multi-piece rim disassembly, and heavy tactical tire servicing — workshop, containerized, and trailer-mounted variants.
Military Tire Maintenance
Is a Readiness Problem
Armored vehicle tire failures affect mobility, mission timelines, and force protection. Run-flat inserts — heavy, rigid, and critical — demand controlled handling.
Manual Handling Risk
Run-flat inserts weigh up to 80 kg. Manual removal with pry bars creates crush and musculoskeletal hazards.
Extended Downtime
Without dedicated equipment, a single tire change can exceed 4+ hours — impacting fleet readiness.
Multi-Piece Rim Hazards
Lock rings and side rings under stored energy can cause catastrophic separation if improperly handled.
Sustainment Gap
Forward units lack standardized workflows. Improvised methods create inconsistent outcomes and risk.
Run-flat insert handling requires controlled hydraulic equipment — not improvised manual methods.
Compatible with Key Military
Vehicle Platforms
GM Defensive run-flat tire changing machines support tire and run-flat insert servicing across major armored and tactical vehicle families deployed worldwide.

Heavy tire assemblies exceeding safe manual handling limits; run-flat insert weight demands hydraulic assist.
Stryker 8×8
Eight-wheel platform requires high-throughput tire servicing capability for depot-level maintenance.
JLTV
Tactical run-flat tire assemblies with integrated CTIS; rim and insert servicing requires controlled equipment.
HEMTT
Large-diameter heavy tactical tires; significant weight and torque requirements for rim separation.
APC
Armored personnel carriers with run-flat inserts across varied rim configurations and tire sizes.
BearCat
Tactical law enforcement and security vehicle with run-flat capability requiring specialized maintenance.
Tactical Trucks
Military logistics and transport vehicles with heavy tire assemblies and run-flat requirements.
Choose the Right Machine for
Depot or Field Operations
Three deployment configurations — same core capability. Select the variant that matches your operational environment, maintenance doctrine, and deployment requirements.
Workshop Model
Permanently installed run-flat tire changing system for high-volume armored vehicle tire servicing in depot maintenance facilities, garrison workshops, and national maintenance centers.
- High-throughput tire servicing
- Permanent facility installation
- Full hydraulic operation
- Multi-vehicle compatibility
Container Model
Complete run-flat tire maintenance capability integrated into a standard 20-foot ISO container — deployable to forward operating bases, remote maintenance sites, and austere environments worldwide.
- 20ft ISO standard container
- Self-contained operations
- Rapid deployment
- Climate-controlled option
Trailer Model
Trailer-mounted run-flat tire changing system for mobile field maintenance, recovery operations, and fleet support — deployable directly to vehicle locations in operational and training environments.
- Rapid field deployment
- Tow-behind mobility
- Independent operation
- Recovery team support
Variant Comparison
| Attribute | Workshop Model | Container Model | Trailer Model |
|---|---|---|---|
| Best Use Case | Depot / garrison maintenance | FOB / remote / austere sites | Mobile field / recovery support |
| Mobility | Stationary | Deployable (truck/rail/ship/air) | Tow-behind to location |
| Power Independence | Facility power | Self-contained generator option | Independent power unit |
| Deployment Environment | Maintenance bay / workshop | FOB / remote base / port | Field / training area / convoy |
| Ideal Buyer | National MRO, depot units | Deployed forces, contractors | Field maintenance, recovery teams |
| Throughput | High volume | Medium volume | Mission-critical / on-demand |
Built for Armored Vehicle
Run-Flat Insert Replacement
A standardized, six-step process for safe, repeatable run-flat tire servicing — from wheel handling through final inspection.
Wheel Assembly Handling
Secure wheel assembly positioning using controlled hydraulic handling — eliminates manual lifting of heavy military tire assemblies.
Rim Separation
Controlled hydraulic bead breaking and multi-piece rim disassembly with integrated safety guards for lock ring and side ring handling.
Run-Flat Insert Removal
Hydraulic extraction of run-flat insert from wheel assembly — controlled force application prevents insert and rim damage.
Run-Flat Insert Installation
Precision installation of new or inspected run-flat insert — correct seating verified before rim reassembly sequence.
Wheel Reassembly
Sequential multi-piece rim reassembly with controlled torque application and lock ring engagement verification.
Inspection & Return to Fleet
Final quality inspection, inflation, and release — wheel assembly returned to fleet-ready status with documented service record.
