Run-Flat Systems

Run-flat tire technology is one of the most critical safety systems in any armored vehicle. While comprehensive ballistic protection keeps occupants safe inside the cabin, the ability to continue driving after tire damage can mean the difference between escaping a threat and becoming stranded in a dangerous situation.

Why Run-Flat Capability Matters

In a security incident, tires are often the first target. Attackers know that immobilizing a vehicle makes it vulnerable. A standard tire that loses pressure will quickly become undriveable, trapping occupants at the scene. Run-flat systems provide the critical ability to continue driving 50-100 kilometers even after complete tire deflation, allowing escape to safety.

Types of Run-Flat Systems

Insert Systems (Solid Support Rings)

The most robust solution uses solid rings mounted inside the tire that support the vehicle when air pressure is lost:

• Construction: Military-grade polymer or rubber compounds


• Installation: Mounted between tire and rim


• Range: 80-100+ kilometers at 80 km/h


• Advantages: Maximum reliability, proven technology


• Considerations: Adds 10-15 kg per wheel, requires specialized mounting

Self-Sealing Tires

These tires contain a special lining that automatically seals punctures:

• Technology: Inner sealant layer flows into punctures


• Effective against: Nails, glass, small-caliber rounds


• Advantages: No weight penalty, standard tire appearance


• Limitations: Cannot seal large holes or sidewall damage

Reinforced Sidewall Tires

Factory run-flat tires with strengthened sidewalls that support the vehicle briefly after deflation:

• Range: 50-80 kilometers at 80 km/h


• Advantages: OEM integration, no visible difference


• Considerations: Limited range, stiffer ride quality

Auxiliary Support Systems

Advanced systems that deploy additional support when pressure loss is detected:

• Technology: Mechanical or pneumatic backup support


• Activation: Automatic on pressure loss detection


• Advantages: Minimal impact on normal driving

Performance Specifications

Our recommended run-flat systems provide:

• Extended range: 50-100+ kilometers after deflation


• Speed capability: Up to 80 km/h (50 mph) on flat tires


• Multi-tire capability: Vehicle remains mobile even with multiple flats


• Durability: Systems withstand gunfire, spike strips, and road debris

Installation and Integration

Run-flat systems require careful integration with the vehicle:

• Wheel compatibility: Specialized rims may be required for insert systems


• TPMS integration: Tire pressure monitoring system calibration


• Speedometer accuracy: Verified for deflated operation


• Driver training: Instruction on system capabilities and limitations

Maintenance Considerations

Run-flat systems are designed for easy maintenance:

• Insert systems: Inspected during normal tire changes


• Self-sealing: Standard tire service with periodic sealant replacement


• Service availability: Systems serviceable at standard tire shops


• Replacement intervals: Matched to tire wear for convenience
