RunFlat International Ltd
RunFlat International is the leading independent RunFlat systems and military wheel supplier in the defence and security sector, having built a reputation on quality, performance and customer care.
Our RunFlat systems are tyre inserts bolted onto the wheels and designed essentially to allow the driver to control their vehicle and enable them to drive on safely following ballistic or terrain-related tyre damage (to one or more tyres). While the tyre is fully inflated, the tyre insert has no effect on the performance or handling of the vehicle.
If the tyre becomes deflated, the tyre insert prevents full deflation and enables the vehicle to continue its journey until its passengers and contents until a safe place is reached. The RunFlat systems do not affect the handling characteristics of the vehicle being driven in run flat mode, whether on or off roads.
Designed primarily for the armoured vehicle market, we offer a complete range of wheels and RunFlat systems to suit all vehicle applications. When the RunFlat system is fitted, up to 100km can be achieved with deflated tyres following ballistic or terrain related damage.
Our products are well proven and regularly tested according to military standards such as FINABEL 20.A.5 (50km), FINABEL A.20.A (100km) as well as specific standards established by certain countries or manufacturers.
RunFlat International was established in 2001 as a subsidiary of its parent company Westley Plastics using its leading edge polymer technology to exclusively develop run-flat tyre insert systems.
RunFlat International has full ISO 9001:2015 certification. Operational excellence is achieved through state of the art machinery, polymerisation expertise and regularly audited quality standards.
All our products are manufactured in house from raw chemicals through to complete fitted wheel assemblies. Controlling the process from start to finish ensures full process control and quality can be guaranteed.
Extensive industry experience and a regular global customer base mean our products are well proven throughout the world, with many products still in use after 20 years.
Dynamic RunFlat System
The Dynamic RunFlat is designed for single piece wheels and is therefore suitable to be fitted on the vast majority of cars, SUV’s, trucks and trailers.
The Dynamic System is made of 2 or 3 antiballistic composite segments bolted around the wheel rim which remain fixed on the rim when the tyre is fully inflated but slip in the opposite direction to the forward rotation of the tyre and wheel when the tyre is deflated, compensating for the difference in diameters between the tyres on each side of the axle. Within this range, we offer 4 main run flat capabilities (other variants do exist based on specific clients’ requirements):
a. Dynamic 15km: a light-duty 2-segment system designed and manufactured to cover 15 km at 50 km/h on road in run flat mode.
b. Dynamic 30km: a 2-segment system for cars and 4x4’s or a 3-segment system for trucks designed and manufactured to cover 30 km at 50 km/h on road in run flat mode.
c. Dynamic 50km: a 3-segment system designed and manufactured to cover 50 km on road (3km at escape speed up to 90km/h, 10km at 50km/h and 37km at 25km/h) or 30 miles at 30 mph on road or 40 km off road at 20 km/h in run flat mode.
d. Dynamic 100km: a 3-segment system designed and manufactured to cover 100 km on road (3km at escape speed up to 90km/h, 22km at 50km/h and 75km at 25km/h) or 60 km off road at 30 km/h in run flat mode.
Static RunFlat System
For multiple-piece wheels we manufacture a Static System made of 3 antiballistic imperishable composite segments bolted tightly around the wheel rim which remain fixed and keep the tyre in place whether inflated or not. Its “beadlock” function is particularly strong in run flat mode thanks to its patented shape. This system, primarily designed for military applications on and off-road, typically allows 50 to 100 km in run flat mode:
a. Static 50km: a system designed and manufactured to cover 50 km on road (3km at escape speed up to 90km/h, 10km at 50km/h and 37km at 25km/h) or 30 miles at 30 mph on road or 40 km off road at 20 km/h in run flat mode.
b. Static 100km: a 3-segment system designed and manufactured to cover 100 km on road (3km at escape speed up to 90km/h, 22km at 50km/h and 75km at 25km/h) or 60 km off road at 30 km/h in run flat mode.
The system can be installed with no specialist equipment and typically offers a 20% weight saving over rubber alternatives.
