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.

Our Company

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.

Complete Wheel Solutions

RunFlat International offer a range of military and security wheels, which offer the following advantages:-

• • High load capacity
• • Custom design
• • Full integration (TPMS/CTIS)

By offering a finished solution, the customer can be confident that the RunFlat system has been fitted correctly and ensures the wheel, RunFlat system and tyre assembly can be fitted straight onto the vehicle.

Tyron has developed a range of solutions to keep wheeled vehicles moving safely in the event of a sudden tyre deflation.

Created following extensive consultation with both end users and tyre manufacturers, Tyron's solutions have been extensively tested and proven in the harshest conditions.

The company's two product families are the Tyron All Terrain Rubber Runflat or ATR and the Tyron Multiband. In both cases these have been designed to allow for the changing of tyres without the need for specialist equipment.

Multipart All-Terrain
Rubber Runflat (ATR)

Tyron has developed and patented a multipart rubber runflat, suitable for fitting to a wide range of military and security force off road vehicles.

Made out of rubber, the Tyron ATR absorbs the shocks from bumps more effectively than a hard composite solution and reduces the damage to both the wheel and the tyre, so that both have the potential of being re-used when repairs have been carried out.

Using rubber also gives the passengers inside the vehicle a more comfortable ride in the case of a tyre burst, which enables them to be in better shape to carry out their task.

The patented multi part design allows the fitter to change a tyre at the side of the road without special tools.

Tyron's rubber runflats are designed with beadlock, which prevents the wheel slipping inside the tyre, this allows the vehicle to continue on its mission and get back to base. This is not possible using other materials.

Complete Wheel Assembly for All Terrain Environments

Working together with Global Wheels of South Africa, Tyron is able to provide a complete wheel and tyre solution fit for the most demanding environments.

These combine the strength of the bolt together with steel or aluminium wheels, along with the multipiece Tyron ATR to provide a very high level of road performance, which is not possible with a composite solution.

Distance and Speed Testing and Ballistic Protection

Tyron's ATR solution has been extensively tested in accordance with the internationally recognised Finabell standards for distance and speed. During all the tests the Tyron ATR far exceed the requirements.

The ATR has been ballistically tested. Five shots were fired into the side of the runflat and two into the tread area from 50m with an AK47 using 7.62mm bullets and an M16 using 5.56mm rounds.

Special effort was made to hit the fixings with one round making a direct hit on the fixing head, which ricocheted off and another hitting the washer and was absorbed.

The other three simply passed through the rubber system. The two shots into the tread area around the fixings were absorbed and none of the shooting had any effect on the performance of the runflat system.

The same test was also carried out at only 25m with the same results. In total, 35 rounds were fired at the runflat with no structural integrity damage.

Multiband for Defence and Security

Developed by Avon Tyres in the 1970s for the Royal Ulster Constabulary, the Tyron Multiband is designed to keep the tyre firmly in place on the wheel, allowing the vehicle to be driven to a safe place to change the tyre.

The Tyron Multiband is in use on a wide range of vehicles including police and fire vehicles, ambulances, and cash-in-transit vehicles.

In all cases where Tyron Multibands are fitted, it is to ensure that the tyre stays in place in the event of a 'blow out' and ensures the driver can manoeuvre the vehicle to safety.
