Tyron Runflat Flat Tyre Protection for Military and Defence Vehicles

Tyron Runflat

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 users and tyre fitters, 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.

Friction shield for prevention of tyre damage

Tyron has developed a lubrication system to further improve the performance of the ATR. Friction Shield is a sealed lubrication system, which bursts following a sudden tyre deflation and provides the right amount of lubricant by reducing the heat generated by friction between the runflat and the inside of the tyre, to ensure that the tyre is not damaged further.

Friction Shield enables the vehicle to keep moving over longer distances and at faster speeds. Forgetting the lubricant, allowing it to dry out or become contaminated will cause a 90% reduction in the runflat performance.

Friction Shield ensures the right amount of clean, fresh lubricant is delivered when needed.

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 move the vehicle to safety.
