Tyron Runflat delivers additional wheel-tyre-runflat assemblies for British Army Ridgback and Mastiff armored patrol vehicles.

Under the British MoD’s Protected Mobility Engineering & Technical Support (PMETS) contract, NP Aerospace is re-engineering 4x4 Ridgback and 6x6 Mastiff vehicles to improve their off-road mobility performance, enhance safety and introduce new capabilities. Improvements being carried out on the fleet include installing an industry package of equipment: new independent suspension systems incorporating Ride Height Control; upgraded driveline, steering and braking systems; central tyre inflation systems; and increased diameter tyres.

Tyron is responsible for delivering the entire wheel assemblies to NP Aerospace for the upgrade, consisting of its All-Terrain Rubber Multi-Piece (ATR-MP) run-flat and the new Michelin X Force ZL16.00r20 tyre, which has a new deep, open tread pattern and shoulders to maximise traction. Tyron is the first company in the UK to take delivery of this new tyre and integrate it into the wheel assembly.

The ATR-MP contributes to increased mobility and safety for the Ridgback and Mastiff vehicle fleet, while also supporting simplified logistics in the field. As a multi-section run-flat, the ATR-MP does not require any special tools or a hydraulic press to insert and remove the runflat when replacing the tyre, as is the case with single piece alternatives.

Tyron’s ATR run-flats are designed to maintain vehicle mobility and safety during and after tyre deflation, whether due to ballistic attack, blowout, or puncture, allowing the driver and crew to continue the mission safely and return to base. The run-flat guarantees beadlock, which prevents the tyre from spinning on the wheel when deflated, enabling the vehicle to continue moving at speed in full compliance with on and off-road Finabel standards. The system is fully compatible with CTIS and standard wheels.

The first batch of wheel assemblies was delivered for the programme in early 2021.

“This new batch of assemblies, incorporating the new Michelin tyre with the ATR-MP will deliver improved mobility and safety for the Ridgback and Mastiff vehicle fleet in support of Operation NEWCOMBE in Mali,” Peter Simson, Director, Tyron Runflat, said. “We are pleased to be part of this industry team delivering an improved capability for British forces operating the Ridgback and Mastiff vehicle fleet.”
