CBR introduces


Lightweight cantilever design with patented ‘active beadlock’ technology, shock absorption and sealed lubrication ensure CBR is the best performing lightest and fastest to fit runflat solution and it can be fitted to the normal single piece drop-centre wheel.

A second generation Runflat CBR to meet PAS 301 certification and further exceed Finabel standards has been introduced as a 2nd generation model and uprated to carry heavier static loads and shock loadings to suit a greater range of armoured 4×4 and other vehicles.

CBR is believed to offer best runflat performance by a wide margin over any other current system and is the first of a brand new category for the single piece wheel.

Two CBR types to suit best customer requirements.

CBR Escape

For the lightest weight, suited for highest speeds and 50km or more runflat, including off-road, evasive driving and ‘J’ Turn capability with one or all tyres deflated. Finabel certified.

CBR Extreme

Best suited for longest distance heavy duty and off-road use with one or all tyres deflated. With Finabel and PAS 301 certification.

CBR Extreme & CBR Escape

CBR Extreme

PAS Certified

With CBR ‘active beadlock’ technology both CBR Extreme and Escape are the first runflat inserts to provide all-tyres-down runflat capability on the normal single piece drop-centre wheel. CBR Extreme incorporates a wide central support for the deflated tyre and an anti-friction outer component for longer runflat distances. Its sealed lubrication system makes for clean tyre changing or repair, saving mess, time, cost and environmental hazard.

CBR provides greater steering control than other single piece wheel systems due to its combination of strong patented ‘active’  PAS 301 CERTIFIED beadlock and wide central tyre support with a shaped running surface to keep the tyre centralised when running flat, which is a significant improvement compared to traditional inserts with narrow footprint and usually offset from the wheel’s centreline.

Traction control is maintained even when all tyres are deflated. This is unique for the normal single piece drop-centre wheel. CBR’s beadlock force increases the greater the load applied, ensuring even better beadlock than most runflat inserts fitted to traditional two-piece wheels. Excellent wheel to tyre grip also ensures best possible braking when deflated.

CBR has been ballistics tested as defined by Finabel and remained functional following trials. The materials used in the construction of CBR inserts do not shatter or deform following ballistic attack.

Capabilities include Finabel A.20.A 150km – with all tyres deflated and PAS 301 certification.

CBR Escape


CBR Escape is off-road, ‘J’ turn/evasive/defensive driving and Finabel A.20.5 capable with one or all tyres deflated.

Escape cannot cover the longer distances that Extreme is capable of as it does not incorporate the outer friction reducing component. Instead, Escape incorporates a sealed internal lubrication system within its cantilever design and releases lubricant between the runflat and tyre only when in a runflat situation.

Depending on specific user requirements, extra lubrication pods can be added to increase runflat range where required. Apart from the friction reducing component and different lubrication system all other aspects are the same as CBR Extreme.

*Runflat distance may depend on speed, weight, road surface, driving style and other factors

CBR allows single piece wheels to be used for maximum runflat and all-tyres-down performance and removing the necessity for two-piece or specialist wheels for best traction, steering control, or CTIS operations.

CBR offers the advantages of the two-piece wheel/runflat combination in a much lighter package on the less costly and lighter single piece wheel. Fitting is also simplified.

CBR Military 10 x 20

CBR Military wheel

A second generation Military CBR Extreme has been developed, together with the single piece military specification forged alloy wheel. Suitable for 335/80 R20 MPT tyres, this system provides all-tyres-down mobility on single piece wheels and together represents the lowest weight beadlock/runflat combination available. Uniquely it also allows low pressure and CTIS operation on the single piece wheel.

As with the CBR system for 4×4 vehicles, CBR Military represents a new class of runflat insert and fitted to a single piece drop-centre wheel, in steel or alloy, may render two-piece and specialist wheels unnecessary.

The Company is currently working in conjunction with two defence organisations and a military truck OEM to perfect this second-generation system, while further developing its redundancy back-up features for ballistic attack survivability. Scheduled to be available at the conclusion and sign-off UK MoD and third party trials.

A new single piece military specification forged alloy wheel, suitable for 335/80 R20 MPT tyres. Designed with a choice of 4,000kg or 5,500kg capacity in forged aluminium A6061-T6 and optimised to carry the CBR runflat insert. CTIS can be used with this system, which is unique for the single piece wheel. Available in a range of offsets, PCD and centre bore sizes.

Designed and developed to provides strength with minimal weight and significantly lighter than two-piece wheels. When combined with the CBR runflat insert this is the lightest option available for beadlock plus runflat support on heavier vehicles – an unbeatable saving in unsprung weight.

Manufacturing in forged alloy produces the strongest wheels with great impact resistance for use off-road in the toughest environments.

CBR’s design and production capabilities can accommodate special requirements and the production of small, or volume, quantities.

Fitting CBR to a single piece wheel can be carried out in the field, in the same manner as fitting a normal truck tyre.

Wheels tyres & complete assemblies

Wheels tyres & complete assemblies

We supply various sizes of single piece wheel from 16” to 20” in steel or alloy or we can use your wheels supplied free issue.

Tyres are available from a choice of manufacturers, sourced from manufacturers around the world.

We offer the complete solution from supply and fitting of all components, i.e. wheel, runflat and tyre, or we can fit tyres and/or wheels you supply.

These can be fitted with normal rubber valves or metal security valves, inflated and ready for you to fit on your vehicles. We can also balance the assemblies if requested.

Note that CBR can be serviced without removing the wheel from the vehicle if an optional metal security valve is fitted as this allows the Allen Key, supplied in the CBR Toolkit, to locate on the runflat inside the tyre so tightness torque can be checked at regular intervals.

This facility is an added advantage to ensure the runflat is in optimal condition where a vehicle covers high mileages at speed or through heavy off-road conditions

Traditional Runflat


• CBR is a new category of runflat insert that provides vastly superior performance including all-tyres-down runflat on the single piece wheel
• Ultimate traction is made possible through patented ‘active beadlock’
• Significantly better cornering and steering control
• Longer runflat distances
• Shock absorption
• Sealed lubrication
• Reduced need for uprated wheels through intelligent design
• The unique option to carry out low pressure or CTIS operations
• No internal wheel details/drawing required – for simplified ordering

• CBR in conjunction with a single piece wheel is significantly lighter
• CBR’s modern technology gives longer cooler runflat and at higher speeds.
• Shock absorbing design and ‘active beadlock’ enhances performance. Beadlock force is maintained regardless of tyre bead size
• Lubrication is sealed
• Fitting and servicing is simplified and faster, saving ongoing costs
• Capital costs are less
• No internal wheel details/drawing required – for simplified ordering


In reality CBR is just a small percentage more costly than traditional systems and significantly less costly than the alternative two-piece wheel/runflat combination, despite its better performance than either type. CBR’s manufacturing cost has been driven down through volume injection moulding, innovative design using universal components and the use of modern production methods.

Category 1 inserts only fit single piece wheels, have no beadlock and therefore limited performance.

Category 2 inserts include beadlock, provide better performance (and with more than one tyre deflated), but can only be fitted to heavier and more costly two-piece or specialist wheels.

CBR introduces a new Category 3 runflat insert, where runflat and beadlock are combined and designed to fit single piece wheel, providing the enhanced performance of traditional Category 2 inserts but in a significantly lighter and less costly package.

An important cost reduction throughout the life of the vehicle is another advantage of CBR as its sealed lubrication reduces time when dismounting and refitting during tyre repair or replacement.

When compared to Category 2 inserts on two-piece wheels, fitting is faster, so downtime is reduced and CBR’s sealed lubrication avoids mess, lubricant replacement and environmental hazard.
