The first system to provide all-tyres-deflated
performance on the single piece wheel.
Heavy block of material
Narrow tyre support
Often offset from the centre
Light cantilever design
Wide central tyre support
Transfers loads to wheel centre – weakest point – not designed to support load here.
Directs runflat loads into wheel’s seat area – which is designed to carry load.
*This feature can reduce the need for heavy duty wheels, as wheels are not as stressed as with traditional runflats. This design is endorsed by vehicle OEMs & wheel manufacturers.
When tightened on to the wheel CBR Extreme flexes, introducing a lateral beadlock force. When running flat, vehicle weight loads runflat, increasing the lateral beadlock force.
No beadlock – Allows tyre’s beads to move on the wheel. Grip is lost, decreasing traction and braking capability. Steering control is diminished and the tyre can ‘flail’, overheat and rapidly fail.
Beadlock force keeps tyre in place maintaining traction and braking capabilities. Steering and cornering control can be maintained. Tyre cannot move from side to side and cannot flail, so runs cooler and for longer runflat distances.
Solid, limited shock absorption. Can stress wheel in centre, causing cracking and failure. Hard on suspension and reduces performance and runflat speed capability.
Absorbs some shocks when running flat. Aids control in high speed runflat. Less stress and longer runflat capability. Combined with wider tyre support, runs cooler. Endorsed by vehicle manufacturers
Traditional runflats require grease loose within the tyre cavity, making for messy tyre changes and the necessity for it to be to replace when repairing or changing tyres.
CBR Extreme incorporates an anti-friction component with semi-sealed lubrication. Make tyre repairs and changing a clean operation.
New auto-lube concept. Only deploys lubricant in a runflat operation. Keeps runflat and tyre cavity lubricant free for clean repairs and tyre changes, also a Health and Safety benefit.
In addition to its inbuilt flexibility and active beadlock capabilities, all CBR Extreme and CBR Escape models are width adjustable in order to provide the optimum lateral beadlock force, regardless of tyre make or model.
Removes the possibility that replacement lubricant is not applied after
