Runflat CBR is developed in house by our research, development and engineering team, with some static evaluation carried out by our neighbours at Boeing’s Advanced Manufacturing Research Centre. Latest CAD software is used and pre-prototype components undergo in depth FEA (Finite Element Analysis) and FMEA (Failure Mode and Effect Analysis) in order to gain real data on wheel, tyre and vehicle dynamics for most conceivable runflat scenarios, prior to static, and then track testing.

Runflat CBR supports the tyre centrally on the wheel and across a larger area than conventional systems, reducing localised pressure, friction and heat build-up, spreading the load across the runflat and so increasing runflat distances.

The unique lightweight friction reducing device built in to Runflat CBR’s design further reduces heat build-up and this increases runflat distances. Furthermore the ‘wrap-around’ design greatly assists lateral and kerb strike protection.

Runflat CBR’s unique cantilever design means less material may be used in its construction and this contributes to reduced weight.

During fitting, the cantilever effect exerts side forces on both tyre beads to create a strong beadlock. When running flat the greater loads and external forces enhance this lateral loading and beadlock force.
