RUNFLAT CBR

The first system to provide all-tyres-deflated
performance on the single piece wheel.

TECHNICAL
INFORMATION
materials

Materials used in the main body of all CBR Extreme and CBR Escape models is sourced from Dupont. After years of testing Dupont are able to supply a material ideal for our runflat inserts, combining the following attributes:

tickDurability combined with our required shock absorbing flexibility

tickLow friction coefficient

tickHigh temperature rating

tickLight cantilever design

tickOperating temperature range from -40C to 160C

The flexibility provided by its advanced design and material enables the new “Active Beadlock” concept to provide efficient lateral beadlock force into the tyre´s beads. Additional width adjustment is also built in to ensure correct beadlock application regardless of tyre bead or wheel tolerance variations.

Ballistics tests have successfully proved the materials used in CBR Extreme and Escape construction do not shatter, crack or break when shot with 7.62 rounds. Below is a section from CBR Extreme following ballistic testing:

tick7 rounds were fired through the complete runflat in total

tickCBR Extreme and Escape do not shatter, crack or break

tickHigh quality materials used in CBR Extreme and Escape construction

tickBullets pass through the material, leaving small entry and exit holes

tickCBR Extreme can continue to operate effectively after ballistic attack

Bullets pass through the material, leaving very small entry and exit holes as can be seen in the photographs taken after ballistic testing on a standard Runflat CBR. The high quality materials allow the runflat to continue to operate effectively after a ballistic attack.
