In September 2018 at the DVD Exhibition, Millbrook Proving Ground, Bedford, UK, Runflat CBR was demonstrated on the Off-Road Track. Passengers were taken around the course to experience and witness a new level of runflat performance never before achieved on the normal single piece wheel.
On one set of the vehicle’s standard wheels (single piece drop-centre) and tyres, fitted with CBR Extreme inserts, the vehicle (at all times fully laden) completed 8 hours running flat with all 4 tyres deflated.
The course included:
• 35° ascending and descending gravel hill and 155° breakover
• ditch run
• log run
• snake climb
• sand hills 37° ascending and descending
• twist climb
• rock trails

Demonstrations were witnessed by the British MoD, Dstl, overseas military forces, vehicle manufacturers and vehicle armourers.
• Tyre temperatures did not raise above ambient.
• Tyres were “as new” at the conclusion of the demonstrations.
• Notable during the demonstrations was the flexibility and shock absorption of the runflat inserts, as well as superb steering control and traction.
