VOLVO

Test Track: RAF Bentwaters, Suffolk. August 1998
Vehicle fitted with Tyron wheel safety bands.

Exploding the front offside tyre at 80 mph, the driver was able to demonstrate control through a series of 45mph to 80mph bends, emergency stops and hard acceleration, reaching speeds up to 110mph. On completion of the demonstration the driver reported that although he was aware of driving on a 'flat' tyre, general handling and control was easily maintained. Despite the approximate 50 mm (2") hole in the side wall of the tyre as a result of the explosion, the tyre suffered no other significant damage. The wheel rim remained undamaged.

With the front offside tyre 'blown' the vehicle was driven rigorously around the DSA track encountering high speed bends, tight left and right cornering, emergency stop, rapid acceleration, slalom and lane change manoeuvres. The vehicle handled well throughout, maintaining driver control, road holding, braking and traction on the flat tyre. At the end of the tests the wheel had sustained no damage.

Tes Trackt: Bruntingthorpe Test Track, Leicestershire.

The caravan tyre was detonated at 113.3mph (recorded by RAC timekeepers) and speed maintained over half mile. The outfit was turned at the end of the track to repeat the run at an average speed of approximately 100mph. On the same tyre simulated 'snaking' trials were performed at 60mph. Then from 70mph an emergency stop was executed, into a coned 'box' approximately 1 metre (3') wider than the caravan. At the completion of all tests the caravan wheel was totally undamaged. No damage had been sustained by the caravan's wheel arch, wheelbox or trim.
