Edex 2018: Tyron showcases All-Terrain Rubber runflats.

Rubber runflats trialled by the Egyptian Defence Forces on their Crocodile or Timsah 4x4 are on at the centre of the Tyron display on stand 2600 in Hall 2.

The All Terrain Rubber runflats are multipart units which makes them easy to change with standard tyre fitter tools wherever required thus reducing the logistical burden associated with other type of rubber runflats. “We have developed our All-Terrain Rubber runflats based on conversations with both vehicle OEMs and the end user, in both cases they have told us they want something that enables the vehicle to continue moving at speed, reduces the logistic tail whilst giving the crew and passegers as comfortable ride as possible,” said Tony Glazebrook, Technical Director of Tyron Runflats.

The use of rubber versus composite materials reduces the vibration and stresses that are transmittable through the runflat to the wheels, axles and drive shafts allowing the vehicle to continue with its mission with little change to the handling whilsts retaining some comfort for the crew.

Rubber also has the benefit of ensuring beadlock so that in the event of a puncture the wheel stays locked onto the wheel. This is possible because rubber is a malleable material which can be moulded to fit in a space. Tyron’s runflats are slightly larger so that they really grip the tyre something that can only do with rubber. A hard composite needs to be manufactured to an exact size and if there is any error on the beadlock on the tyre then the chance of losing beadlock increases.

Since 1977 Tyron has been developing a range of tyre safety features which are designed to keep vehicles moving safely at speed and for distances well in excess of standard requirements. In the early 80’s Tyron was contacted by the UK MoD to develop a range of steel bands for the Land Rover steel wheels. These were not only far stronger than the aluminium bands but also solved the problem of ‘catalytic’ reaction between the two different metals where the aluminium bands were prone to welding onto the steel wheels preventing removal of tyres when they needed to be changed.

In 2008 Tyron invented the world’s first ever multi piece rubber run flat All Terrain Runflat (ATR) insert which can be fitted in the field to both military split rims and ordinary tubeless wheels, giving excellent off road capabilities with run flat capability of up to 100 km which far exceeds the Finabel standard. In 2009 Tyron developed the unique R series wheel for armoured 4x4, 6x6 and cash carrying vehicles. This super strong alloy wheel, with a load rating of 1650kg, incorporates an ingenious beadlock design. When fitted with the ATR they allow travel on or off road for over 50km with all tyres deflated.
