At EDEX 2018 in Cairo, 3-5 December, Tyron will be showcasing its rubber runflat tyres, which have been trialled on Egyptian Defence Force TIMSAH (CROCODILE) 4x4 tactical vehicles.

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 types 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 and reduces the logistical tail, whilst giving the crew and passengers as comfortable a ride as possible,” commented the Technical Director of Tyron Runflats, Tony Glazebrook.

The use of rubber, as opposed to 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, whilst retaining a degree of 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 be done with rubber. A hard composite needs to be manufactured to an exact size and if there is any error in the beadlock on the tyre, then the chance of losing beadlock increases.
