In response to a marked increase in spiking incidents around South Africa, SVI Engineering , leading specialist manufacturer of armoured products, has conducted real-world testing to demonstrate the effectiveness of the “Flats Over” runflat tyre safety band system. In recent months, authorities have noted a significant increase in spiking incidents, particularly on main routes around Gauteng and often at night. The modus operandi sees criminals place spikes in the road, puncturing tyres and forcing vehicles to stop or even crash, thus leaving occupants vulnerable to attack and robbery.
In order to simulate such a scenario, SVI fashioned a particularly menacing set of spikes and headed to Gerotek testing facility in Pretoria. However, with the cameras rolling, there was one key difference: the armoured Toyota Land Cruiser 79 single-cab bakkie used for the test was fitted with a set of heavy-duty runflat rings. THE RUNFLAT TEST AT GEROTEK After the bakkie accelerated over the spikes, both tyres on the driver’s side lost pressure.
However, thanks to the runflat rings fitted inside the tyres, the vehicle remained fully controllable, allowing the driver to keep going – and going and going, even after one of the tyres had virtually disintegrated. Once SVI’s allotted time at the Gerotek oval track had come to an end, the runflat rings had seen the vehicle cover 23 km at an approximate speed of 50 km/h, with the wheel itself sustaining no damage. “It’s telling that what.
