Nothing runs without tyres. Nevertheless they rarely get much attention, despite the fact that the black rubbers fulfil many more functions than are apparent at first glance. They should decrease braking distance through their excellent surface grip, and thus increase safety, while also having a low rolling friction in order to decrease carbon dioxide emissions. But that is not all: they should, at the same time, be as light and quiet as possible. These are the factors tyre manufacturers focus on, in order to continually improve the properties of the tyre. The september issue of VIAVISION demonstrates how components, new additives and tyre recycling ensure safety and a good environmental balance.
