Making magic with fragile webs
In Mladá Boleslav, they say that tyres are like black magic. People expect a lot from a tyre: it shouldn’t be noisy, it should have optimal rolling resistance, run smoothly in dry weather, brake effectively on wet surfaces, perform well in different temperatures, have good traction in order to effectively transfer the engine’s power to the road, and minimise sliding. Very often, however, these requirements are mutually exclusive.
“We can visualise this set of requirements as a web, with all the individual properties of the tyre at each end. The moment you pull one end, you inevitably affect the other properties as well. For example, if you improve rolling resistance you diminish the braking distance or traction on wet surfaces,” says ŠKODA’s Jan Ševčík. Companies try hard to develop new materials with generally better features, but the process is complicated and requires use of advanced, almost space-worthy, technologies.
When it comes to choosing tyres, you need to keep an eye on several key important parameters to ensure that they will be a good fit for your car. This is why there is an information label on each tyre, setting out all of the important information.
