Tyres and the environment

The greatest effect which tyres have on the environment during their life cycle is related to the fuel consumption of the vehicle. For years, tyre developers have strived to decrease the rolling resistance of their tyres, and in doing so, the fuel consumption of vehicles. A tyre is like a decathlete – it needs to […]

Important selection criteria included the refrigerator having a lot of storage space, integration of a freezer unit, and ease of use of the washing machine and tumble-dryer. All appliances had an energy-efficiency rating, which could be used to organise devices […]

Differences in testing in summer and winter time

The biggest challenge for the development of tyres is to find the happy medium between several desired properties. There are dozens of different properties that continuously contradict each other. For example, it is easy to develop easily rolling tyres – you just design tyres with a low rolling resistance. But at the same time, you […]

Developing the safety properties of tyres from expert’s point of view

Safety tests of tyres can be roughly divided to two different subareas: structural tests and live tests. The structural tests of tyres are governed by certain authoritative requirements that must be complied with. Only after this, other properties can be customized. This means that there are various standards valid in Europe and other countries and […]
