Tyre labelling

The aim of this new regulation is to increase the safety and the environmental, economic efficiency of road transport by promoting safe, energy-efficient Tyres with low rolling noise levels. Tyre labeling should enable consumers to make more informed choices based on an assessment of these three factors. In addition to the other criteria, usually considered at the time of purchase.

However, it is important to be aware that fuel efficiencies and road safety also strongly depend on driver behavior, in particular the following points:

How to change your tyre size?

When integrating a fitting of a wheel of a modular size for your car, it is necessary to obtain expert advice. Naturally a small and large wheel will bring with it the need to consume and fit a tyre of a different profile (height).

You must maintain a compatible diameter of wheel and tyre. It will ensure that the suspension will not change significantly and the car’s safety will not be compromised. Before changing wheel and tyre size, tyres would recommend checking the guidelines set out by your car manufacturer and it is worth speaking to your insurer, too.

Many drivers choose to fit a taller or wider wheel for cosmetic reasons. The combination of a taller or wider wheel and a lower profile tyre can increase road holding performance, although the comfort of the car’s ride will be reduced. Alternatively, a large wheel with a low-profile tyre can be replaced with the combination of a more standard wheel and a taller tyre. The latter is quite a common practice when fitting winter tyres to a performance car, for example.

Entering your current and desired new tyre size into the calculator below will enable you to see if this is a viable and safe option. If the percentage difference in diameter is more or less than 2.5%, Tyre Planet would not recommend this change.
