In general, the following applies: All approved wheel/tyre combinations are valid for both summer and winter tyres. Nevertheless, winter tyres are specifically mentioned in e.g. part-specific technical reports. The recommended winter tyres differ from other tyres in two main aspects: The speed index (indicated in the last letter of the labelling on the tyre) and the diameter.
Winter tyres generally have a lower speed index as road conditions tend to be very different in winter. And: The larger a tyre or wheel, the smaller the amount of space available for snow chains. That’s why the recommended winter tyres tend not to be the largest size that is permitted for the respective vehicle.
