Identify the size of your tyre
The exact dimensions of a tyre can be found on the sidewall printed mark. The graphic shows how to read properties and dimensions of the tyre:
 
/
SPEED INDEX:
The speed index indicates the maximum speed intended for the tyre. Up to this value, the manufacturer guarantees optimum operation with the appropriate tyre pressure. The maximum speed allowed for this vehicle is given in the vehicle owner's manual; this information can be used to select the appropriate speed index for the tyre. The speed index is the last mark on the sidewall of the tyre.
 
Load Index
Permissible maximum axle load per tyre in kg. To be found in the registration certificate or vehicle registration document or read directly from the tyre (two-digit number). It is permitted to fit a tyre with a higher load index.
 
Driving safety despite puncture
Runflat tyres are puncture-resistant tyres with reinforced sidewalls. This creates the so-called run-flat property. In the event of damage, this allows the vehicle to continue driving up to a distance of approx. 100 km (and even beyond depending on the product) at a maximum speed of 80 km/h, even if the pressure has been completely lost. Run-flat tyres even prevent the tyre rubber from jumping off the rim in the event of a loss of air pressure. A flat tyre is therefore still a flat tyre, but it loses some of its drama. Note: All run-flat tyres are marked with the symbol "RSC" (Runflat System Component) and may only be fitted in vehicles with a functioning air pressure control system!
 
Tyres with increased load capacity
Reinforced tyres are designed for higher loads than normal tyres. They can be identified by the designation 'RF' (reinforced) or also 'XL' or 'Extra Load'. They are used on vans, minibuses, off-road vehicles, etc. However, their mounting alone does not automatically result in higher load capacity but also requires a correspondingly higher air pressure. Furthermore, the load capacity index specified in the vehicle documents continues to apply.
 
Tyres with extra high load capacity
The "C" in the term C tyres stands for "commercial". These tyres are specially designed for commercial vehicles. These can be, for example, lighter trucks, delivery vans, flatbed trucks or panel vans. In other words: vehicles that have to move higher loads at a comparatively lower speed. The multi-ply reinforced C tyres are therefore even more load-bearing than reinforced tyres.
 
Mobility-optimised tyres
A tyre with a sealing layer on the opposite side of the tyre tread. In the event of a puncture (e.g. by a nail), this layer blocks any loss of air, even if the foreign body causing the puncture is still in the tyre. It is not necessary to stop or change the tyres immediately at the roadside.

Tyres optimised for electric vehicles.
Tyre developed for electric vehicles. These tyres can also be used without hesitation on vehicles with other drive systems.

Original equipment quality: optimum adjustment to the vehicle
Tyres with a special OEM marking on the sidewall, e.g. "MO" for Mercedes-Benz, were developed in cooperation with a specific car manufacturer and the tyre industry. These tyres have been homologated by the vehicle manufacturer and are a perfect match for a specific model. They have been specially designed to highlight or further improve the performance characteristics of the car in question, thus representing the culmination of a state-of-the-art fine-tuning process that perfectly complements the latest technological developments in the automotive industry. Tyres with manufacturer's markings can of course also be used on other vehicles.

Vast improvement in all areas compared to the Dunlops that came off. Particularly comfort and noise are extremely good! Fuel consumption is better, and they're a good looking tyre also! :-)

15.09.2025 from Harry Up
Gute Reifen, siehe meine Sternebewertung. Warum ich hier schreibe, hat einen anderen Grund. Der Reifen hat EU Label B für Nässeeigenschaften, was bedeutet, dass der Reifen bei Nässe gut ist. Das trifft meiner Meinung nach zu, er ist gut. Gut ist besser als durchschnittlich und logischweise deutlich besser, als schlecht. Es gibt x Tests, die etwas anderes als das EU Label behaupten und sagen, er sei schlecht. Meine Bitte daher, wer auch immer zuständig ist: entweder das EU Label ist Unfug, oder die Tests. Beides passt bei diesen Reifen nicht zusammen. Vielleicht fallen sie auch sehr unterschiedlich aus oder passen zu manchen Autos gar nicht. Also nochmal mein persönliches Fazit: ich suchte günstige Reifen mit Berge Label, also offizielle Winterreifen, die bei Nässe gut sind. Meine Wahl fiel auf diese Reifen und sie war richtig. Ich kann die Reifen empfehlen.

I have already 12000 km with this tires and the feeling is very good, even drove with 130 on highway on light rain without any problems, drove on ice roads and it was ok. I gave 4 stars on the show grip because I did not test them yet on show... but overall are very good!
