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.

24.07.2025fromMatthew A McCrae
These tyres give me everything I ever needed from a tyre. Not only are they brilliant in the open road. The confidence they allow when cornering is quite remarkable. I have learned to trust them as I do the Michelins on my motorcycle.
22.07.2024fromMike Greenfield
Excellent amount of grip yet keeping some subtlety even though they are 32psi as recommended. Tyre wear seems reasonable given the performance level and economy appears as good as any. I would buy these again when it becomes necessary. Excellent!
12.04.2024fromMr Badger
We already had two of these tyres fitted to the car so when the other two needed replacing we matched them. They perform well in all conditions wear evenly and are good value. Would definitely buy again for a small city car.

This was the second time I have purchased this set of winter tyres. Winter 2023 I drove across Czech republic where a heavy snowfall suprised us on the way. With those tyres absolutely no problem, felt safe.
26.04.2024fromHamish Reid
Able drive through dry snow >15cm and on incline. Had one drive on wet snow that was up to 15cm in depth which only had minor slipping.
09.05.2022fromEamon Quirke
All good 👍
12.01.2022fromLee cook
Tyres have performed well so far it's still early January so haven't been able to test their performance in the snow yet but they feel reasuring in the wet the car needed tyres when we brought it so a wear comparison will be difficult but I expect then to wear quicker than standard tyres as the compound is bound to be softer on a winter tyre

These tyres work really well in the wet or the dry road conditions. I also think that they are quite quiet compared the previous set of tyres I had on this vehicle. All round these are a great choice.

A decent budget priced winter tyre. Very impressed with the grip quality in snow
