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.

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&#39;re a good looking tyre also! :-)

30.05.2026 from Fraser
Have tried lots of different snow tyres over years and put these on my 3 series touring to replace the Pirelli zero&rsquo;s. If anything I thought they ran quieter than the zero&rsquo;s and plenty of grip in both dry and wet conditions. Used the in snow as well and kept everything moving which is all you want from a snow tyre.
15.01.2026 from James
As my Volvo is a rear wheel drive automatic I always use winter tyres. Previously had Goodyear ultra grip 9 and still have them on the front. New Goodyear ultra grip 3 on rear. We&#39;re great in the recent snow, where front wheel drives were getting stuck, no doubt on summer tyres.
11.01.2025 from Andy Duff
An extremely sure-footed winter tyre that blurs the transition from my summer to winter wheels. As good as it gets.

21.05.2023 from Alan Clarke
I&#39;m a taxi driver out in rural Essex, I drive on all types of roads including Motorways, A roads, B roads, all types of country lanes, farms, you name it I go on it. the tyres have to put up with a lot of stressful driving conditions and the have coped brilliantly and no signs of wear yet. Michelin are the best tyre I&#39;ve used. Also I use 235XL for xtra grip, and my car is a Galaxy Titanium 7 seater 17inch wheel.

I have used vredestein snow tyres for 35 years they are amazing now I don&rsquo;t change them and use them all the time they last about 30000miles
09.11.2025 from Tony Jenkins
I drive across Europe on many different roads. I&rsquo;ve used this tyre on several different cars. It&rsquo;s excellent
04.05.2025 from Tim Morgan
So much more secure in all adverse driving conditions heavy rain slush and packed snow in north of Scotland. Superior in all aspects compared with OE tyre but must always have steering assistance with these new minis disabled
13.09.2024 from Philip Purvis
These tyres are a long lasting winter tyre which I keep on the car all year, so far I haven&#39;t driven on snow with them but have been on the car all summer, normally a time when winter tyres wear more.
