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.

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

One of the best winter tyres I had from year 2007, when I started to drive my own car. Confident driving also with one side on ice, another on dry surface, on wet snow or just wet surface.

01.05.2019 from Keith
These tyres replaced Pirelli P zero&#39;s so it was a hard act to follow but the only fault I noticed was on fast damp corners they do not hold on just as well
01.10.2018 from Robin Hook
First thing to say is I have MO&#39;s fitted. Tried these on my Stage 3 TT RS - some commuting some shall we say v.spirited driving, grip is excellent, wet &amp; dry but of course the awd helps , as good as others I&#39;ve tried. what is surprising to me is the wear rate they are great, i&#39;m not expecting zillions of miles but to compare I have a mondeo diesel with Michelins doing same commute and only about 20% tops better. Car&#39;s a bit noisy so can&#39;t comment about road noise but again no more/less noisy than other premiums.
20.02.2013 from J Robinson
Definitely my first choice for summer tyres after trying several premium brands. Excellent grip in dry and wet which inspires confidence for spirited driving in all driving conditions.
03.07.2012 from Paul Faulkner
very happy with these tyres

The tires are much more supple than the OEM Bridgestone Ecopias. Ride is much improved. Wear seems better. Ecopias have little tread depth. No discernible change in economy. A great tyre and at about half the price. Have already bought another set for the future in case Dunlops become in short supply!

I have never triggered the ABS in 8 years of using this tyre, except when testing the surface, and have always felt confident even on wet ice! Great tyre, summer and winter.

06.09.2025 from Zoran
I have front set of 2 tires 1 year and around 20000km old, and rear set 6 months and around 10000km. Tyres are excellent for my car on dry and wet. There&#39;s not much snow in this part of England, but was some WET snow last winter and tyres were good on start and in curves but on braking just slide (wet snow i suppose). I have been on the road trip this summer 5000km+, and tyres aren&#39;t worn at all. Good grip in curves on motorway at high speed (up to 180 km/h) on dry and wet.
