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.

Car Driven : BMW 425D 225Hp . Quite quietly from the start until the first 10,000 km they kept a relatively low noise level until the end of their lives. Relatively comfortable especially considering that is a runflat tire. The tire tread still retains its original groove and design but has significant wear points on both edge and there are some small tire detachments. In the few rains we have in Greece it never had a hadling problem or breaking and did not create any feeling of insecurity. in short it is a good quiet tire ROF tire, comfortable and efficient in fast driving.
31.12.2021 from Stuart
Big improvement on the OEM fitted brand. More refined, quieter and more confident grip in both wet and dry. Fitted full set; 215/45R17 in front and 245/40R17 in rear, as standard spec. Only driven on road (A and B roads and some motorway), no tracking. Hard to fault for this purpose.
16.07.2021 from Rok Sharma
I drive fast and furious when required or slow and deliberate in slow traffic! I used these tyres on my 5 series BMW 525iSE and were superb! Now on Mrs Peugeot 308 hdi and pretty good!

Handling it depends from road quality, but never excellent. Steering feeling is good. Breaking on dry roads insufficient, ABS function even in middle breaking situations. Very low noise,

07.12.2025 from Padraic Tierney
so after 14 months/25166 km of driving these tyres are down to 3 or 4mm on the front and 5.5 mm on the back. I&#39;ve never had any need to brake hard in the wet but i have corned sharply at 90 km/hr using these tyres and they do hold the road well. I know i should rotate these but its hard to get time for everything. They are very good value but maybe a bit noisy on the road. I bought 4 together and at &euro;120 each when you compare to michelin pilot sport is really great value for money. They are wearing fairly evenly too so overall the verdict is i would highly recommend these.

18.12.2025 from Keith
Unlike some who write stuff thinking they&#39;re lewis hamilton, im not, but im no miss daisy either. Ive driven it pretty hard at times and whatever has been thrown at these tyres, wet or dry, they have stood up to it. Not a hint of losing it. Exactly what you expect, from mid range premium make tyres.
30.08.2024 from Clive Smith
These are the B-Silent Model and they were 235/55 R19 105Y but this system will not let me specify 55 height. These tyres are absolutely brilliant! I fitted them on the rear and they stopped the road noise from the rear completely. I just wish I had not fitted something different to the front previously, as soon as the fronts wear out I will change to these. I have had no problem with grip, despite racing others around roundabouts.
28.10.2021 from Fluster
Excellent in the wet, no hydroplaning or wheeljerk when driving into puddles at speed. This is my second set of this tyre for this reason.
13.10.2021 from Agop Beyleryan
The tyre is with overall good performance. On wet is losing grip in the corners, however braking in wet conditions is solid
