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.

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,

Unlike some who write stuff thinking they'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.
30.08.2024fromClive 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.
28.10.2021fromFluster
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.
13.10.2021fromAgop Beyleryan
The tyre is with overall good performance. On wet is losing grip in the corners, however braking in wet conditions is solid

Super quiet, lovely ride comfort, but also perform brilliantly in the wet. Not had a chance to test this set in snow, but a previous set were excellent on packed snow.
17.06.2022fromM Bradley
Side walls made of Cheese clipped a stone on the road, nothing big, ripped the sidewall, and broke the beading wire, Tyre was 3 days old. in 40 plus years of driving ive never had a bead wire break on a tyre, the garage had never seen one either. contacted continental and was ignored. last time i will ever have these tyre or continental on my vechicals.

These tyres are the best I have ever had. They are excellent in wet conditions and perfect in snow

Have tried lots of different snow tyres over years and put these on my 3 series touring to replace the Pirelli zero’s. If anything I thought they ran quieter than the zero’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.
15.01.2026fromJames
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're great in the recent snow, where front wheel drives were getting stuck, no doubt on summer tyres.
11.01.2025fromAndy Duff
An extremely sure-footed winter tyre that blurs the transition from my summer to winter wheels. As good as it gets.
