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.

16.02.2023 from Alasdair
A solid tyre I&#39;ve refitted to the car several times already. Excellent grip on wet and dry and more comfortable than the SportContact they replaced with marginal difference in performance. Only difference felt was feeling marginally more tyre wall flex if driving very hard in corners but a lovely balance for comfort and excellent grip. They are slightly louder than other tyres which is a minus but worth it for overall performance. Very predictable behaviour wet and dry. Only other downside is Conti shipping tyres with slightly lower than average new tread which makes it a bit more expensive over the life than similar priced tyres from other brands.

Great tyres and the reason why I always come back to Conti&rsquo;s
24.03.2021 from N Moss
More comfortable than a lot of winter tyres we have had. A bit noisy but not too bad. Fuel economy better than most.

Smooth and absolutely lovely on snow, sensational grip. Great feel of safety on wet roads. Used to drive with Pirelli Sottozero 3 winter-tyres which are great too however these GoodYear UltraGrip Performance + winter-tyres are a new level of tyres.
28.05.2020 from Will
I drive an automatic which is terrible for grip with only the slightest snowfall, and I&rsquo;m very cautious in sub zero icy weather. However with the UltraGrip Performance + tyres I was full of confidence every time I drove in sub zero weather conditions. Breaking distances were further than summer tyres, as expected, but nothing to worry about. Car performance was very good and fuel consumption while motorway cruising was better than summer tyres! There was no snowfall this year so I cannot comment.

Only downside to the tyres is cornering tightly , roundabouts in half wet dry conditions slip evident if pushed even a little over normal roundabout speeds . Otherwise a very good tyre in all conditions , wet grip in heavy rain also very good .
10.12.2025 from Stephen Brown
Great tyres, safe and give confidence on all surfaces and conditions
13.06.2025 from stevi
best tyres ever had them on Audi A3 TDI sport ,fiesta st .ford focus MK2,jaguar xj 3Ltdi best grip ever handles in wet like a great tyre does when dry grips so hard in the dry the engine struggles to go faster because of the grip tried all the named brands like Mitchellen ,toyos ,co rentals and the uni royals beat them ever time not just price but grip safety and handling too .never use any other tyre the 5s are better than the 3s but not by much . hard to improve on such a great tyre

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.
