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.

These tyres are good value and perform safely and well when used within legal parameters on UK roads. One slight negative is road surfaces can sometimes make tyre noise quite high but other than that I will definitely buy them again.
12.09.2024 from Michael
The tyres were 7/10 when I got them, the wet straight line grip is great the dry performance is above average. Quiet and comfortable tyres. The tyre wear is poor, I had new arms,tie rods, drop links and bushings as well as alignment done afterwards. The tyres showed excessive wear on the edge after only 8000 miles. I always check tyre pressure every week.

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

More comfortable than a lot of winter tyres we have had. A bit noisy but not too bad. Fuel economy better than most.

04.07.2020 from Stewart Dalzell
Just a brilliant all round tyre for the price point, been using them on my VW and parents cars for a good few years, mileage out them is not great if you drive on the limit all the time, but they inspire that as they grip very will in the dry and the wet, as per usual Cooper tyres have always been good on british roast with typical british weather - Also part of the Avon tyre lot, associated Chinese brands are Superia, Austone, Fortune etc, if it&#39;s B or A rated for wet you can almost guarantee it to be the case these days.

These tires are Continental Viking 6 clones (compound, sipes, grooves, pattern, literally everything, compare yourself), branded differently and hence cheaper.... Believe me, these are very good! Buying chinese winter tires is like gambling, you never know how they will perform as the reviews are non existant for the specific tire / brand or very few.... but im here to say, these are maybe the best winter tires ive had... they are not as good as Nordic Friction tires (Nokian Hakkapelitta, well, they are the best Winter tires in the world) but just as good and/or better than the rest honestly.... like Nokian WR D4 or Continental Vik. 6.... infact they are like Continental Vik. 6 clones, you would think they are a fake version of them, but nope, they are just that good.... which is very good...

Good grip, solid performance on rough country roads, and smooth enough on A roads, balanced breaking and no vehicle shudder
05.02.2025 from Dean
I&#39;ve done around 8500 miles so far in mostly poor weather , very good grip in all winter conditions and mild conditions. Good all rounder.
28.05.2024 from Marcis
Good grip on wet and dry roads. Reasonable grip on snow and icy roads. Noisy on dry roads. Fuel consumption has increased. All in all decent tyres.
07.04.2024 from Harry
Incredibly capable tyre for all conditions, but my experience on the roads in West Yorkshire will probably dictate that I don&#39;t purchase these tyres again as they are too soft on the sidewall, they do need some sort of protective band. The roads a terrible around Haworth for potholes, and in this case I could not dodge one and it has ripped the sidewall and damaged the rim, rendering the tyre scrap.

Amazing tyres, grip is excellent, comfort and noise are excellent. the only thing i can fault is that the wear isn&#39;t anything special. Down to 4mm after 6000 miles. My tyre size is 245/35R18 but tyretest will not let me add the correct size above.
10.08.2023 from DanB
Excellent tyres chosen via the reviews by Jon @ tyrereviews.co.uk - they faired very well against the likes of the Michelin PS5s and at the time of buying (Feb2023) the Goodyears were &pound;250 cheaper than the PS5s; but more or less neck &amp; neck with them in the tyre review! That swung the decision for me, more so with the money saving!

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.
