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.

16.11.2025 from Sith
These tyres were absolutely poor on my BMW. The car felt like alignment was off and the car had no stability, going above 60mph was a very scary experience. I removed them and put back my old continentals with 1mm tread and tested because people claimed my alignment was off, but no, it was these tyres they are terrible - nankang ns20. I removed and sold and bought a pair of pirelli p zero
24.03.2024 from Christopher
Fitted to a 140bhp front whee drive car. Taking into account these are a budget tyre, grip in the dry is good and spirited driving can be accommodated safely. Tyre in the wet is good but no tyre is safe on the limit in the wet. Because of my low mileage I cannot comment on the rate of wear but must be realistic, after all it is a budget product.
26.02.2021 from David Finlay
I was sceptical about the quality of these Nankang tyres, when I bought them I was influenced by the price, but I have been pleasantly surprised by the grip level both in the dry and wet. I like to drive quickly but not dangerously and I have felt when the tyres have been close to their limit, which is a big plus point. My only complaint would be they do tend to follow tracks in the road, but they are quite wide.
13.12.2020 from Andrew Williams
For the price I think you will struggle to find a better tyre.

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,

Tyres had side sway when changing lanes. 1st blowout on 20000 2nd blowout on 30000 and at 40000 last remaining Tyres has wall cracks in inside walls of rear Tyres. Definitely a tyre manufacturer problem. Dealer and supplier is saying I overloaded the tyre and drove on flat tyres. The remaining two tyres are available for evaluation.

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.

17.03.2024 from Mr. Terry Brown
When I purchased my vehicle (preowned) it came with Nexen tyres on all four corners. I had to change the two front tyres after a few years and choose Goodyears. Last year I had to change the front tyres again because the Goodyears had worn considerably, whilst still having the same Nexens on the rear of the car since I purchased it. Hence stick with the Nexens. When I need to change the rear tyres I will definitely choose Nexens.
01.06.2023 from Richard Chappell
I was not sure about purchasing these tyres at 1st, but I&#39;m pleased I gave them a go as they have performed brilliantly, Even tyre wear all the way around, kept good shape and performed very well.
10.05.2023 from Andy
Low noise (quieter than the continentals the car had as standard). Good grip all weather tyre. Had several Winguard sports before. Recommended.
19.04.2021 from Alan Bunting

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.

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!

Noisy tires. Every day i hear it around 80kmh. Like your car is defect. This all since i have this bad tires. I dont buy this again.
15.05.2025 from Martijn
Affordable tires. But the biggest problem is everytime the noise around the 80kmh. Like your wheelbearings are defect. I read more complains about this tire about the noise. China tires.... They promise a lot (extreme low noise in the specs... But in real you buy &quot;crap&quot;.
