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.

Tyre developed for electric vehicles. These tyres can also be used without hesitation on vehicles with other drive systems.

I am a professional driver in my working environment (emergency services). These tires are rubbish. Any speeds over 50kph in wet weather will cause them to hydroplane.
27.03.2021 from Martin
Tires performed better then expected. Very comfortable and quiet ride. Great dry and wet road driving

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.

Excellent tyres highly recommend

On my second set of these tyres, excellent grip and handling. Good in the wet too
06.10.2023 from Victor
On wet roads, the cornering capability is reduced compared to Bridgestones, however these tyres cost 30% less. All in all, for mixed driving, it&rsquo;s a great all rounder, especially since it&rsquo;s very reasonably priced. A decent everyday tyre. We&rsquo;ll see how long it lasts, but seems promising, so far. Noise level is quite low too.

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.

One of the best winter tyres I had from year 2007, when I started to drive my own car. Confident driving also with one side on ice, another on dry surface, on wet snow or just wet surface.
