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.

27.08.2026 from Chris J
Driving mostly continental major routes to Spain 4 times a year Grip handling and comfort are excellent Tyre wear is very good with the last set completing 48000 miles and only changed then due to outer edge perishing, sun being the culpritI suspect
27.08.2026 from Chris J
This is my second set of Nexen Fera Sport. They are excellent and generally very quiet. Grip is excellent and wear very good. Fuel consumption is 64mpg on a motorway run and 57 in local driving. The first set lasted for 48000miles and were only changed due to outside edge perishing!
27.08.2026 from Chris J
This car generally completes short commuting runs in all weathers. Grip is excellent and wear good. Outer edge perishing has been an issue with the previous set but that aside very happy
06.10.2022 from John
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,

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.

15.02.2026 from Arska
The tire works quite well on normal asphalt, but on dirt roads the lateral grip is poor. The tire is loud on the highway. The tire wears out really quickly, so I won't buy it again.
02.01.2025 from matheos
These tires are good, but for me, it is not because they are not 195/65/15. they are 195/64/15. So I have problems claiming a ramp because the car find under !!!
18.01.2024 from Rick
Never before had tyres only last 6500kms on my WRX thought it was my wheel alignment had that checked and it was fine massive camber ware when I'm only running 0.5 neg and rear tyres are at less then 50% left so definitely would not recommend at all cheap yes gets you outta trouble but not worth it

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'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'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.
