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.

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

Great.
13.04.2024 from Geof Wassell
Driving within my own ability and the ability of the vehicle I choose to drive is what I do. The tyres on my car are part of the interface between driver and road. I prefer to drive with the tyres fully inflated in order to feel the feedback from the surface of the road through noise, suspension and steering, I ballance throttle and brake response with weather conditions, road conditions and temperature. Tyres with less grip just dictate that I should moderate speed and braking at an increased rate. Noisey tyres provide slightly better feedback than silent tyres. The road with current traffic congestion burden isnt the place for performance spirited driving but is the place where defensive driving must be used. I would describe my tyres as competent.

Excellent driving experience on these tyres. They feel safe, sturdy and solid on the road in heat, heavy rain, slippery roads due to mud, country roads, uneven and good surfaces, I have not yet tried in snow or ice. To any walkers reading this, they feel like vibram soles for my car!
07.08.2024 from peter andrews
tyres only have well below normal 6.5mm tread from new and mine were worn down to 4.1 mm tread after 400 miles plus one developed a bulge. Worst tyres ever only have perhaps 1 years life

These tyres are good for grip and average for comfort, but let down on noise levels.

These are an excellent alternative to the Michelin Alpin A3 which I have historically run. They were cracking before wearing out. I needed something that would stick the power of the vehicle and be controllable. These fit the bill admirably.

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,

18.12.2023 from Jeremy Spillane
I can&rsquo;t yet comment on grip in snow and ice, as I haven&rsquo;t yet driven it in those conditions, although I did buy these tyres to be able to drive in any conditions, all year round. These tyres are only on the front of the car, as these were the only All Season tyres of the correct size for the front of this car. The rear tyres are a larger size, and I have a different make of All Season tyres on the back. The car drive&rsquo;s perfectly with the tyres I have fitted, and it feels very grippy, and quiet, under all conditions. I am very impressed with these tyres and I&rsquo;m confident they will be excellent in snowy and icy conditions as well. It is too early to cont on wear and MPG, but that is not an issue for me.
25.08.2023 from Malcolm Ash
Excellent tyres, have used these tyres on many types of vehicles over the years and they have performed superbly. They are my go to tyre.
01.06.2022 from Marky L
Whilst the grip is good in snow, these tyres really struggle to get the torque down to the road from the the 1.4 Hybrid 215PS during acceleration when the surface is wet OR dry. It&#39;s particularly bad in the wet, where the wheels spin easily. Even on the electric motor drive only, a dab of the throttle to over 80% power sets the wheels spinning at low speed. The Michelin Pilot&#39;s that were fitted as standard have much better grip on the wet roads than the Nexen. Therefore I wouldn&#39;t class the Nexen as &quot;all season&quot;. It should really be classed as a winter tyre only. I wouldn&#39;t like to run these tyres all year round due to the inferior grip in most conditions (except snow of course). I wouldn&#39;t buy this brand if I wanted an all-weather tyre again. I&#39;d purchase a proper winter tyre and swap around in the seasons as I&#39;ve had to do with these anyway!
04.06.2020 from Raf
Overall good tyres. Slightly noisy but not to extend. This is what you would get from all-weather tyre - bit of all. Not most economical on fuel consumption again this is all-weather tyre which is not as good Michelin Cross climate but good for its price.

Excellent wet braking, good snow traction. Dry grip isn&#39;t bad but definitely not as good as a summer tyre with more meat in contact with the road. Relatively noisy tread pattern audible around town when the windows are down. Will vary from vehicle to vehicle. Had these on for six months and covered around 12500 miles / 20k Km. No issues.

Piacevolmente impressionato, gomme silenziose, consumi bassi e ottimo grip. Per una guida 80% extraurbana e 20% cittadina con andatura tranquilla sono veramente ottime. Magari le crossclimate della Michelin saranno pi&ugrave; performanti, ma a questo prezzo &egrave; difficile trovare di meglio.
27.10.2019 from Craig McQueen
Sticks well to the road on corners in all conditions at all speeds. Gives confidence. Tyre is 225/40 R18. Not size available in drop down menu here. Built in kerb protection is welcome on such low profile tyres. Good value tyres, have used this brand for years over about 500,000miles with no issues, lasting 30000 miles plus on drive axles and had 66000miles on trailing rear axle pair!
