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.

I had no snow this year so have to leave the impression that they do not perform. This false reading is a function of the survey&#39;s unintelligent layout/creation!! These are great tyres on Scottish winter(!) roads and I am still using them in summer without obvious wear. My old van will not see another winter so I will never know about their snow-go! Whatever I drive next will have tyres like these if the price is similar. I don&#39;t drive fast but I don&#39;t brake much and these are like glue in a corner!

The best tyres for the money!
25.05.2019 from Paul Verona
My local fitter advised the Nankang&#39;s as I was initially looking at BF Goodrich as they have &quot;B&quot; wet grip rating but there were none in the country and no expected delivery. The wet ratings are at summer temps which means that winter Nankang&#39;s with a &quot;C&quot; wet rating are much better than the summer Potenza&#39;s with an &quot;A&quot; wet rating when the temp is below 7degC. I decided to get some winter tyres after getting stuck the previous winter on Potenza&#39;s and discovering that trying to fit snow socks to a Fiesta ST when it&#39;s stuck in snow is not possible. This year I did not have much snow and the Potenza&#39;s would have coped but the car felt very sure footed. There were many mornings when the temp was below 7deg C and the Nankang&#39;s performed very well - much more confident than the Potenza&#39;s. Tyres gave very good braking and cornering grip, wet and dry. Slightly noisier than the Potentza&#39;s but not overly. Kept the tyres on from Nov-April and when they came off they looked like new. On returning to the Potenza&#39;s there is a noticeable improvement in grip, but now the temp is 10degC+ so is expected. Can&#39;t comment on the economy as most of the journeys are short and traffic dominates the mpg. I will definitely be refitting them for next winter.

Always a bit wary of trying a new tyre, but these tyres are great

These Trazano Z107 tyres were initially adequate as budget tyres but over time they have become noisy at speed and wet grip is now atrocious - with 5mm of tread still on the tyre. A regrettable purchase. I will revert to my usual Pirelli Cinturato which performed admirably right down to the tread wear markers. Lesson learned.

These tyres work really well in the wet or the dry road conditions. I also think that they are quite quiet compared the previous set of tyres I had on this vehicle. All round these are a great choice.

A decent budget priced winter tyre. Very impressed with the grip quality in snow

21.02.2026 from Alan Marshall
Fabulous tyres and exceptional wear, considering the price point of these, especially given my driving style. I&#39;ll definitely see over 20000 miles on these tyres which I find remarkable on a heavy car with over 400hp. Could I have better grip, sure for twice the price. Do you really need it, even for having fun on UK roads, no! They are soft rubber though, so you&#39;ll know if your alignment is out, these didn&#39;t last long on my Merc V Class!
08.08.2020 from Dean
Doing relatively high mileage of over 40k every year, I&#39;ve been through various different premium tyres over the years. Let me tell you, in the 5k miles on these tyres so far I&#39;d say they&#39;re pound for pound up there with premium tyres for everyday driving. I&#39;ve found them to be really good in the wet, no major drama with aquaplaning and my heavy right foot has encountered no issues in cornering. Strangely, I&#39;ve found that I&#39;m more confident with these in the wet than dry- they tend to be slightly unpredictable when pushing on. Not a massive issue by any means and shouldn&#39;t put anybody off, it&#39;s just highlighted by my spirited driving style! Wear seems to be decent so far, but as I said I&#39;ve only done 5k so far so too early to tell. All in all, great value for money and worth a try. On 20&#39;s, The Goodyear Eagle F1s that I had on previously were &pound;160 each, whereas I got these for &pound;115. 200 quid saved, and genuinely no worse performance. Well done Viking!
18.10.2019 from W Edbury
The car feels very safe cornering and braking is very good , it drives straight no wandering overall I&rsquo;m very satisfied with the set of Tyres.
