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.

Had little snow this year but felt very stable good in wet.No problem s so far
19.02.2021 from Rick von Horvath
Such an amazing tyre from Yokohama. Equally as good, if not better, than both Uniroyal and Yokohama winter tyres that I have used in the past. So much quieter too than winter tyres. Top rated traction on both snow and ice. I have passed taxi drivers and over enthusiastic prestige German car drivers trying to go up steep snow covered hills as the Yokohama BluEarth-4S AW21 just kept on going with confidence and tenacious grip. I would swear blind that my humble Skoda Octavia Combi was a 4 x 4 rather than FWD! I understand that this tyre is TUV Sud approved and I can totally as to understand why. Such good valve tyres so go and purchase some, you will not regret it!
23.01.2021 from Viorel
Surprisingly good grip on wet road and stability. Compares very well with my previous premium brand, season dedicated. Price considered, very happy, would buy again.

Though I&#39;d give these Davanti tyres a go as I&#39;ve seen a few Davanti dealers popping up all over the place. These tyres are reasonably good in snow and ice but the rest of the year it &quot;feels&quot; like you&#39;re driving on snow and ice. Very wayward and &quot;loose&quot; feel to them and a horrible bounce over 50mph like they aren&#39;t round anymore, not a wheel balance wobble but a up and down bounce which is very tiresome on longer journeys. There&#39;s a noticeable hum from the tyres like old fashioned aggressive winter tyres which changes pitch depending on angle of steering. I am a loyal supporter of winter tyres but these are like torture and not worth the grief in my opinion.

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.

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
Excellent tyres highly recommend

These tyres in my rear wheel drive BMW are grippy in the dry, but leave me yearning for more in the wet. The car will &quot;step-out&quot; if I punch it whilst the road is even midly damp. My tracking was done at the same time as having these fitted so that is not a factor. The car will also step out if the road is more greasy looking.

Tyres can be noisy over rougher surfaces but seem to be lasting well. Not really had any snow to speak of to test them on properly but perform well enough in very wet conditions on roads. Fuel consumption seems to be slightly worse than with summer tyres fitted but not too noticeable, getting around 35mpg at each fill up - was getting 35 to 38 with previous tyres.

I&#39;ve already replaced the winter tire for summer tires

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.

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.

03.03.2025 from David Dyson
Mature elderly, x competition experience so not a plodder by any means, retired now so on a budget, these tyres meet that, but excellent performance for the price, also its a must for me that al my tyres are of the same make and compound, went a profile section up from manufactures recommendation, very noticeable increase in grip and handling, only slight negative, possibly due to the excellent torque of my engine ( Turbo Diesel ) and my driving style rather than the tyres, but grip on initial acceleration from stationary even in the dry ( obviously worse in the wet ) definitely not the best, so suspect compound compromise, but nothing serious.
27.05.2021 from fred heath
I like quiet and comfort when driving. These tyres provide that experience as well as a noticeable increase in economy. Being retired I do not have to go out in all weathers but when caught out by the weather these tyres perform well although snow, as might be expected, is a bit of a trial. Despite this I would look for these tires again as they suit my driving style and needs.
13.09.2020 from Marek
Generally... There are no surprises with these tires so far, they work great on wet surfaces, they are quiet, it&#39;s ok. I&#39;m waiting for winter and the first snow.
02.06.2020 from Paul W
Having fitted these tyres all round, they have transformed the car. I used popular well known Japanese brands previously which I had never truly been happy with. I fitted the new tyres and instantly the car felt better, more responsive and considerably smoother. The noise from the tyres was incredibly quiet and I was surprised at how much noise the previous tyres had actually generated. I have also noticed how much better the tyre grips under acceleration and the steering was sharper and more responsive to the touch. There also feels less rolling resistance on the road. I have noticed the tyre pattern looks far better for displacing water and whilst only currently driving in slightly wet conditions, again the feel and response instill a feeling of confidence and safety with good firm grip. Overall I&#39;m greatly impressed with the tyre and would have no hesitation in recommending for performance, grip and safety.
