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.

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.

15.04.2024 from Phil Gillender
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.

These tyres are good value and perform safely and well when used within legal parameters on UK roads. One slight negative is road surfaces can sometimes make tyre noise quite high but other than that I will definitely buy them again.
12.09.2024 from Michael
The tyres were 7/10 when I got them, the wet straight line grip is great the dry performance is above average. Quiet and comfortable tyres. The tyre wear is poor, I had new arms,tie rods, drop links and bushings as well as alignment done afterwards. The tyres showed excessive wear on the edge after only 8000 miles. I always check tyre pressure every week.

07.10.2023 from Simon Hall
Amazing tyres, grip is excellent, comfort and noise are excellent. the only thing i can fault is that the wear isn't anything special. Down to 4mm after 6000 miles. My tyre size is 245/35R18 but tyretest will not let me add the correct size above.
10.08.2023 from DanB
Excellent tyres chosen via the reviews by Jon @ tyrereviews.co.uk - they faired very well against the likes of the Michelin PS5s and at the time of buying (Feb2023) the Goodyears were £250 cheaper than the PS5s; but more or less neck & neck with them in the tyre review! That swung the decision for me, more so with the money saving!

07.02.2022 from Spiros
Car Driven : BMW 425D 225Hp . Quite quietly from the start until the first 10,000 km they kept a relatively low noise level until the end of their lives. Relatively comfortable especially considering that is a runflat tire. The tire tread still retains its original groove and design but has significant wear points on both edge and there are some small tire detachments. In the few rains we have in Greece it never had a hadling problem or breaking and did not create any feeling of insecurity. in short it is a good quiet tire ROF tire, comfortable and efficient in fast 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'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.

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.
