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.

19.11.2021 from Ian Burton-Palmer
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

14.06.2020 from johan silkenas
Smooth and absolutely lovely on snow, sensational grip. Great feel of safety on wet roads. Used to drive with Pirelli Sottozero 3 winter-tyres which are great too however these GoodYear UltraGrip Performance + winter-tyres are a new level of tyres.
28.05.2020 from Will
I drive an automatic which is terrible for grip with only the slightest snowfall, and I’m very cautious in sub zero icy weather. However with the UltraGrip Performance + tyres I was full of confidence every time I drove in sub zero weather conditions. Breaking distances were further than summer tyres, as expected, but nothing to worry about. Car performance was very good and fuel consumption while motorway cruising was better than summer tyres! There was no snowfall this year so I cannot comment.

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 "step-out" 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.

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.

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.
