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.

12.12.2025 from DAVID
These tyres are outstanding. The car is a 25th Anniversary GTI with a ported and polished cylinder head and fitted with SACHS Race Engineering coilovers. I require tyres with the highest possible grip, in both wet and dry conditions. For this reason I only fit AUDI AO specification tyres as this specification was developed for the maximum grip on the high performance fwd Audi TT. Which uses the same platform as the MkIV Golf.
18.09.2022 from DAVID
These are as close to perfect summer tyres that I have come across in more than 50+ years of spirited driving. Wet grip is of great importance, and these tyres are actually AO, which I always purchase, as I understand that grip was paramount in AUDIs requirements. The car is a modified 25th Anniversary model and is fitted with SACHS Race Engineering Coil-Over suspension. The cylinder head has been ported and polished with the motor now producing well over 200 ps.
14.06.2021 from y2kdisease
Car had 20&quot; 245/35r20 runflats in front and 275/30r20 runflats (all MOE) for RWD w213 luxury saloon. The car came with these factory fitted MOE runflat tyres. I&#39;ve Replaced these tyres and wheels at 10600km. I&#39;ve driven 8600km of that mileage. The tyres wore like rubber bands on the 20&quot; wheels. Steering as a result is very precise in both wet and dry. Front 245/30s have sound deadening foam and overall tyre noise is quiet in the cabin (but just wee bit louder than the 18&quot; PS4 tyres I replaced them with). Ride comfort is 8/10 on highways due to air suspension. On chip seal, speed humps, potholed roads ride comfort is 5/10 - there is very abrupt jarring transmitted to cabin due to tyre profile and rims. Wet grip in cold (5&#39;C) and damp country highways was 7/10 at 110km/h speeds - there was some slip noticeable. Dry grip was 8/10 most of the time but with occasional rear traction slips at highway speeds in curves. This combination of tyres and rims is quite poor for a luxury sedan and compliant rides.
06.06.2020 from Chris Farnell
These tyres are great. Low road noise, and surprisingly grippy in the wet. Like really grippy

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 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.
