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.

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.

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
12.06.2019 from Tony Galloni
I have used Pirelli P Zeros for about 15 yrs and they are a great tyre

18.12.2025 from Keith
Unlike some who write stuff thinking they&#39;re lewis hamilton, im not, but im no miss daisy either. Ive driven it pretty hard at times and whatever has been thrown at these tyres, wet or dry, they have stood up to it. Not a hint of losing it. Exactly what you expect, from mid range premium make tyres.
30.08.2024 from Clive Smith
These are the B-Silent Model and they were 235/55 R19 105Y but this system will not let me specify 55 height. These tyres are absolutely brilliant! I fitted them on the rear and they stopped the road noise from the rear completely. I just wish I had not fitted something different to the front previously, as soon as the fronts wear out I will change to these. I have had no problem with grip, despite racing others around roundabouts.
28.10.2021 from Fluster
Excellent in the wet, no hydroplaning or wheeljerk when driving into puddles at speed. This is my second set of this tyre for this reason.
13.10.2021 from Agop Beyleryan
The tyre is with overall good performance. On wet is losing grip in the corners, however braking in wet conditions is solid

Two months in the Alps didn&#39;t need to use snowchains. These tyres gripped well.
20.05.2024 from hoevenb
They are Pirelli tyres so should be good across the board. However the driving comfort in my electric car is not the same anymore with these tyres due to minor vibrations and no I don&rsquo;t have balancing issues so will switch back to Michelin when I need new tyres which won&rsquo;t be anytime soon.

20.08.2022 from Michael
Slightly noisier at low speeds than I had expected (my Cooper winter tyres are quieter) although the relative noise abates at higher speeds. They&#39;re pretty firm on bumpy roads where I drive most often. Superb for motorway driving in terms of low noise and excellent ride comfort.
01.08.2020 from Rob
Great wearing tyre, plenty of grip in the wet and dry. Wearing better the Goodyear F1&#39;s I had on the car before. Will definitely buy again.
29.04.2020 from Mr Doorbar
These tyres were OE on my 2017 Passat Estate so I stuck with the same when it came to replacing the fronts. I&#39;m still on the original rears. The fronts did around 24K miles while the tread left of the rears gives me around another 10K at least. However, the tyres walls on the rear have slight cracking even though they haven&#39;t been curbed and if get worst it will become an MOT failure at the cars first MOT this year. The one area where these tyres are weakest are the road noise. I&#39;m sure there are quieter tyres out there but they may be weaker in other areas. On the whole these Pirellis are more than suitable for any family car.
15.01.2019 from Glynne Gianelli
Seems quieter and more comfortable. Grip very good and economy improved as well.

30.05.2026 from Fraser
Have tried lots of different snow tyres over years and put these on my 3 series touring to replace the Pirelli zero&rsquo;s. If anything I thought they ran quieter than the zero&rsquo;s and plenty of grip in both dry and wet conditions. Used the in snow as well and kept everything moving which is all you want from a snow tyre.
15.01.2026 from James
As my Volvo is a rear wheel drive automatic I always use winter tyres. Previously had Goodyear ultra grip 9 and still have them on the front. New Goodyear ultra grip 3 on rear. We&#39;re great in the recent snow, where front wheel drives were getting stuck, no doubt on summer tyres.
11.01.2025 from Andy Duff
An extremely sure-footed winter tyre that blurs the transition from my summer to winter wheels. As good as it gets.
