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.

I have never triggered the ABS in 8 years of using this tyre, except when testing the surface, and have always felt confident even on wet ice! Great tyre, summer and winter.

23.09.2024 from Kate L
Excellent driving experience on these tyres. They feel safe, sturdy and solid on the road in heat, heavy rain, slippery roads due to mud, country roads, uneven and good surfaces, I have not yet tried in snow or ice. To any walkers reading this, they feel like vibram soles for my car!
07.08.2024 from peter andrews
tyres only have well below normal 6.5mm tread from new and mine were worn down to 4.1 mm tread after 400 miles plus one developed a bulge. Worst tyres ever only have perhaps 1 years life

These tyres are good for grip and average for comfort, but let down on noise levels.

Not a sport tyre. Very disappointment.
26.11.2020 from Alan Burton
Steady, now I'm over 70, with the occasional speed burst for fun. Usually stick to speed limits now.

Quiet & grips well. Gouges very easily on curbs when parking

15.08.2025 from Donald
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.

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'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'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'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'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'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.
