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.

Tyres optimised for electric vehicles.
Tyre developed for electric vehicles. These tyres can also be used without hesitation on vehicles with other drive systems.

Smooth ride. Incredible grip that even prevents the traction control from engaging in brisk pull aways from a standstill. (My car is FWD). The only negative with the Michelin Pilot Sport 4 is that tyre wear does appear to be slightly higher than with a regular tyre.
15.02.2024 from David Wood
Flourless great in all conditions even got us home at 40 to 50 mph after running over something in the fast lane of the M5 northbound. Can&rsquo;t praise enough.
09.02.2023 from John Molloy
These tyres are noticeable quieter than my previous tyres, Kumho Exta. Cornering grip is better and fuel consumption is slightly better
09.12.2021 from Nicholas
I&#39;ve driven roughly 22,000km as this was when i would of rebuilt the engine and got the car ready for road, by far these are the best tyres I&#39;ve ever experienced on a car, I had used continentals and dunlop&#39;s beforehand, 2 competitors to Michelin, and before now, I always struggled with understeer under sharp cornering after periods of rain, with the PS4&#39;s, this has been completely eradicated, wet grip is by far the best in its class, with not much coming against it, usually the car would also break grip in wet conditions when in low gears speeding up, this has also vanished, in terms of lifespan, there is roughly 5mm left on the tyres after 22k km, so lifespan is also excellent. I am very confident in using these tyres and will be purchasing again once it comes time to replace.

Used purely as a track tyre. Super focused, brilliant feedback in all conditions. Really competent in the wet as they give huge amounts of feedback and never just go, even when there&rsquo;s standing water on track. Wear is pretty good, I&rsquo;ve done 3 hard track days, one of them being bone dry and they&rsquo;ve held up well. Rears are in great condition and expect they&rsquo;ll last multiple days out. Fronts should do several more days out before changing.

09.05.2014 from Gerry
I don't drive the car hard but even so these tyres have lasted a long time with even wear and still at least 4mm left after 15k. I would prefer more comfort but this is probably due to the 18 inch wheels and not the tyres. They do tramline a bit but I cannot compare to any other brand.
30.11.2011 from Keith Farrow
capable, but for the price there are far better tyres out there. Had PS2's and Conti's before, both gave much sharper handling. The P Zeros seem to wander, and tramline a lot.

25.09.2010 from Alex315
First 15.000 kms tyre is fine, good grip on dry, very good comfort. grip in snow is worthless. braking in wet conditions deteriorates fast after 15.000 kms. at 30.000 kms (and this is for the second time) all 4 tyres (I have FWD, and did not swap front/after) are deformed. driving between 90kmh and 140kmh gives knocking sound. Drinving 105-110kmh makes car shake. Pirelli already changed me 4 tyres and I got 2 for free because of this problem. Now I'm 32.000kms futher and it's the same problem all over again. I am not a sporty driver, and it's too bad I did not know this site earlier. I would never hace let pirelli put me 4 new tyres. Even at 2 for free it's expensive per km.

16.12.2025 from Edward Nunn
these are on my track/fun car and replaced the 20 year old tyres on it which came with the car, they completely changed the performance of the car, for the better, they grip exceptionally, especially when set to optimum pressure for the conditions, and hold traction under very heavy braking. They are as described a dry weather tyre with the ability to just about cope in the wet, and my experience is of dry track days with a very wet drive cross country the day before a track day which was ok, although i could feel a massive loss in traction crossing white lines on the motorway, and the morning before a track day driving through wet cool lanes which required a huge amount of care and attention not to end up in a hedge.
