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.

Original equipment quality: optimum adjustment to the vehicle
Tyres with a special OEM marking on the sidewall, e.g. "MO" for Mercedes-Benz, were developed in cooperation with a specific car manufacturer and the tyre industry. These tyres have been homologated by the vehicle manufacturer and are a perfect match for a specific model. They have been specially designed to highlight or further improve the performance characteristics of the car in question, thus representing the culmination of a state-of-the-art fine-tuning process that perfectly complements the latest technological developments in the automotive industry. Tyres with manufacturer's markings can of course also be used on other vehicles.

Overall good tyres, sidewall is a bit too flexy and it gives very vague steering feel. The rubber is resistant to wear and can handle repeated hot laps up to 5-10 then they start to lose grip. Quite fun tyre and very safe for normal road driving.
24.06.2024fromAndrei Jescu
Verry good tyres , nice grip on wet roads , on mud , any test has pass done and easy , so happy with it and will buy soon again

Great tyres , good all round grip, as I live in Scotland the seasons change every 5mins, with plenty of rain &amp; the odd bit of snow , I do some off road driving and never got the car stuck, I do run this type of tyre all year round , but as the car is quite light I always change my tyres when they get down to 3mm , I think this is far safer ,
01.04.2024fromRobert
The tyres perform unbelievably well. Braking and grip in the wet is just phenomenal. Outstanding performance. Superb and consistent grip in heavy persistent rain along French motorway to the UK, long and short journeys.
16.05.2023fromRacer 1974
I went for the BMW approved (star marked) Blizzak and I&rsquo;m very happy with the tyres. I&rsquo;ve had Conti Winter Contact on previous cars and in regular use I would say the Blizzak is very comparable. The car retains decent steering feel and traction on wet and dry roads plus offers a far greater level of grip on snow/slush over a regular tyre. Ride comfort seems pretty much unchanged, as always with winters there is a little more noise but it&rsquo;s slight and after 5 minutes you don&rsquo;t notice! Fuel consumption does increase very slightly over the summer tyres BUT that could be down to the cold weather as much as the tyres!
11.05.2023fromSam Summers
I bought these so that I wouldn&#39;t have any mishaps during the winter in my beloved car. I was worried that it would be a nightmare to drive in the snow due to being rear wheel drive and its power. I put these tyres on the front and different winter tyres on the rear and never had any problems at all - very surprised and impressed!

My size tire was not available on the site, it&#39;s 21&quot; and not 18&quot;. My experience is maybe unique to Tesla cars, but it has only 1-2mm left after 17000 km. With Hankook and Pirelli, I&#39;ve gotten better milage... The tire can suddenly lose grip in aqua planing conditions, which I did experience once on the highway - and not with any other tire. But maybe all tires would have this issue under the same conditions. My main issue is that the tire wears our very quickly especially on the rim area, making tires wear out prematurely and they easily puncture if not detected (can see white threads, but not visible easily if on the inner rim). Some of this is likely due to Tesla ABS system activating easily in sharp curves, as I have not experienced these issues with other car brands. Both model 3 and model S have this issue. These tires I need to replace quicker than 17000 km as one of tires has just approx 1mm thread.
07.06.2024fromMalcolm McKay
I chose the Pilot Sport 5s for my car for 6000 miles of arduous driving, leading a classic car rally around all of Greece. We were heavily laden and driving hard on very mixed surfaces. The Pilot Sports never let us down and showed impressive grip throughout. Even better, 10,000km later they have worn remarkably little, and very evenly. The sister car was on Toyos which admittedly are cheaper, but showed a LOT more wear.
22.08.2022fromJustin
Size = 255/40/19. I had the Pilot sport 4 on the front, went for the PS5 on the back as they were just available and they were great. I would definitely go for them again but I just changed my car and it looks like Michelin do not support the new size tyres (305/30/ZR21) but I will keep checking Michelin.

18.04.2026fromJ Lynch
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.
15.02.2024fromDavid 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.
09.02.2023fromJohn Molloy
These tyres are noticeable quieter than my previous tyres, Kumho Exta. Cornering grip is better and fuel consumption is slightly better
09.12.2021fromNicholas
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.

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.
