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

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’t praise enough.

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'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've ever experienced on a car, I had used continentals and dunlop's beforehand, 2 competitors to Michelin, and before now, I always struggled with understeer under sharp cornering after periods of rain, with the PS4'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.

My size tire was not available on the site, it's 21" and not 18". My experience is maybe unique to Tesla cars, but it has only 1-2mm left after 17000 km. With Hankook and Pirelli, I'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.

I bought these tyres as wanted a budget sport tyre for our recently purchased vauxhall Insignia, so got a pair from Oponeo. They sent Sport 2's which are a Chinese made model. Have been generally happy with these as been on some long & many short trips in last year. They have given confidence inspiring performance through all weathers & never given me reason to regret buying them. They wear well too as still lots of tread left. Recommended...
23.08.2022fromCallam
Good grip on a dry warm day , Starts excessive oversteer in the wet, and they are almost down to the treadwear indicator in just under 3 k miles . Easily looses traction under acceleration in the wet

Fabulous tyres and exceptional wear, considering the price point of these, especially given my driving style. I'll definitely see over 20000 miles on these tyres which I find remarkable on a heavy car with over 400hp. Could I have better grip, sure for twice the price. Do you really need it, even for having fun on UK roads, no! They are soft rubber though, so you'll know if your alignment is out, these didn't last long on my Merc V Class!
08.08.2020fromDean
Doing relatively high mileage of over 40k every year, I've been through various different premium tyres over the years. Let me tell you, in the 5k miles on these tyres so far I'd say they're pound for pound up there with premium tyres for everyday driving. I've found them to be really good in the wet, no major drama with aquaplaning and my heavy right foot has encountered no issues in cornering. Strangely, I've found that I'm more confident with these in the wet than dry- they tend to be slightly unpredictable when pushing on. Not a massive issue by any means and shouldn't put anybody off, it's just highlighted by my spirited driving style! Wear seems to be decent so far, but as I said I've only done 5k so far so too early to tell. All in all, great value for money and worth a try. On 20's, The Goodyear Eagle F1s that I had on previously were £160 each, whereas I got these for £115. 200 quid saved, and genuinely no worse performance. Well done Viking!

The car feels very safe cornering and braking is very good , it drives straight no wandering overall I’m very satisfied with the set of Tyres.
