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.

Good grip, solid performance on rough country roads, and smooth enough on A roads, balanced breaking and no vehicle shudder
05.02.2025 from Dean
I've done around 8500 miles so far in mostly poor weather , very good grip in all winter conditions and mild conditions. Good all rounder.
28.05.2024 from Marcis
Good grip on wet and dry roads. Reasonable grip on snow and icy roads. Noisy on dry roads. Fuel consumption has increased. All in all decent tyres.
07.04.2024 from Harry
Incredibly capable tyre for all conditions, but my experience on the roads in West Yorkshire will probably dictate that I don't purchase these tyres again as they are too soft on the sidewall, they do need some sort of protective band. The roads a terrible around Haworth for potholes, and in this case I could not dodge one and it has ripped the sidewall and damaged the rim, rendering the tyre scrap.

Car Driven : BMW 425D 225Hp . Quite quietly from the start until the first 10,000 km they kept a relatively low noise level until the end of their lives. Relatively comfortable especially considering that is a runflat tire. The tire tread still retains its original groove and design but has significant wear points on both edge and there are some small tire detachments. In the few rains we have in Greece it never had a hadling problem or breaking and did not create any feeling of insecurity. in short it is a good quiet tire ROF tire, comfortable and efficient in fast driving.
31.12.2021 from Stuart
Big improvement on the OEM fitted brand. More refined, quieter and more confident grip in both wet and dry. Fitted full set; 215/45R17 in front and 245/40R17 in rear, as standard spec. Only driven on road (A and B roads and some motorway), no tracking. Hard to fault for this purpose.
16.07.2021 from Rok Sharma
I drive fast and furious when required or slow and deliberate in slow traffic! I used these tyres on my 5 series BMW 525iSE and were superb! Now on Mrs Peugeot 308 hdi and pretty good!

Good tyres but not as good as the Michelin pilot sport 4. Will be going back to the sports.
04.12.2019 from Ali
I am a High mileage driver covering all roads day and night. This is a premium summer tyre made for dry grip and wet braking. Out of a budget , midrange and premium I’ve noted , the cheapest gives me around 6000 miles. The mid ranges cover around 12000 miles and premiums last around 18000 miles. In terms of grip it always has to be premium. These are also much quieter than budget tyres. I’ve covered 25000 miles of hard driving with these tyres and they still have around 3mm left. This is the second summer I’ve purchased these tyres. Good on price as well as grip

18.12.2025 from Keith
Unlike some who write stuff thinking they'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

16.08.2024 from Jan Olsen
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.
07.06.2024 from Malcolm 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.
22.08.2022 from Justin
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.

These tyres in my rear wheel drive BMW are grippy in the dry, but leave me yearning for more in the wet. The car will "step-out" if I punch it whilst the road is even midly damp. My tracking was done at the same time as having these fitted so that is not a factor. The car will also step out if the road is more greasy looking.

29.05.2022 from Jamie Hewison
Bought these tyres as a bit of an emergency stop gap after somebody had slashed my tyres in a city centre car park, they were only supposed to be on for a few weeks until pay day and I could afford something better, however they’ve now been on for 6 months and have been used in all weathers, including a couple of muddy tracks. They perform really quite well, grip is very good in the dry, only a slight decrease on wet roads and better than expected in the snow. Although they’re not a mud tyre, they still handled the muddy farm tracks with ease. Fuel economy seems pretty much unchanged, road noise is slightly higher than a premium tyre but not so much that it becomes intrusive. Tyre wear is on par with others, I’ve done 10,000 miles so far and judging by the remaining tread, If I run them all the way down to 1.6mm, I think I’ll be on course for a 20,000 mile lifespan.
