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.

18.04.2025 from Rafał
I had them on the front from new, after 2000 miles they start generating more noise ,after 10000 miles (1 year) depth tread was 2mm. Never buy any cheap tyres again .
23.02.2025 from Ricardo Rodrigues
Good grip on dry and wet , the noise is not bad but only lasted 10k miles. All uniform wear but only lasted 10k with very smooth driving
25.11.2024 from Liam Denning
I’ve tried to push these tyres to the limit and they hold up really well. Great performance overall, doing as well as the premium priced Continentals they replaced. Well impressed!
22.08.2024 from Kevin Broderick
Really good tyres. Bought on the mechanics recommendation and I’m delighted I did. Just as good as the Michelins they replaced. Excellent grip on wet roads even at high speed.

29.05.2025 from Jerry
I began using these tires last winter and drove them all over Europe, on both dry and snow-covered roads, including motorways and countryside routes. So far, I have driven approximately 7,000 km on them and have not encountered any issues. They perform reliably on snow, as well as on dry and wet surfaces. The noise level from the tires does not seem to be louder than that of other tires, although this may vary depending on the type of car you drive and its level of quietness. Additionally, the price was reasonable. Therefore, I will definitely consider purchasing these tires again in the future.
22.03.2025 from Marcin
tires never arrived, money back after a month, I do not recommend
09.03.2025 from Marek
The tyres have good performance, of course the UK speed limit of 113km/h does not allow for a better test of the tyres on wet roads.
27.12.2024 from Ian
Tyres seem fine no problems so far. Have not had a chance to test on snow.

07.12.2025 from Padraic Tierney
so after 14 months/25166 km of driving these tyres are down to 3 or 4mm on the front and 5.5 mm on the back. I've never had any need to brake hard in the wet but i have corned sharply at 90 km/hr using these tyres and they do hold the road well. I know i should rotate these but its hard to get time for everything. They are very good value but maybe a bit noisy on the road. I bought 4 together and at €120 each when you compare to michelin pilot sport is really great value for money. They are wearing fairly evenly too so overall the verdict is i would highly recommend these.

As tyres on rear axle they perform very good, never slipped, not noisy, no vibrations, not worn, perfect for the price, for now I am very happy with the purchase but I have not pushed any tyres to extreme, I am using them as normal driver would mixing countryside, highway and city.

12.12.2025 from DAVID
These tyres are outstanding. The car is a 25th Anniversary GTI with a ported and polished cylinder head and fitted with SACHS Race Engineering coilovers. I require tyres with the highest possible grip, in both wet and dry conditions. For this reason I only fit AUDI AO specification tyres as this specification was developed for the maximum grip on the high performance fwd Audi TT. Which uses the same platform as the MkIV Golf.
18.09.2022 from DAVID
These are as close to perfect summer tyres that I have come across in more than 50+ years of spirited driving. Wet grip is of great importance, and these tyres are actually AO, which I always purchase, as I understand that grip was paramount in AUDIs requirements. The car is a modified 25th Anniversary model and is fitted with SACHS Race Engineering Coil-Over suspension. The cylinder head has been ported and polished with the motor now producing well over 200 ps.

Car had 20" 245/35r20 runflats in front and 275/30r20 runflats (all MOE) for RWD w213 luxury saloon. The car came with these factory fitted MOE runflat tyres. I've Replaced these tyres and wheels at 10600km. I've driven 8600km of that mileage. The tyres wore like rubber bands on the 20" wheels. Steering as a result is very precise in both wet and dry. Front 245/30s have sound deadening foam and overall tyre noise is quiet in the cabin (but just wee bit louder than the 18" PS4 tyres I replaced them with). Ride comfort is 8/10 on highways due to air suspension. On chip seal, speed humps, potholed roads ride comfort is 5/10 - there is very abrupt jarring transmitted to cabin due to tyre profile and rims. Wet grip in cold (5'C) and damp country highways was 7/10 at 110km/h speeds - there was some slip noticeable. Dry grip was 8/10 most of the time but with occasional rear traction slips at highway speeds in curves. This combination of tyres and rims is quite poor for a luxury sedan and compliant rides.
06.06.2020 from Chris Farnell
These tyres are great. Low road noise, and surprisingly grippy in the wet. Like really grippy

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.
