Second season on the tires. Just finished a longer driving session of 3500km. The tires continue to be sublime on our heavy car. Great stability, handling, roadfeel. In higher speeds the tires feel even better (like 140km/h and above). Also driving in rain feels very confident, even if a lot of water on the road. Comfort and noiselevels are good, despite the low profile. Very low tracking behaviour on less good roads even if front wheels are running 245/40/20.

As a daily driver (Alpina 3 BiTurbo) the 4s (non run flats) get thumbs up in wet and dry for traction, cornering and braking. No complaints on fuel economy considering they're 245f & 265r but can be noisy on poor surfaces (when I've run them run above 35/36psi in the summer) When sporty driving on the limit into bends they can feel short on turn in feedback but it's probably because they're that planted, biting in and doing whats expected of them without a fuss. Confidence giving in summer and wet winter conditions, no comment for ice/snow conditions :-)

My car came supplied from factory on this current set of Michelin PS4S tyres so I don't have an alternative reference point to compare to other tyres. With that said, I'm delighted with most aspects of these tyres performance. They are grippy in all conditions and totally predictable when they do approach the limits of grip. The one area that has been a disappointment is the noise levels when travelling at motorway speeds, but I think this is more to do with the characteristics of the A Class as it doesn't have much sound deadening in the wheel arches. I see no reason to change from these PS4S' when the time comes to replace them. Speaking of which I'm happy with the wear rate: 4-5mm left on the fronts and 6mm on rears after 9,000 miles.

Have run so many different brands of Premium tyres on a tuned up Golf Hatch producing 500HP and with big brake kit and coilover suspension, and nothing like PS4S is just miles ahead in all aspects. Excellent handling and grip in both dry and wet YET comfort and quiet.

Changed out from Bridgestone S001 to PS4 S, better in every respect.

A perfect tyre, grip no matter what, when it's wet it still feels dry

Just had 4 PS4S fitted and what a difference! It’s transformed the car and even feels like it could be daily’d now. So much quieter, smoother and grippy through bends over the ContiSportContact 5’s I’ve had on since owning. Worth every penny.

Knock out. You get in and it drives like a new car.

If you're thinking of buying some high performance summer tyres just stop looking and buy these, iv had them on my last 3 cars (w204 c63, F80 M3 and now F10 M5) and wouldn't change them for anything. Been 190+ on the autobahn (no drama what so ever!) and even a few laps on the ring, nearly 8000 miles later and i still have 6mm tread, that's on a 700bhp M5!
I LOVE THEM!

I have Skoda Octavia vRS 2019.
Before those tyres i had the original one ( Pirelli P zero).
Those tyres was so much better, the feedback is amazing and the grip is perfect !
But i have to say that after 3 track days and 10K kilometers the tyers are dead !

Let me mention my 2018 SL63 came with Continental conti sport contact 5p, and I found them all around an OK tire, but they wore out in 15,000 km... So I went seeking a better tire, I dont care about wear that much, I spent a lot of money on my car and good or the BEST tires are a must regardless of whether they last 10k or 50k, I saw a lot of good and even excellent ratings for the michelin 4s tire, its new and has some new compound in the rubber that is supposed to give better grip.. I have a powerful car with lots of torque, 668 lb lbs, so when I give it I want grip.. I put them on the rear once the Contis were done... These 4s tires when I first installed them on the rear, I found the grip they gave was incredible ! I was so happy, I could finally launch my car properly, but now with 8000 km on them (5000 miles) they are not gripping nearly as well, I would say they are now worse than the conti 5p.. I have lots of tread left, but for some reason they only grip well on NEW pavement. Anything else other than NEW pavement and I can put my car sideways in 3rd gear with my traction control off, and 3rd gear goes up to 100 mph so that is very scary. I have to say I am disappointed the performance of these tires has diminished so very quickly, and since they have lots of tread left I find that I am going to have to replace them already. They are also a bit soft in corners... Thinking of the Continental 5p again, or perhaps the continental extreme contact. Sport cup 2 perhaps???? I just know I will not buy the 4s again.

I thought these tires gripped enormously when I first got them but after 8000 km they are not gripping nearly as well and yet have shown little wear. They are wearing far better than the conti 5p my car came with, but the 4S seem to be very very slippery on certain types of road pavement, if its a bit of a light grey very smooth pavement with a bit of a shiny look, the tires feel like you are on ice and will cause the car to loose traction even under light acceleration. Im not sure if its the rubber compound, but I think i will try another type of tire next time and compare on the same roads to see if I can duplicate these slippery conditions.
