Just buy them. Wet grip is nearly as good as dry grip. Quieter than I thought they would be. The car feels awesome compared with the ditchfinders the previous owner had fitted. I will be fitting these to all of my cars in the future. I've driven my Cayman over 100 miles in the snow with these on and only had one slide which is unbelievable for a tire that offers this sort of dry performance.

This tire is incredible on the road, wet and dry. Taking a turbo-round-a-bout, corner in the wet with 40-50kph is easy. The tire can do more than you sitting in the chair. Wear is for a UHP tire oke, 30000d kilometres and still 3.5mm Noise isnt bad, but can do a lot better. It is no comfort tire I do feel (under the 335d) that with 70-90% throttle, and turning from standing still, the tire is struggling with steadyness on rim. A tyr with rft would not have this I drove before this 4s the Goodyear asy 2 in rft, and they are worde on all accounts

Great performance but after 3000 miles had a split in front sidewall needing a new tire Never had this before in 40 years so obviously 🙄 disappointed

There is nothing I can say in this review which hasn’t already been said. One point will make about Michelin tires which I’ve never seen mentioned (Yes Mr tires reviews I’m looking at you, and your Youtube channel), is that they seem to be able to take a lot more stick than other tires. I drive bumpy country lanes and this accounts for 90% of my mileage. I judge my tires on how safe they make me feel when I’m pushing on round corners etc, this type of driving inevitably results in some pot holes being struck. I’ve not once had a Michelin blow a wall through a bump in the road. The very same roads had completely annihilated several sets conti sport tires which had been factory fitment on my car and 3-4 sets fitted within first couple of years of ownership. Last 9 years I’ve been running the top sport Michelin tires, I get at least double the mileage, no failures and better overall grip, even on cold damp dirty muddy surfaces.

The Michelin Pilot Sport 4S are excellent summer performance tires. They handle spirited driving and acceleration and hold up well in the corners. I am constantly surprised by the minimal wear I find after nearly 20000 miles. Road noise is not the best and the comfort is a bit on the rough side though I would expect as such from a performance oriented tire. That said, grip and confidence in the rain is excellent. I did have occassion to drive around the block in snow ... not a good idea. Snow/Ice + these tires = dangerous ; but again, would not expect differently from a summer performance focused tire. These are a great purchase and, unless Michelin unleashes a Pilot Sport 5, these would be a great choice to buy again.

Runing PS4S on my 380HP/550Nm tuned Golf 6 GTI Edition 35 (FWD). Tons of grip, in all conditions. Much much better then Pirreli P-Zero (OEM fit on 19"), and noticably better then CSC6.

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 tires so I don't have an alternative reference point to compare to other tires. With that said, I'm delighted with most aspects of these tires 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 tires 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 tire, grip no matter what, when it's wet it still feels dry
