I just retired my 4x Pilot Sport 4 tyres, as the last two annual car services recommended replacement, with the most recent one stating 10% tread depth remaining (to legal limit). So I swapped them for Pilot Sport 5s on my RWD Benz w213 e300. These tyres were rotated every 10k km, balanced and alignment done. So overall the treadware has been very even. I ran 38 psi on rears and 35 psi on fronts throughout on mostly highway roads.

To be honest the tyres still had tread remaining, and I expect I may have gotten another year and 10k kms out of them till the wear indicators became flush with the tread. The only reason I swapped early is to avoid any insurance liability given the past 2 service recommendations on the car. This is a real shame, as the tires are great at 40k km.

From day 1 they were really smooth and rounded off bumps and edges very smoothly to the cabin. The dry grip was excellent for a heavier 255hp mid torque car. I did feel in the last 10k kms though that sometimes it was giving into barely noticeable slippage on the rears during cornering at highway speeds. But overall the grip was still 9/10 for all intents and purposes till yesterday. Taking off at the lights, it gave me immediate response and always performed it like it was a piece of cake. They never had any hesitation or squealing when I needed sudden bursts of acceleration to overtake all the bumbling rav4s in my neighbourhood.

Wet grip was also amazing till now, it evacuates with a lot of spray out the back and feels planted on the roads at highway speeds. I never felt any aquaplaning on it. I always had immense confidence on these tyres and in my car to drive at the speed limit in the cold wet roads of Melbourne. It may be a different story in tropical climes where you get fat raindrops and torrential rain; but in an English temperate wet climate, these have always performed perfectly.

My sole objective for putting on these tyres initially were to get the most comfort at the highest safety margins which ruled out touring tyres that are comfortable but are not as responsive as these high performance tyres. To this end, it excelled. One time in early summer of their first year, we were up in the mountains when temps suddenly dropped to -3’C and a snowstorm hit. These tyres still drove safely on the accumulating snow for as long as they could and only gave up on an uphill with black ice. These aren’t designed for those cold temps and those tread patterns, so to me they gave me a whole lot more that one time I asked it off them.

Comfort wise, my wife noticed that these PS4 tyres were marginally more floaty and smooth riding compared to my 1 day old PS5 tyres on the highway yesterday. On the other hand, I notice that the PS4s had slightly more noticeable tyre noise coming into the excellently insulated w213 cabin, in comparison to the new PS5 tyres. And I also noticed that tyre noise on these PS4’s had gotten louder in the last 10k km of ownership.

So all in all, the tyres were ageing, but it did everything I needed from them very, very well. That’s probably why I have no regrets swapping them out 10k kms prematurely. They would easily have gone another 10k kms to reach their tread wear indicator, with some accompanying minor performance degradation otherwise, I feel.

Overall I am very happy with the product. It fit my needs and my driving style perfectly.

Fitted to a R56 Cooper S to replace 4x chinese ditch finders that were on the car wen I purchased it. Much much quieter, less crashy, sublime feel and appear equally good in wet and dry conditions. Wear I'm sure will be top notch. I've had 3 x Porsches, S2000 and a couple of MX 5's and this car with these tyres if just fab... I drive it everywhere :-)

It has a quiet and comfortable ride. Moreover, it came right on time. The customer team was very helpful when purchasing.

I've gone through 2 sets for ps4's on my mk8.5 fiesta ST so I've got a pretty good idea of how they feel. These are the OE tires that come with the car and are a good middle ground between performance/wear/comfort. The car is very often driven in a way that would land you in jail in most countries and has seen many mountain roads, highway and high speed cornering. If you want a good all round tire the ps4 will not let you down in any way(apart from them getting too hot quickly) but are in no way shape or form a tire that will extract the most out of your car(sport driving wise). If you have a sporty car which you use for cornering(such as mine) or enjoy pushing it in general just look elsewhere. The car is on Goodyear supersports now and is far superior in the sport characteristics but lacks in the wear department as expected. Lastly it is worth mentioning that both ps4 sets were pretty much done after 10k kilometers.

Notice very bad wear on the inner rear wheels .posted my concern on Facebook and received many responses.some even posted photos of the exact problem I am having with these tyres

Bought the MPS4 to replace the ContiEcoContact that came as OEM, so most the comparison will be done against them, although it's not the same category really... The Michelins will probably wear faster (although I replaced my previous set of tires because of both being used for 40.000 kilometers, and as they started to feel worse in handling - even though they weren't worn out that much), but everything else is much better (aside from stiffness, which seems to be about the same, at least subjectively).

All in all, the MPS4 are great both on dry and wet, they handle very precisely (especially the corners!), and the braking distances are obviously better that with the Conti's Eco tires - literally, like driving a different car. On the weaker side, when hitting bumps (even the smaller road imperfections), they are a bit hard, both in the feel in the car, and on the ear. Also, not very silent on highways, but it's not a big deal.

All in all, a very good tire, that I would recommend, even if it does have a few flaws.

I've been running these for some time now and the rear tyres have finally worn out. For a performance car tyre on a rear wheel drive car, I've been really impressed with the wear rate of these tyres.

Grip in the summer was overall pretty good, my only complaint is that I haven't found them particularly progressive, the transition from grip to slide really quite quickly.

Compared to other tyres I've used, I found these to be quite disappointing in the wet in certain situations. Wet braking and resisting aquaplaning was good, but cornering grip in wet weather was extremely snappy, even at low speed and low revs, just pulling out of a greasy junction.

If you mainly drive in the the summer this is a good tyre but I wouldn't recommend for all weather use.

I had these on my car for 6 years before they started cracking to the point of the tyres losing air. There was still a lot of tread left, but they had to be replaced for safety reasons. The grip was very good in both wet and dry, and they are surprisingly comfortable for what they are, max performance tyres. They're not as grippy as the pilot sport 4s or super sport, which is to be expected, but for strictly street driving, they're hard to fault. I have had various toyo proxes, hankook s1 evo, bridgestone RE040, RE050, goodyear eagle F1, and none of them comes close to the ps4, at least to me. None of them lasted as long, and the michelin ps4 was just better overall.

Comparison Points:
Bridgestone Potenza Sport (OEM)
Falken Azenis FK510

The PS4 is a great allrounder. Having the best handling and grip in the wet from all my previous tires, it is a safe choice. The road feedback and dry handling was better on both my previously installed wheel types. The PS4 is comfortable from a damping perspective, but the tire noise is slightly higher than on both my previously used tire models. The PS4 is the best-wearing tire from the bunch - you can easily get two seasons, if not three out of one set. The downsides on the PS4 are most likely because of a slightly softer tire wall than the previously used tires. Although the PS4 is most likely the best allrounder tire, I'd prefer to get more dry road grip and better feedback from my next tires.

Bought these to replace a set of Dunlop SportMaxx RT and the PS4s were immediately superior in every way. I had them on the FN2 Civic Type R for over 4 years and approx 15,000 miles. They lasted really well IMO and the only reason for change was the PS4s had started cracking due to their age. I’m now on Michelin PS5s for over a year and approx 5k miles and I much prefer the PS4s.
Dry grip was always excellent and was progressive on the limit even during the winter months. Wet grip was also very good and gave me confidence. Noise; I will not say too much as I had the car stripped out for a significant time so my opinion wouldn’t be fair. Road feedback was fine, on the odd occasion I would push it on a corner I could feel how much grip I had and what the tyre was doing. I found the longevity brilliant and after trying out the PS5s I would rather swap the claimed longevity of the new model tyre for what I consider to be better wet and dry grip in the PS4.

Very soft sidewalls make it OK for comfort and crashness, but it feels more like a Grand Touring tyre as it deforms when you really go for Sporty driving.
Combined with the relatively stock suspension of my Ford Focus mk4 1.5 ecoboost, the car needs time to settle when cornering, so driving cannot be aggressive on mid speed sharp corners and therefore the tyre limit is not easy to approach in normal speeds.
The compound itself is of good quality, tyre is quiet and has good handling once it's warmed up a bit (heating up time is very short)
Tyre longevity is a BIG NO-NO. After 15k km the front tyres are half their original tread, even if most km are driven very conservatively.
I have been a fan of Pilot sports until gen2, but I cannot say this for 3 and 4 (non-S), in my opinion these are now GT tyres. Will not buy again.

Just had my 2nd set of Michelin Pilot Sport 4 fitted To my BMW X1 as i was very impressed with outstanding rim protection.
However my new set has 3mm ( 1/4" ) less
rim protection which is very visible, I've emailed Michelin and sent photos of both sets of tyres and requested an explanation
however they have replied to say that they won't reply to my email, i shall choose another brand in future.
