I use 215/40/17 87Y Michelin PS4s in my 2013 Ibiza CUPRA vehicle in the summer season, high performance summer tire for the summer heat on the Mediterranean coastline in the South of Turkey, it provides very safe handling even at high speeds on dry or heavy rainy roads, very safe after the tires are warmed up. it grips well, grips the road well, very fast and superior grip steering response on mountainous and tight curvy roads between cities, super slip on the panic brake on the dry city road when cold, ABS is activated very often, but I think the reason is because it is a low profile sporty tire with 40 sidewalls, about 25,000 since 2017 as a summer set of them. I use mileage, I have a separate set of tires for winter. I think that MICHELIN does not produce summer tires as long-lasting as winter tires, unfortunately PS4s were subject to rapid deformation despite low mileage and became old. I will replace them with ASYM 6s in the summer of 2023.

I've been running PS4 tyres for a number of years now after giving up on the likes of Bridgestone and Yokohama, mostly because not only are the inferior in grip and handling, but also don't seem to last all that long. I had a Ford Falcon G6E Turbo with around 400rwhp for many years and the PS4's were great. I still only got 20,000 to 25,000km out of them, but that was still better than the RE003's I'd had on previously, which never made 20,000km before reaching the wear markers, and they are in a different league than the RE003's especially in the wet - and we get a lot of wet where I live. Wet breaking is insane, almost supernatural.
Sadly the Falcon got written off when another driver decided to rear end it, and I'm now driving a Lexus GS460 - I replaced the crappy eco tyres that were on it when I got it with a set of PS4's - same size as I had on the Falcon, and the Lexus is a similar weight, though a bit less power, not entirely dissimilar suspension design though probably a bit more sophisticated than the Aussie boat. That was 7,000km ago - and I can tell already the Lexus is not going to be anywhere near as hard on tyres as the Falcon was.
Anyway the PS4's are obsolete now, as the PS5 has just replaced them this year. I'll be trying those out eventually, but it does appear the PS4's I have currently are going to last a lot longer than they did on the Falcon - at 7000km they still have over 5mm front and close to 4mm rear, so after a rotation I'll probably get another 20,000km out of them at least.
All in all, if you can still pick up a set of PS4's, and you drive a heavish, powerful RWD saloon with multli-link double-wishbone suspension in a subtropical climate, the PS4's will probably suit you well as they have me.

Great tyres overall, perfect for daily driven performance vehicles

Excellent grip in wet and dry. Wear is just insane! In this size 245/40/18, I have done 47000Km so far and there is about 4.5mm of tread left! Due to the staggered wheel design on my car, these are on the front and have never been rotated in 5 years. I must admit, I never abuse the tyres. The story is much different for the rears. Size 265/35/18 and the tyres are finished after 33000Km (4 years) - 1.5mm of tread left. So, same tyre model but different size and the wear rate is drastically different!

I had the tire for 65,000 km and during that time I was very pleased. At first the grip was great during wet and dry conditions and the noise was not very much. After about 45,000 km grip started to fall and after 60,000 km there was a humming noise from the front tires, and there was a pretty big drop of performance from the front tires creating lots of understeer (admittedly I never switched front to back so that had something to do with it).

In short I'm very disappointed with these tyres as they don't provide a "sporty" drive feeling. Negative: - They don't provide any feel or feedback while cornering which is probably related to the second point. - The ride feels very harsh and unforgiving. - Wet traction is very bad, a lot of wheelspin in the wet. - Cornering grip becomes dangerously low at lower temperatures / below 12°C. - They tend to understeer in all conditions. Neutral: - The rolling noise is acceptable, no high-pitched noise but a heavy rumble can be heard. Positive: - Rolling resistance seem very low according to lower fuel consumption than previous tyres. - The tyre wear appears to be quite good. I haven't tested these tyres on the track and I'm assuming they can provide better grip when they're heated up. This seems to be a very hard rubber compound.

Bought to replace partly worn Goodyear Asym 5s which had been on the car prior to my ownership and on which I covered approximately 5000 miles. The MPS4s have also covered about 5000 miles in my hands and the difference was night and day. The key feature is an incredible amount of grip, most notably in the wet. Shortly after fitting these tyres I relocated to the north of Scotland, where they performed adequately through the winter, tackling snow and ice with better results than I had expected. Comfort is not the best, I must admit. There is a considerable amount of tyre roar and the tyres do not absorb road imperfections with much grace, but these are not touring tyres and I suppose that's the nature of the beast. Fuel economy is remarkably good though, returning an average of 47mpg on mixed town and country roads with an inefficient automatic diesel. After 7000 miles of use, the tyres are down to a shade over 4mm on the front and about 6mm on the rear with very little loss of performance. They also hold air remarkably well, for what it's worth. Definitely one of the best tyres out there in my opinion for a medium performance car.

I replaced the OE Continental SportContact5 on my 2020 Kia Stinger GT-Line with 19" staggered wheels because they were worn out in less than two years and provided no traction anymore. I replaced them a year ago with the Michelin Pilot Sport 4 tyres, and while I felt the sidewalls of the front tyres were a bit softer than the Continentals, everything else was much better. I can make hard, and sudden lane changes at 200+ km/h while feeling confident with the Pilot Sport 4.

An overall excellent tyre. Outstanding grip wet or dry. Since having PS4's fitted I've never been concerned with losing control of the car or if the car will do something unpredictable no matter the weather. However, below 4°C they do turn to bricks and it's quite noticeable, but they're a summer UHP tyre not a winter or all-season tyre. Braking is excellent with the ABS only kicking in under 35mph in the very unscientific test I did, cornering feels pretty good but you notice the tyre needing to be loaded up first before it properly bites which is especially apparent in chicanes but this only takes a second and can easily be accounted for. I had to really try to get the tyres to break traction pulling away in the dry which would only result in a small chirp and I could only get the tyres to spin in 1st and 2nd in the wet putting my foot to the floor. Coming from a mix of Accelera's (front) and Bridgestone's (rear) I have complete confidence in the car and have never been able to upset it and have ESC kick in. A number of times with the Accelera's I had the car understeer in the wet with ESC kicking in. On one particular occasion having the car go straight on at a roundabout doing only 28mph, reducing my steering input and braking did nothing it was luck and having a car with ESC that made it turn. On another occasion having the front wash wide on some back roads at a corner I'd taken at the same speed in another, much older Polo with Yokohama V701s fitted in a smaller size (195) and no fancy ESC and traction control systems perfectly fine. After those experiences, I ordered a set of PS4's within 2 weeks of getting the car and I now firmly believe that you get what you pay for with tyres and there's no point in getting something that is "as good as but". One thing to note is that after fitting a set of PS4's my MPG dropped from 44-46mpg to 39-42mpg on average. But I didn't buy them for their fuel economy and expected it to drop. On the odd occasion that I've been caught out by a corner being tighter than it seemed the tyre told me that it was at its limit but never let go and was very easy to predict and manage. Bumps and potholes can be felt more compared to the previous tyres that were fitted and road noise is quieter comparatively but in general, is still fairly loud. However, I believe that's just the car. It's a Polo, not an S-class Merc. The tyres came with around 7.5-8mm of tread and I'm now down to 3mm on the lowest tyre after 22,000 miles roughly of motorway, normal day-to-day use and spirited back road driving with no perceivable loss of performance wet and dry. I would buy the tyre again but newer tyres have been released which perform better. As Michelin dropped the 215/40/17 size from the PS5 I'll be getting a set of Goodyear Asym 6's to replace the PS4's in the coming months. Hopefully someone found this useful :)

Feel and handing and grip and steering precision very much improved on my previous tyres(primacy 4) fuel consumption much higher - more than 10%- but I wouldn't change back as the general handling ability has changed the entire driving experience

These have lasted 15,000 miles and were fitted to the front of my BMW 520d M Sport (runflat) and still had 6mm Excellent dry and wet grip Treadwear rating 320 AA I sold my vehicle but I think they would have done at least 50,000 miles

Had these fitted on my R32 replacing the poor budget tires previously on it. Impressions were great, suited the car very well. Best wet performance of any tire I've driven, dry performance not as impressive but very good, has a tendency to understeer. Quite noisy but to be expected.
