In January 2020 I did get a new Focus ST Line (182 BHP) fitted OEM with these tires. For some reason Ford has switched from Pilot Sport3 to Primacy4 on all new ST-Lines with 18" rims. I know the PS3's very well from my 2 Peugeot's 308 GT's I had before the Focus. Perfect tires with the only disadvantage they wear faster. But back to the Primacy4. From start on I had vibrations on all conditions at nearly all speed (tires cold and warm, warm lesser vibrations but still there). The wheels where balanced and the car drove straight perfectly, so that could not be the reason. After approx. 3000 miles the garage switched under garanty the tires to Continental PreniumContact6. The difference could be feld immediately, apart from a little more road noise with the Conti's and a little bit less feedback, esp. turn in, the Conti's where much more comfortablee (no vibrations) and much more grip also (inner wheel didn't slip anymore in same conditions). I think that the combination of hard wheel suspension bushes of the Focus im combination with the longtidunal laminated profile of the Primacy4 its results in more vibrations, the reason why none of the Focusses I did testdrive (they had all PS3) had the same problem. I did testdrive a Peugeot 208 II with 16 inch rims and this car had also the same vibrations but lesser due to a more comfortable suspension set up. For me never again Primacy4 tires.

F30 BMW 320D on standard factory fitted Bridgestone runflats on potholed concrete Bangkok roads was enough to shake fillings loose and they had to go. Fitted Michellin Primacy 4 and as they say the difference was like night and day. I can now drive on streets I have steadfastly avoided in the past and the expressway ride feels like air suspension in comparison. Wouldn't hesitate to recommend Michellin Primacy 4

I'm using 205/55/16 in my Honda BR-V. I live in Jakarta, Indonesia with not too good asphalt quality. I used it for my daily activity to the office. My office located about 12 kms from my house. In high speed, it feels great plenty of grip either in dry condition or wet condition. Cornering also feels great. I can easily control my car. The factory tire is a Bridgestone Ecopia. Compared with previous tire, Michelin Primacy 4 have a lot better noise. Honda is well known for bad road noise specially from tire. But with Michelin Primacy 4, it can be minimalized. You still can hear some noise but a lot better than the factory tire. After using about 10.000 kms, the tire still feel great.

I have not had one problem with my Michelin Primacy4 tires. I do not drive fast but I don't hand around either. the roads I use are a good mix of motorway, main and side roads. The tires are very comfortable with no real noticeable road noise. They are lasting extremely well and I will have no hesitation in buying them again when the time comes.

Superb Tire in wet and dry conditions. Virtually no road noise . I really trust these tires as they grip so well

I purchased a set of 4 of Primacy 4 tires approx. 4 weeks ago after being told the Primacy LC were not available.
After having 8 sets of Primacy LC these tires are a very hard compound compared to the Primacy LC and the amount of noise and thumping of the suspension over bump strips,expansion gaps on bridges and general road pot holes is beyond belief. I now have rattles in the car and suspension that I have never had before. Adjusting tire pressures has made no difference and when the tires are cold the problem is worse. The tread is far to hard and is not compliant and has been developed for wear and not handling. Braking is very good on dry roads but only average on wet roads and it is very easy to spin the front wheels on acceleration from traffic lights on damp bitumen.
The smoothness of the Primacy LC's on the same roads has gone, along with the road holding when pushing into corners at speed and I am using a lot more fuel compared to when the Primacy LC's were fitted.
my regular commute to work is approx.350 kms per week on the open road and I was getting 400km per half tank.
This has now dropped back to between 310km & 350 km since fitting the Primacy 4.
These tires are overpriced and ride very harshly and do not inspire confidence in corners and there must be better buys.
I have only done 2000km on them so far so I cannot judge what the wear rate will but as that a very hard tire know doubt it quite high.

Quite a decent tire nothing much to complain about grips really well driven around 10k km and there is almost no wear at all ! Pretty happy with them

Wanted the Primacy 3's again. 20k out of those and was happy. currently 21k out of these, after tire swaps front to back at 14k. currently 5mm front and rear. Its November and really want to change to winter tires, but can't see the point as there is too much left on these tires after 10 months of use.

They don't keep pressure too well. tend to lose 2 to 3 psi all round in a month. obviously they get softer and comfort kicks in before steering gets heavier.

straight line traction is OK in acceleration. braking is a different matter. these are the only tires that have caused me wheel shake on baking hard. (disks and pads changed for the same reason, but the effect is still due to the tires at 38 or 36 psi both sides.

These tires are really a mixed bag. While dry and wet braking, wet handling and cornering are good, straight line traction off the line isn't. You have to know I drive a car with just around 120 BHP, which is nothing really. I get too much wheel spin on tarmac off the line and even mid 2nd gear which is really weird. It is like these were designed for rear wheel drive cars, whose tires will not spin as much off the line compared to a front wheel drive like mine. Wear and comfort are good so far, no worries here at least.

Overall while I wanted to like these tires I wouldn't buy them again really.

Hello from Greece!
I bought this tires before 1 month. Its a premium touring summer tires very smooth and quiet BUT its not for racing driving so much.
They have soft soft soft side walls so its not for extreme corners like the tires i had before, Continental sport contact 2 and Dunlop sport Maxx RT and the Pilot Sport 3.
So i am not so satisfied beacuse i want more sporty tires but it is a good tires with good braking distance and dry handling. In water i cant say something beacuse in Greece we dont have raining already wet.
Thanks.

To me aquaplaning is the main issue especially when u r driving near to the side of the road where water tends to accumulate more. The tires felt lifted when going over a puddle of water.

Having owned these for 2 years now I wouldnt buy again. V hard compound which might give great wear and maybe ok for motorway use but is at compromise of most other things.

Pros:
- Good wear.
- Wet braking/handling

Cons:
- Hard compound means skiddy on gravel surfaces.
- Hard compound means seal on older alloys to be poor and loses tire pressure easily.....I assume less easy to mould/seal on alloys.
- Hard compound doesnt make for v comfortable ride/bumps/potholes.
- Virtually no feedback when driving so makes handling difficult
