Bridgestone Ecopia EP422 Plus 

I've only had my car for a month or so, but I recently took it on a long trip of 900+ miles and it was pouring rain the entire time. I have to say that I was incredibly impressed how well this tire was in the rain! This tire performed better (absolutely ZERO hydroplaning)than the Bridgestone tires I have on my other car that were specifically made for rainy conditions and this is a much lighter weight car too. I will write another review when I have more mileage on them, but so far, I'm extremely impressed. Yes, the tire is low-profile (so not much cushion there) but it handles like a dream! Yes, the tire is noisy (common with this type of performance tire) but not overly so. Yes, there is a little bit of slippage on dry pavement.... but that is exactly what makes this car/ tire combo so much fun. Perfect for the "drift" ;-)

OEM tire on BRZ. I race BRZ in 86 cup. Never liked the OEM tire, but last time when it was raining. I had no choice to use this tire. (The other set is NT01 R compond that already down to slick.) Mid range rain, many water puddle on track. No hydroplaning at all. Wet traction is not ideal as RE-71R, but 71R can't protect you from hydroplaning. I tracked this tire on dry before and believe this thing is worse than crap. But it supprised me last weekend. For BRZ owner that track your car on tread wear lower than 200, I would suggest don't throw away the OEM tire.

These tires came on my Subaru BRZ and I was very happy that they did. Knowing that Michelin uses a lot of tire technology that they've developed in world-class sports car racing made me excited to have such a tire on my new car. I'd driven around town and on the highway and had been very impressed with the responsiveness of the tire. They give you a great deal of confidence in that they hold to the road very well and won't lose grip until you push them to their limits. Once you back off the grip is right there were it was, they are very consistent in this manner.
However it wasn't until last weekend that I truly understood how good a tire these are. I drove to The Tail of the Dragon on the North Carolina/Tennessee border (if you've never heard of it google it) for some driving adventure. This is where the Primacy tires really showed their potential and how hard they can be driven! They allowed me to dive into sharp as can be turns with great speed, and then exit the turn and get back on the gas immediately. They were again very consistent, I knew when they were going to start losing grip. It really did take some very aggressive driving to get them to their limits though. Another guy in front of me had a BRZ with a turbo and rally-cross super sticky tires. I don't think it was all because of my driving skills that allowed me to keep pace with him, I shouldn't have been able to, he had a huge advantage on me. But again, I was able to get back on the power immediately upon exit. I'm tempted now to try their Pilot Super Sport tire, but I think I'll get many more miles of enjoyment out of the Primacy. Seeing as how these are a summer tire I'll probably switch over to the Pilot Sport AS/3 once the temperatures drop, but until then I'll be tearing up the roads on these Primacy tires! Well done Michelin, well done!

Although Renault are known for their great handling, only a good tire will make this come alive. I've had my Primacy HP on my Megane Hatch 08 for over 61,000 km (38,000 miles) now, and despite my aggressive driving style, they're still in a very good condition, even according to the dealer! great grip, ware-rate and handling.

A lot of people are complaining about the Primacy HP because they lack ultimate grip in the dry and do poorly in the wet.
I think this is a fantastic tire for DD and a tire that can teach you how to drive well.
The tire has just the right amount of grip in the dry so it is not difficult to slide. At the limit, the tire communicates well with the driver both audibly and through the steering wheel. The tread life is insane, I ran two intense track days, the tread was only down for 0.15mm, meaning you can get 30 track days out of them until they get to 4/32 of tread depth.

Pros:
Good Turn-in
Predictable and communicate well with the driver
Wore like an iron
Nice Companion with tail-happy BRZ

Cons:
Lackluster wet performance
Lack of ultimate grip in the dry
a touch noisy on the street

I selected this tire because of previous experience on another car. I found that the tire has proved itself in all areas to be even better than I expected on this car with sport suspension. The ride, handling, lack of road noise, and comfort are above my expectations. Tread life at this point is great.
I would recommend this tire, and will use it again.

A good looking tire. The comfort is what I expect from a low profile tire and the performance is above par on dry hard surfaces. A perfect tire for a daily driver and occasional fun driving on twisting roads.

OEM tire on my BRZ. They are not terrible tires. In the dry, the grip is good enough for all street/hwy driving. They are stable in corners, breakaway is predictable there's able audible warning - tires start to chirp/squeal when pushed. Sidewall is pretty flexible, so ride comfort is decent, but steering response is a bit slow.
In the wet the grip is only average (and that's in a sporty coupe, that can extract more grip out of these). So I suspect that in a regular sedan wet grip would be below average. Breakaway is much more sudden, although that's normal for most tires. Don't think I've hydroplaned on these while they were new, and I've stopped driving in the wet, so I don't know how these behave when worn.
All in all - a decent summer street/hwy tire for a second (rwd) car that doesn't have to be driven in wet weather, good for someone who's not a grip junkie and likes to slip the rear end around a corner from time to time.
On the track/autox they are fun and communicative, but get greasy quickly and wear the shoulders much too quickly.

I replaced the OEM Goodyears on my Infiniti M35 with these. The difference was night and day. Having the M35x with all wheel drive, I was able to slide sideways around corners with the stock tires on wet pavement. Of course, that's occasionally fun and when I tried to do the same with the Primacy, I found I couldn't break free, even in the wet. I've put around 15,000 miles on the Primacy in a 4500lb car and I've got no noticeable wear on them. My driving varies between economy driving (I make a game of not using the brakes) and 110mph runs in the boonies and hard cornering on the ramps and the tires seem indestructible. I bought used, but my stock tires were done after 25,000 miles.



Best tires I've ever owned.

For what the tire is made for, which is a summer touring tire for a 4 door car, it would be a good tire. To be included on a 2 door sport coupe is a little disappointing. The tires do well just cruising down the freeway, not overly noisy, not overly rough and track nice and straight. They also resist hydroplaning relatively well and haven't given me any issues.

however cornering ability leaves a lot to be desired, the tire gets greasy and likes to slide out. they also get very audible when being pushed and the tires tend to stay cold even when pushed so when the temperatures go down, they never heat up and stay very slick. Wet cornering/traction is just bad, like real bad, again because the tires just don't heat up they offer little to no grip when wet out and you're left driving like you got miss daisy in the back.

Treadwear is fantastic. I've put on 12000 miles and the tires look hardly used which is impressive. If i had a 4 door family hauler that needed summer tires that got me good MPG i'd get these for sure. but for my car they're pretty useless and i'll be looking to replace them with something sticky like the pilot super sports (which are a cheaper tire yet 10000x better).

Changed from Dunplo Sport SP6060 to these after 50000km, I noticed a big improvement in handling and noise levels even fuel economy! Great tire over all. Even the tread wear on the new michelins is much better than I expected, 20000km and still have 50% tread left.
