“As Slacktide said Primacy 3 is a grand touring summer tire that has been replaced by the Primacy 4 (some three years ago). It's been quite popular in Europe and tire availability/choice in NA/Europe differ greatly. I'd still recommend both Primacy 3 & 4 if you're looking for a smooth riding summer tire. The Pilot Sport 2 (PS2) has been a great ultra high performance tire some 15 years ago and I had these at that time, but it has been replaced by the PS3, PS4 and the even sportier Pilot SuperSport (PSS) and PS4S. If you want something more performance than the Primacy, I'd consider the PS4. I'm currently running the PS4 on my 911 (205 & 245 16 without Porsche spec) and the PSS both on my Cooper (205/45 R17 BMW/Mini spec) and my GTI (225/40 R18 HN spec). So some kind of a 'Michelin fan' too.”

Tire A

Michelin Primacy 3

Mixed

Community members generally view the Michelin Primacy 3 as a quiet, smooth, and capable grand touring tire, with several users highlighting the run-flat (ZP) version as superior in comfort to competing run-flats. However, some drivers report fast tread wear, a harsh ride compared to standard non-run-flat alternatives, and note that the model is older and increasingly replaced by newer generations like the Primacy 4.

“The Primacy3 ZP were installed today. Of course, they need a break-in period, but from some highway and city traffic, I'm already sold that these are the best replacement run-flat tires for our 18" size. The car now glides where it previously "sandpapered" its way down the road with the original harsh and noisy Pirellis. Bumps feel far more isolated. The reviews for DriveGuard have been mediocre, not great. These are far better to my senses. The 225/50-18 size is hard to find. Tire Rack carries the Primacy3 ZP, but not in that size. Another tire store in my area confused them with the non-runflat which Michelin has named the same...just Primacy3. Then, realized they couldn't get the ZP version. Very odd wholesale distribution pattern. Discount Tire was able to order them. First day, but very, very pleased. EDIT: My wife even noticed and she never notices anything about cars. She said the car felt smoother to her as a passenger!”

“Continental DWS06 Plus non-runflats, going on my car next week. Have had OEM Michelin Primacy 3's and they are like driving on bricks. I also ordered an OEM donut spare and jack kit for the trunk. Jack kit goes in lower compartment, spare kept under the horizontal floor net (Coupe).”

“I have just put a new set of Michelin Primacy 3 T0 Acoustics on and they have been faultless. Lots of grip, very quiet etc. They were also good last year in the snow and were from blackcircles for about £240 a tyre.”

How do we compare tires?

Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements), each result compared with every other tire in the same test and newer tests counting more. 40% comes from owner reviews found online, adjusted for how generously each site rates. Both use one scale: the average tested tire gets 70, the best 100. When a tire has only one of the two, the missing half is estimated from the other and the score stays closer to average; with no road test and fewer than five owner reviews it gets no score yet.

Community buzz from Reddit and forums is shown for context only — it never changes the score.
