“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.”

Tire A

Continental ContiSportContact 5

We haven't collected enough community discussion about this tire yet.

Tire B

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.

“I've got a similar issue with my rear-left having nearly 0.9 mm less central tread than the others, all at same pressure from cold. Suspect it's just due to the way sunlight falls on the car where I park it, warming up that corner over time just enough to raise its pressure before every trip. Either that or a quality issue with the manufacturer custom-made T0 from Michelin (Primacy 3 in my case).”

“Currently riding on Michelin Primacy 3 ZP run flats that originally came with the car. Have approximately 15k miles on it and Mercedes are already recommending I purchase new rear tires. What other options would you recommend as replacements? I would like all season tires that last much longer but also don't want to compromise the comfort and ride. Front tire: 245/40 R19 Rear tire: 275/35 R19”

“As Slacktide said Primacy 3 is a grand touring summer tire that has been replaced by the Primacy 4 (some three years ago).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Sport 2 (PS2) has been a great ultra high performance tire some 15 years ago and I had these at that time, but it has been replaced by the PS3, PS4 and the even sportier Pilot SuperSport (PSS) and PS4S.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.”

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.

Handling is the exception: road tests measure it inside the dry and wet scores, so its own row comes from owner ratings only and starts as less important.
