“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.”

Higher is better. The Relative Score follows your weights below; category scores do not change.
Wet grip starts at “Important”. Treadwear starts at “Neutral” here: road tests measured it for at most one of the two tires, so it rests on owner reviews. Move the sliders and the scores update instantly.

Themes extracted from owner reviews found online — not the opinion of TireWheelGuide.
From Reddit, forums and review threads. Not part of our score
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.
“By far the biggest determinant in road noise will be the road surface, as you found, and no tire will overcome that basic fact. That is so obvious in my area where there are new sections of highway interspersed with old sections. Having said that, I'm running the older Michelin Primacy 3 ST tires on 17 inch wheels on my 2021 ES300h and they are great, compared to the Turanza I was running on 19 inch wheels on the same car. The Michelin Primacy Tour A/S should be even better in this regard. Not sure, but perhaps the higher profile of the 17 inch tires (215/55R17 vs 235/40R19) also helps reduce road noise.”
“I have Pirellis on my 2014 F31 wagon. I have overinflated them slightly (3 psi front, 2 psi rear) because with the pressures placarded on the door post they are not responsive enough. With the overinflation they make fine street tires . At the limit they are still a bit soft, but the limits are so high that I have no business driving like that on the public highway. Tire Rack, I believe, tested Michelin Primacy 3 ZP (zero pressure, or run-flat all season tires ) and liked them. I have no thoughts about Continentals , so that I am only muddying your waters by adding in the Michelins for consideration.”
“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”

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.
