“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.

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.
“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”
“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.”
“So I have decided there is no way I am paying for the Bridgestone Ecopias at over £200 a tyre, and as such, I have come across the Michelin Primacy 3 on Costco, which I can get fitted for approx £93 a tyre (I only need two on the rear) They seem to have good reviews. My actual tyre size for my i3S should be 195/50 R20, but getting 195/55 R20 instead should only add up to another inch or so in height, so I'm reckoning I should be okay. What are people's thoughts?”

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.
