“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.”

Michelin Primacy 3
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.”

“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'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).”

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.
