“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.”

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.

“Is your tire size 235/55-18? You might like the Michelin Primacy 3 which is actually a good price for an 18" Michelin. They are summer tires, but that's OK if you have separate winter tires. The Goodyear Assurance Maxlife sounds like something that will last a long time. The Cooper Enduramax is good if you drive over potholes and curbs because it's supposed to be tougher”

“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.”

“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?”

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.
