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.

We haven't collected enough community discussion about this tire yet.
Community sentiment towards the Michelin Primacy 4 is generally positive, with drivers frequently praising its quiet ride, comfort, and dependable wet and dry braking performance. Several owners note impressive longevity reaching over 50,000 to 70,000 km, though some EV and SUV drivers report accelerated wear and fragile sidewalls over rough terrain. It is commonly viewed as a premium touring tire that commands high prices compared to competitors.
“Review: Michelin Primacy 4 ST I own a 2023 N8 DCT and recently changed all four tyres from the stock CEATs after one of the tyres’ sidewall was punctured on hitting a rather deep pothole at high speed. Cost: INR 9,750 per tyre Existing tyre buyback: INR 1,000 per tyre (~15k kms) Review: I’ve been using the new tyres for a few weeks now and I’m happy with the upgrade. The difference is noticeable, but only if you pay attention. I’d say a non-savvy person won’t notice anything different unless you ask them to pay attention. At low speeds, the road noise is reduced and the vehicle is noticeably silent (almost dead silent if the roads are smooth and the engine is at low revs) and smoother. At high speeds, the noise level difference is not very noticeable due to the engine and wind noise, but the smoothness and grip is noticeably better. That said, I wouldn’t say the stock tyres are bad (in terms of both - noise and grip) as a lot of reviewers like to point out; definitely not a night and day difference for me. Lastly, I believe the fuel efficiency has improved due to the lower rolling resistance, but I don’t have enough data to claim this confidently. My verdict is to only upgrade if your current tyres are worn out. Personally, I don’t think spending close to 40k is worth it for the budget conscious. But if you have the money to spare, you will definitely be happy with the upgrade. Read more”
“Yokohama es la que va pero fijate que ya este año salieron las nuevas advan v61, esas geolandar g058 son modelo viejo. Las primacy 4 son modelo viejo y te las cobran como si fuesen oro. Bridgestone y continental tambien las vi a precio de oro. Pirelli son medio pelo, no son malas pero son ruidosas, ya que estás en el baile podes ir por algo mejor, como las yokohama.”
“I'll have to remember to get some E's. That aside, the primacy 4 fitted to the mokka only have 6.5 mm, if that, from new so perhaps they were just an older name. Gaz”

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.
