Tire A

Bridgestone Potenza RE030

We haven't collected enough community discussion about this tire yet.

Tire B

Michelin Primacy 4

Positive

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.

“I have used Michelin tires before but recently I already have used Nankang tires. I compared Michelin and Nankang tires after testing. It was quite a pleasant surprise that the Nankang AS1 was nearly on par with the Michelin Primacy 4 in braking distance. Both tires performed exceptionally well, with the Primacy 4 only stopping slightly 3 meters shorter than the AS1.”

“Rapid wear on Michelin Primacy 4, 2017 Forester 2017 Forester in Mexico City, where there are lots of potholes and speed bumps and a LOT of rain. I got a set of Michelin Primacy 4+ tires at Costco three years ago and they've got about 30,000 kms -- 16,000 miles on them. Tread is down to about 3.5/32nds (in the middle, slightly less at the sides). The original Geolandars lasted very far beyond that in the same conditions. I'm getting a bit antsy at the tread depth. Wonder if anybody else has seen such rapid wear.”

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.
