Best test result: #2 of 14 in 2018 New and Worn Summer Tyre Test (noise)
“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.”

Tire A
Michelin Primacy 4
Positive
Community feedback for the Michelin Primacy 4 is largely positive, highlighting its excellent balance of low road noise, high comfort, dependable wet and dry grip, and strong longevity for daily driving. While some users note concerns over rapid wear on specific heavy or EV applications, and poor snow performance due to its summer tire nature, most drivers find it a superior touring tire compared to factory options.
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.
