What real owners are saying

From Reddit, forums and review threads. Not part of our score

Tire A

Bridgestone Turanza Serenity+

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

Tire B

Michelin Primacy 4

Positive

The Michelin Primacy 4 is generally praised for its comfortable ride, low road noise, and strong braking and safety in both dry and wet conditions. While many users report excellent tread longevity across tens of thousands of kilometers, some note faster wear on heavier electric vehicles or rough surfaces. It is viewed as a premium touring tire that is unsuitable for winter conditions, prompting some drivers to weigh its high price against newer models like the Primacy 5 or cheaper alternatives.

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.
