    No owner ratings of noise for Pilot Sport 5. The owner half is the owners’ average (67): owners’ noise ratings barely follow the road tests, so the tests say nothing about how owners would rate it.

What real owners are saying

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

Tire A

Kumho Solus HS51 Harmony Sports

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

Tire B

Michelin Pilot Sport 5

Positive

Community opinion on the Michelin Pilot Sport 5 is overwhelmingly positive for daily street driving, praising its exceptional wet grip, tread longevity, and quiet comfort compared to run-flats and older performance tires. However, several enthusiasts note downsides for aggressive or track use, specifically citing softer sidewalls, muted steering feedback, and poor heat resistance leading to delamination under track conditions. Most drivers consider it an outstanding premium all-rounder for sporty street cars rather than a dedicated track or extreme-performance tire.

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.
