Best test result: #1 of 9 in 2021 EVO Summer Tyre Test (wet handling)
“Pirelli P Zero Tyres But if a rant. Brought my i4 edrive 40 about 14 months ago from a main dealer here in the UK. The front tyres (Hankook) had decent tread, obviously the rears did not, so the dealer swapped them for brand new Pirelli PZero (PZ4) tyres at the rear. Honest to god I have never driven tyres so dam trash in my life. Anything other than a perfect warm dry day, there is little to no grip and car struggles to put its power down. I assume the Zero in P Zero refers to the grip levels. Just wondered if anyone else had any experience with Pirelli’s? Read more”

Negative
Pirelli P Zero (PZ4)
Community sentiment regarding the Pirelli P Zero (PZ4) is largely critical, with users reporting extremely rapid tread wear and severe grip issues outside of warm, dry conditions.

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.
Community buzz from Reddit and forums is shown for context only — it never changes the score.
