“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”

Themes extracted from owner reviews found online — not the opinion of TireWheelGuide.
From Reddit, forums and review threads. Not part of our score
The community sees the FK510 as a good-value ultra-high-performance summer tire, with strong wet grip, decent dry grip, and comfort that is often described as good. It is usually pitched as a cheaper alternative to the Michelin PS4S, Continental ExtremeContact Sport and similar tires. Common complaints are fast tread wear (often 10–15k miles, and less on heavy or powerful cars or when tracked), road noise for some owners, and weaker braking and handling balance in some tests.
“2022 MS Plaid on 21" archnids. Factory Michelins replaced at 7,500 miles (at wear markers). FK510's after 9,000 miles on the rubber are at 7/32. Expecting another 5,000 miles or so. They're comparable treadwear rating but last longer. Heavy car with lots of torque will inevitably go through tires sooner than the rated mileage. I'm fortunate to have decent alignment from the factory as the wear was even. Good luck on the next set of tires.”
“Accidentally bought a Falken FK510 at discount tire when my other rear tire is a FK460A/S I have a brand new 460A/S on my driver rear a week ago and I went to discount yesterday and accidentally bought the 510 for my passenger rear. My biggest concerns is the difference in grip and wear and for the torsen limited slip on my GT PP1. I just daily my car to work and floor it at lights and don’t do canyon or track runs. I saw discount tire has a return / exchange policy, has anyone gone this route?”
“I purchased a full set of Falken Azenis FK510 tires in January of last year. Ride, quietness, and wet/dry handling were all right on the money with the Tire Rack and other reviews that I looked over when deciding which tires to buy. Now I'm wishing I'd gone ahead and spent the extra money to get another set of Michelins. The rear tires are completely worn down now after only daily driving the car and putting maybe 15k miles on the tires. The same driving conditions with the previous Michelin PSIII tires resulted in the tires lasting for 5 years and 50k miles. Tread wear is the only complaint I have with these tires, but it is one massive issue with tires only lasting 15k miles with tame daily driving. My advice is to spend the extra money and get the Michelin tires. That's what I'll be doing this weekend.”

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. While some drivers consider them for OEM run-flat availability, multiple posts highlight concerns over poor longevity and lackluster wet and cold weather performance compared to competitors like Michelin.

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.
