“The Pilot Sport 4's are great tires for dual duty use. You'll want to keep hot pressures below 37-38 PSI. Anything above that they get very greasy, very fast. In the cars I've driven with them (a few BMW M cars, a 911 I think if I remember), you'll usually set your best laps in the first 4-5 laps of a session depending on temps. Once they over heat heat, as with any street tire, you have to park them for an hour to get the temps down again (downside to steel radials). I'd also recommend Hankook RS4s if you want a more durable track tire. That's what I run. Very long lasting, but not as great in the wet as the PS4s would be. Road noise would also be an issue for street use.”

“Much deserved extra care and new PS4 tires today! Switched over to Michelin PS4 High Performance summer tires from Continental run flats on my C43, and it’s a world of difference in terms of ride quality and noise. She also got the much needed love and care with a nice hand car wash! Jealous GL63 peeking from behind, next post will be a side-by-side photo!”

“I basically always ran Michelins on the BMWs I had. Pilot Super Sport on the E91 335d (which unexpectedly did really well wrt longevity with 600nm+ and a heavy foot) and now PS4 ZP (so the runflat type) on my 320hp F31 330d. They are just really really good. Pretty pricey though.”

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.
