“Wow! You burn rubber. I totally appreciate what you’ve said and on my old e60 I ran both contis D06 and Michelins ps4 for 3 sets each. Both different feel and wear. Contis lasted longer but didn’t feel as nice as PS4. Now I’m in another BMW and cannot rotate the same way with a staggered wheel size. I’m in NC, when I drove PS4, in cold weather, they wore out quickly. They are a summer tire for sure, but I will use a slightly higher pressure to lengthen service life. That camber is rough on the inner tire shoulder / tread and the all season contains held up better there.”

Tire A

Michelin Pilot Sport 4

Positive

Community opinion on the Michelin Pilot Sport 4 (and PS4S) is overwhelmingly positive, with users frequently praising the massive grip, excellent steering feel, and dramatic improvements in ride quality compared to OEM run-flats. While some note that they wear out relatively quickly and can be noisy on highways or sensitive to cold temperatures (below 40°F), they are widely considered a top-tier performance tire for both daily driving and spirited use.

“I switched to ps4s. Sidewall is a little softer so they have a more comfortable ride at the expense of a little numbness during normal driving. Grip limits seem pretty similar. Ps4s should last longer. We'll see. Would buy again over stock dunlops.”

“PS4 tires for sale (OEM 18” takeoffs) I’ve got some PS4 take offs for sale. Only 2000 miles on them. Asking $400. Located in Boulder Colorado area. Willing to meet up within a few hundred miles. No tears, plugs or curbing. Read more”

“Reminder: Tires are the key to this car Just replaced my Michelin Pilot Sport 4 AS tires with a new set ahead of the rainy season. Lasted 36K miles. It was the best mod to the car and a fresh set reminded just how good a brand new set is. The car is glued to the road, riding wonderfully smooth and quiet. Spend the money, get the best tires for you. The tune can wait. And it will need it.”

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.
