“Surprised by Michelin Pilot Sport 4 tires - 2024 M440i Hey, BMW community. A year ago, I was lucky enough to order a 2024 M440i GC Xdrive. Spent hours driving different BMW's, tweaking my order sheet before my allocation was filled. Got the adaptive suspension, with 19's on Pirelli run-flats. After a few months, my San Remo GC was delivered. GREAT car. Now with ~17k miles, it was time for a routine service. And, apparently, new rear tires. Decided to just replace them all at the dealer. Went with what they recommended; Michelin Pilot Sport 4 (Star marked). What an upgrade! Steering feel, precision, comfort AND quiet. Anyone on the fence about the Pilot Sport 4 - highly recommended.

What real owners are saying

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

Tire A

Michelin Pilot Sport 4

Positive

The Michelin Pilot Sport 4 (and its variants) is widely praised by the community as a massive upgrade over stock run-flats and budget tires, offering exceptional dry and wet grip, precise steering feel, and improved ride comfort. While users frequently note trade-offs in tread life due to the softer rubber compound, and higher pricing, it remains a top-tier recommendation for spirited street driving and performance cars.

“Michelin Pilot Sport 4 tires are noisy (a followup) I have been asked on this sub if the PS4 tires on my wife’s Bolt are noisy, and I wasn’t sure how to answer. Well, we made two 60-mile round trips this past weekend, mostly on highways with 55 and 70 mph speed limits, and I have to say that the tires are kind of noisy. Certainly not as quiet as EV-oriented tires are. The grip is fantastic, so we really like them. If you are sensitive to noise, though, these Max Performance class tires are probably not for you.”

“I just installed A/S PS4 from Michelin on my BRZ recently & man they are so nice. How quiet it is, is wow, night and day. They handle quite nice except when it's still cold (sub 40F) on highway, traction control triggers but it may bc I'm lowered and yet to do my alignment. I don't know compared to stock, I was on Falken prior. I am using different tire set-up then stock however. I have 245/35 at the front and 265/35 in rear. My only regret is not going up to 40 on the sidewall for more meat. This is on 18" wheels.”

“Those are Pilot sport 4 (all season). If it had s after the 4 it would be the summer high performance version. I put the pilot sport 4 on wife's GTI autobahn 2016. Great handling tire, stiff side walls, not the smoothest ride but best overall.”

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.
