“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.”

What real owners are saying

Tire A

Bridgestone Turanza GR90

We haven't collected enough community discussion about this tire yet.

Tire B

Michelin Pilot Sport 4

Positive

The community widely regards the Michelin Pilot Sport 4 line as a premium upgrade offering exceptional dry and wet grip, precise handling, and superior ride comfort compared to OEM or run-flat tires. While celebrated for performance, users frequently discuss its high price tag, faster treadwear, and noticeable drop in EV efficiency. Some drivers also note increased road noise and reduced traction when temperatures drop near freezing.

“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.”

Since I put the pressure to the mid point between the low and high load plated pressures I have yet to have any of the heartstopping thumps come through the suspension that the Bridgestone seemed prone to.”

“I was running pilot sport 4s on my MS. (19” wheels) I was lucky to get 13,000-14,000. I just switched to Kumho Majesty 9’s for about 1/3 the price. Currently have 4,000 miles on them and just to rotated. Fingers crossed I can get 13,000 miles out of them.”

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.
