Best test result: #1 of 9 in 2024 Tire Rack UHP All Season Tyre Test (snow braking)
“I just switched from the Pilot Sport All Season 4 to the Continental DWS 06 Plus, and the contis are WAY quieter and ride so much smoother than the Michelins. Hopefully they'll last longer too, the Michelins only lasted me about 28k~ miles despite regularly rotating them.”

Tire B
Positive
Michelin Pilot Sport All Season 4
Community sentiment for the Michelin Pilot Sport All Season 4 is predominantly positive, with drivers praising its dry and wet grip, responsive handling, and substantial upgrade over stock tires. However, several users report drawbacks including mediocre deep snow performance, noticeable road noise or ride stiffness compared to competitors like the Continental DWS 06 Plus, and an efficiency or range penalty on electric vehicles.

“I use these on my F80 M3 competition with the 666M wheels for the winter. I had Continental DWS 06 Plus on my E90 M3. The PSAS4 have stiffer side wall than the DWS06 Plus, so the ride will feel more sporty if that's what you're after. PSAS4 also have slightly more dry pavement grip and tad more steering feel than the DWS. The DWS is a tad bit quieter and softer sidewall. Superior to the PSAS4 in light snow. Dry pavement grip is still amazing. I have 2 sets of 666m wheels for my F80 comp. One set outfitted with Pilot sport all season 4 and the other set outfitted with Pilot sport 4s.”

“New Tires (Michelin Pilot Sport All-Season 4) I know this has been discussed a lot here so I won't go into a ton of detail, but I recently got a '23 GT (DCT, around 30k miles) and the stock tires were so ASS. Decided to grab the ones in the title and it's literally night and day difference. I was getting terrible traction when just barely accelerating w/ stock tires. Now I can basically floor it. Same with braking; felt pretty damn bad before, and so much better now. The ride, in general, also just feels more comfortable (smoother, though I didn't notice a huge sound difference, but I usually have music on anyway). Haven't gotten to really push it on turns or anything yet, but it's definitely a big difference already with the small bit of driving I did after getting them installed. I did also go with 235 over the stock 225.”

“Michelin Pilot Sport All Season 4 efficiency FOLLOWUP: On a recent drive, similar speed (70-80) and same route, I managed to get 290Wh/mi. Only notable difference was that the outside temperature was now 25-30C (instead of <10C) In trying to debug WTF tesla is doing, I started looking at the CAN bus. It appears that the car tries to keep the battery in the 30-35C range, so pretty much all that extra power usage was the car trying to maintain battery temperature in cold weather rather than the tires. Original post--------------------------------------------: just FYI about Michelin Pilot Sport All Season 4 235/45zr18 98Y I knew to expect a small efficiency hit, but this is almost as bad as when I towed a 2000lb boxy trailer. M3LR, stock 18" wheels and aero covers, no roof rack, no bike rack, driving in ~10-15C ~70-80mph funny part is that with the $0.46/kWh supercharging for the California portion of the road trip, driving a Tesla comes out more expensive than a 22mpg gas car @$4/gal :rofl: Read more”

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.
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.
