Tire A
Positive
Michelin Pilot Sport All Season 4
Community opinion on the Michelin Pilot Sport All Season 4 is largely positive, praising its dry and wet grip, sporty handling, and ride comfort compared to stock alternatives. However, some users note trade-offs in extreme winter conditions, potential range or efficiency impacts on EVs, and faster wear on staggered setups.

“PS4S or PSAS4 tire for Alaska Summer? Went to the tire shop and all they had was one set of the A/S 4 in stock but no PS4S. I’m a bit conflicted here, because I live in Anchorage Alaska which has relatively mild summers and mostly decent roads, but we only have 50-75 degree weather. I already have blizzaks for the winter, so I want as high a performance as I can get in the summer for daily driving. Which would be better?”

“Michelin Pilot Sport All Season 4 After 21000 miles, my Pirelli P Zeros are cooked. I ended up getting Michelin Pilot Sport All Season 4. The ratings sound pretty good but wondering if any of you have them and what your experiences have been?”

Theres abaolutely no way this is just tires.”

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.
