“If you drive the car as a weekend driver, as I do, then I think the Firestone summer tires are the best bet. Maximum performance, best feel, etc. I will put only 1000 to 2000 miles a year on my car. However, if I were to use the car more, I would choose a Michelin max performance all season tire. These are nearly as good as the Firestones will be, in the dry, but will be quieter, smoother riding, and last twice as many miles. Michelin makes the world's best tires and no other company even comes close. I would have bought Michelin but they don't make a summer tire in our size. But they do make this and it would be my choice if I drove the car more. They're only a bit more money than the Firestones: MICHELIN PILOT SPORT ALL SEASON 4 Ultra High Performance All-Season Size: 205/45ZR17 88Y XL”

“I got 30k miles out of the pilot sport 4s and pilot sport all season 4. The cost difference was not too bad and the all season 4 grip almost as well and are rated to 11f vs 40f for the pilot sport 4s. And they all wore evenly. Upsizing definitely made it feel more planted 245 275.”

“Im running pilot sport a/s4 in 265/35 r18 on 18x9.5 konig ampliform. I have been driving them about 5 months, i cant complain. They are good for where im at (only 93 octane stage 1 tune, no major mods). Side note, i feel the road imperfections alot more with such a small sidewall.”

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.
