“NT555G2 are lower end performance tires. They are not even in the same class as the PSS4S you mention. If you have the money buy the Michelin PSS4s’. Also go wider in the front and rear for better traction and honestly better looks. I run Nitto NT05’s in 275/305/35R19. They are 100% stickier than the 555G2’s and on a warm day the PSS4s’ too that came with my car But that’s the point of them and the rain performance doing the actual speed limit and taking it easy in the rain fine. I have about 530 to the crank and 460 to the wheels. They will not last as long as the 555G2’s but they perform better. When it comes to pure all around best street tire though, the answer is easy the Michelin’s you mentioned are the best if you have the extra money to spend. Get a 275/295/35R19 set up since the profile of the 305 in that tire is too small at just 30 in my opinion. You’ll be very happy with those. Or get the Nitto Nt05 but expect to replace the tires every 10-15k miles depending on how rough you are on 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.
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.
