“Nitto NT555 G2 is good for the price. It's decent all around. Great treadwear rating, looks good but does NOT want to perform at all if a little bit cold. MP4S if you don't mind spending extra. A bit more grippy and better in the rain for sure.”

Community opinions on the Nitto NT555 G2 are mixed, often positioning it as an affordable, good-looking tire with decent tread life that performs adequately in warm weather. However, many enthusiast drivers note that it struggles significantly with straight-line traction, wet weather grip, and cold temperatures compared to higher-end alternatives like the Michelin Pilot Sport 4S.
“Try the NT555G2 up front and the NT555RII in the rear. I hook all the time after the tires warm up.”
“Update! I ended up going with the Nitto NT555 G2’s, thanks for all the suggestions. They are amazing tires! They ride smooth for an ultra performance, the price was friendly, and they grip extremely well!”
“How to make the most of my nt555 g2s? Hey, I have 285 front 305 rear 20" 555 g2s on my Camaro 1LE and I'm really struggling at autocross. I find that my braking ability and front grip mid corner are aweful. I drove a friend's car on Better 200tw tire and loved out. How can I make the most of my G2? I ran 28psi last event. I'm not trying to win a class, just learning what I can. I plan on upgrading tires after I burn these but I don't want to drop 1400 on good tires until I need to since my car is not only used at Autocross. It's drag raced, autoXd, going to go to a road course, and I want to go to Canada and the tail of the Dragon lol. Yes, I know wheels/tires for the street and track Seperate would be the best idea Read more”

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.
