Pros, cons & observations

Themes extracted from owner reviews found online — not the opinion of TireWheelGuide.

Tire A Azenis RT-615K

Not enough owner reviews yet to extract themes.

Tire B NT555 G2

Pros

  • Aggressive, visually appealing tread pattern and sidewall design
  • Exceptional value and lower price point compared to premium brands like Michelin or Pirelli
  • Long-lasting tread life and slow wear rates for a summer performance tire

Cons

  • Poor wet-weather traction, with multiple users reporting hydroplaning and a slippery feel in the rain
  • Lack of straight-line traction and wheel spin under heavy acceleration, especially on high-horsepower RWD vehicles
  • Subpar performance in cooler temperatures or cold conditions, requiring heat to grip properly

We haven't collected enough community discussion about this tire yet.

Tire B

Nitto NT555 G2

Mixed

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.

“I have the nittos NT555 G2s on my mustang and they have lasted about 30k miles. But I wouldn't call them ultra high performance by any stretch of the word. I put firestone firehawk indy 500s, 305s on all 4 corners of my widebody scatpack and think it's a far superior tire in terms of grip, style and rain grooves for wet traction.”

“Staggered tire recommendations? Title. I have 17x9 rims up front and 17x10.5 rims in the rear. Currently running 245/45R17 on the front and 275/40R17 in the rear. Ideally I’d like to keep these tire sizes. Tires all around are Nitto NT555 G2 tires, and I’m just not happy at all with the grip. They’re fine around corners, but if I even breathe on the throttle at all in 1st gear, I’m instantly spinning. It’s sketchy as fuck in the rain, too. I wanted Continental DWS06 tires, but they don’t make those in a 275/40R17 for my rear tires. I’d only be able to get the fronts. Thinking about Michelin Pilot Sport A/S 4s, but not sure. I want to be able to handle well enough around corners, handle Ohio weather no matter what it’s doing, and I wanna be able to floor it in 1st gear and get very little wheel spin. Obviously not trying to drive the car in snow, it’s still mostly gonna see nice weather and occasional rain, I usually like to store the car over the winter and drive something else. But still, Ohio is Ohio, and our weather can absolutely never make up its damn mind. So, I come asking for tire recommendations. Don’t really mind price all too much, but my car is completely stock engine wise minus the exhaust, so it’s not like I’m pushing crazy power. I “daily” this car whenever the weather is nice, so I just need a streetable all season tire that won’t lose grip instantly whenever I try having a little fun. Thanks!”

“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”

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.
