NT555 G2
Pros, cons & observations
Themes extracted from owner reviews found online — not the opinion of TireWheelGuide.
Tire A NT01
Pros
- Exceptional dry grip and traction once warmed up
- Outstanding tread life and durability for a track tire (wears like iron)
- Consistent performance across multiple heat cycles with minimal degradation
Cons
- High risk of hydroplaning and poor performance in heavy rain or standing water
- Loud road noise and harsh ride quality when used for street driving
- Slow to warm up properly on the street, leading to faster wear off-track
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

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.
