Pros, cons & observations

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

Tire A 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

Tire B R1R

Pros

  • Exceptional dry grip and cornering stability
  • Predictable handling and communicative steering feedback
  • Strong wet-weather performance for a performance-oriented tire

Cons

  • Rapid tread wear due to soft compound
  • Prone to overheating and 'greasy' performance during prolonged track use
  • Increased road noise compared to standard street tires

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.
