Our take

The Nitto NT555RII is aimed at drivers who want a tire that can handle the demands of track days or spirited driving sessions. Its dry grip and handling scores of 8 make it a solid performer in dry conditions, although it doesn't quite match the top performers in its category like the Michelin Pilot Sport 4S.

In terms of comfort, the NT555RII holds its own with a score of 6, which is on par with the category average. However, its wet grip score of 7 is below the average, suggesting that it may not inspire confidence in wet conditions. The tire's UTQG treadwear rating of 100 is a clear indicator of its short lifespan, especially when compared to the category average of 935. This makes it less suitable for those who rack up high mileage.

When compared to competitors like the Michelin Pilot Sport 4S and Pirelli P Zero (PZ4), the NT555RII sacrifices longevity and wet performance for dry grip and handling. This tire is best for those who prioritize performance over practicality. If you need a tire with a longer tread life and better wet performance, consider the Michelin Pilot Sport 4S instead.

Pros

  • Dry grip rating of 8, while below the category average of 8.7, still offers solid performance for spirited driving.
  • Handling score of 8 matches the dry grip, providing a responsive driving experience.
  • Comfort score of 6 aligns with the category average, making it reasonable for a performance-focused tire.

Cons

  • The extremely low treadwear rating of 100 suggests a very short lifespan, which could be costly for frequent drivers.
  • Treadwear rating of 100 is significantly below the category average of 935, indicating a much shorter lifespan.
  • Wet grip score of 7 falls short of the category average of 7.6, which could be a concern in rainy conditions.
  • The Michelin Pilot Sport 4S offers better wet grip and a longer tread life, making it a more balanced choice for those who drive in varied conditions.
