Our take

The Bridgestone Turanza ER300 is best suited for drivers who prioritize dry grip and handling over other attributes. With scores of 9.5 in both dry grip and handling, it surpasses the category average, making it a compelling choice for those who enjoy spirited driving. However, its wet grip score of 5.5 falls short of the category benchmark, which could be a concern for those frequently driving in wet conditions.

In the grand touring all-season category, comfort and noise are also important, and the Turanza ER300 meets the category averages in these areas with scores of 8. This ensures a comfortable and quiet ride, which is expected in this segment. The Y speed rating further supports its performance credentials, allowing for high-speed stability.

When compared to its competitors, such as the General AltiMAX RT45 and BFGoodrich Advantage Control, the Turanza ER300 lacks a treadwear warranty, which could affect its long-term cost-effectiveness. The General AltiMAX RT45, for instance, offers a mileage warranty that the Turanza ER300 does not, making it a better option for those concerned with longevity.

Overall, if wet performance and treadwear warranty are priorities, consider alternatives like the General AltiMAX RT45. However, if dry performance is your main focus, the Turanza ER300 is worth considering.

Pros

  • Exceptional dry grip and handling scores of 9.5, well above the category average of 7.6, making it a strong choice for spirited driving.
  • Comfort and noise scores both at 8, matching the category benchmarks, ensuring a smooth and quiet ride.
  • Y speed rating supports high-speed stability, suitable for performance-oriented drivers.

Cons

  • Wet grip performance is notably below average, which could be a dealbreaker for drivers in rainy climates.
  • Wet grip score of 5.5 is significantly below the category average of 7.4, which could be a concern in rainy conditions.
  • No treadwear warranty provided, unlike competitors like the General AltiMAX RT45, which offers a mileage guarantee.
  • Limited treadlife score of 6 compared to the category average, suggesting more frequent replacements may be needed.
