Our take

The Cooper Discoverer ATP II is a solid choice for those who need a durable all-terrain tire with a focus on longevity. Its 60,000-mile treadwear warranty surpasses the category average, making it a reliable option for drivers who spend a lot of time off-road. However, its wet grip score of 4 is a significant drawback, especially for those who frequently encounter wet conditions.

In the all-terrain category, off-road traction and treadlife are key priorities, and the Discoverer ATP II's 600 UTQG treadwear rating and matching comfort score make it a balanced choice for mixed-use driving. However, its dry grip is slightly below the category average, which might affect its on-road handling performance.

When compared to competitors like the Toyo Open Country A/T III, which offers better wet grip, the Discoverer ATP II may not be the best choice for wetter climates. The Pirelli Scorpion Zero All Season and Yokohama Geolandar A/T G015 also offer competitive options with varying strengths in handling and grip.

Drivers who frequently encounter wet roads should consider alternatives like the Toyo Open Country A/T III for better wet performance. However, if off-road durability and a strong warranty are your main concerns, the Discoverer ATP II remains a viable option in its segment.

Pros

  • Off-road traction benefits from a 600 UTQG treadwear rating, supporting long-lasting performance on varied terrains.
  • 60,000-mile treadwear warranty exceeds the all-terrain category average of 55,717 miles, promising extended durability.
  • Comfort score of 6 matches the category average, making it a reasonable choice for mixed on-road and off-road use.

Cons

  • Wet grip performance is notably below average, making it less suitable for drivers in consistently rainy regions.
  • Wet grip score of 4 falls below the category average of 5.2, which could be a concern in rainy conditions.
  • Dry grip is slightly under the category average of 6.6, which might affect handling on paved surfaces.
  • The Toyo Open Country A/T III offers better wet grip, making it a more reliable option for drivers in wetter climates.
