Our take

The Cooper Discoverer AT3 LT is a solid choice for those who prioritize durability and off-road capability. Its 60,000-mile treadwear warranty is a standout feature, surpassing the category average, which makes it appealing for long-distance adventurers who want longevity. The 3PMSF rating also adds value for drivers needing reliable traction in light snow conditions.

In the all-terrain category, off-road traction is key, and the AT3 LT's specs suggest it's well-suited for mixed terrain use. However, its wet grip score of 4 is a weak point, underperforming the category average of 5.2, which could be problematic in wet conditions. The handling score of 6.5 matches the category average, providing predictable performance, but dry grip is slightly below average, which might not inspire confidence on dry roads.

When compared to competitors like the Toyo Open Country A/T III, which offers better wet grip, the AT3 LT might fall short for those who frequently drive in wet weather. On the other hand, its treadlife advantage makes it a compelling option for those prioritizing longevity over wet performance.

If wet grip is a critical factor for you, consider the Toyo Open Country A/T III instead. However, if you're focused on durability and off-road capability, the Discoverer AT3 LT is worth considering.

Pros

  • Off-road traction is bolstered by the 3PMSF rating, making it suitable for light snow and mixed terrain.
  • Treadlife warranty of 60,000 miles exceeds the all-terrain category average of 55,717 miles, promising longer use.
  • Handling score of 6.5 aligns with the category average, ensuring predictable performance on and off-road.

Cons

  • Wet grip performance is notably below average, which could be a concern for drivers in consistently rainy climates.
  • Wet grip score of 4 is below the category average of 5.2, which may affect performance in rainy conditions.
  • Dry grip at 6.5 slightly trails the category average of 6.6, offering less confidence on dry pavement compared to some rivals.
  • The Toyo Open Country A/T III offers a better wet grip, making it a more suitable option for those prioritizing wet performance.
