Our take

The Rocky Mountain All Terrain tire is a solid choice for drivers who frequently venture off the beaten path. Its off-road traction is a key strength, making it suitable for varied terrains. The tire's 50,000-mile treadwear warranty and a treadlife score of 7.5 suggest a reasonable lifespan, although not the longest in the category.

In terms of wet grip, the tire performs above the category average with a score of 6, providing better-than-average performance in wet conditions. However, its dry grip score of 6.5 is slightly below the category average, which might be a concern for those who prioritize on-road performance. Noise levels are average, so while not a standout, they won't be a dealbreaker for most.

Compared to competitors like the Toyo Open Country A/T III, which offers a higher treadwear warranty, the Rocky Mountain All Terrain may not be the most cost-efficient choice for high-mileage drivers. However, it holds its own against the Pirelli Scorpion Zero All Season and Yokohama Geolandar A/T G015 in terms of off-road capability.

If you prioritize on-road performance and long-term cost efficiency, consider alternatives like the Toyo Open Country A/T III. But if off-road traction is your main concern, the Rocky Mountain All Terrain is worth considering.

Pros

  • Off-road traction benefits from a balanced tread design, making it suitable for varied terrains.
  • Treadlife score of 7.5 and a 50,000-mile warranty offer decent longevity compared to some all-terrain rivals.
  • Wet grip score of 6 is above the category average of 5.2, providing better-than-average performance in wet conditions.

Cons

  • Dry grip is slightly below average, which may not be ideal for those who prioritize on-road performance.
  • Dry grip score of 6.5 is slightly below the category average of 6.6, which may affect performance on paved roads.
  • Noise level is average for the category, but still a concern for those sensitive to cabin noise.
  • The Toyo Open Country A/T III offers a higher treadwear warranty, which could be more appealing for long-term cost efficiency.
