Our take

The Cooper Discoverer Road+Trail AT is a solid choice for drivers who need a durable all-terrain tire with a long lifespan. Its 65,000-mile treadwear warranty and a treadlife score of 8.5 set it apart from many competitors in the segment, where the average warranty is just over 55,000 miles. This makes it particularly appealing for those who rack up high mileage on varied surfaces.

In terms of performance, the Road+Trail AT offers a wet grip score of 6, which is above the category average, indicating it handles rainy conditions better than many all-terrain options. However, its dry grip is slightly below the average, which could be a concern for drivers who spend a lot of time on dry pavement. The tire's 3PMSF rating suggests it can manage light snow, adding to its versatility.

When compared to competitors like the Toyo Open Country A/T III and Yokohama Geolandar A/T G015, the Discoverer Road+Trail AT stands out for its treadlife but falls behind in dry grip and noise levels. The Pirelli Scorpion Zero All Season might be a better fit for those who prioritize on-road handling.

Drivers who prioritize a quiet ride or enhanced dry grip might want to explore other options, such as the Yokohama Geolandar A/T G015, which may offer a quieter and more refined driving experience on highways.

Pros

  • Treadlife rating of 8.5 and a 65,000-mile warranty exceed the all-terrain category average of 55,717 miles, promising longer service life.
  • Wet grip score of 6 is above the category average of 5.2, which helps with traction during rainy conditions.
  • The 3PMSF rating indicates it can handle light snow, adding versatility for mixed-weather use.

Cons

  • If you prioritize dry grip or a quieter ride, consider other options like the Yokohama Geolandar A/T G015.
  • Dry grip score of 6.5 is slightly below the category average of 6.6, which might be noticeable on dry pavement.
  • Noise level is average for the category, but competitors like the Yokohama Geolandar A/T G015 might offer a quieter ride.
  • The Pirelli Scorpion Zero All Season offers better on-road handling, which could be a consideration for drivers who prioritize highway performance.
