Our take

The Cooper Discoverer S/T Maxx is a solid choice for off-road enthusiasts who value durability and handling. Its treadlife score of 8.3 is significantly higher than the all-terrain category average, indicating a long-lasting tire that can handle rough terrains without frequent replacements. However, the absence of a treadwear mileage warranty is a notable downside, especially when competitors like the Yokohama Geolandar A/T G015 offer a 50,000-mile warranty.

In terms of on-road performance, the Discoverer S/T Maxx holds its own with a handling score of 6.5, matching the category average. Its dry grip is also competitive, making it a reliable option for dry conditions. However, its wet grip score of 4 falls short of the category average, which could be a concern during rainy weather. Additionally, the lack of a 3PMSF rating limits its effectiveness in severe winter conditions, making it less versatile than some competitors.

For buyers who frequently encounter wet roads or require winter performance, the Discoverer S/T Maxx may not be the best fit. Instead, consider alternatives like the Toyo Open Country A/T III or the Pirelli Scorpion Zero All Season, which may offer better wet traction and seasonal versatility.

Pros

  • Treadlife score of 8.3 is well above the all-terrain category average, suggesting longer intervals between replacements.
  • Handling score of 6.5 matches the category average, providing predictable on-road performance.
  • Dry grip rating of 6.5 is nearly on par with the category average, making it reliable for dry conditions.

Cons

  • Wet grip performance is below average, which could be a safety concern in rainy conditions.
  • Wet grip score of 4 is below the category average of 5.2, which could be a concern in rainy conditions.
  • No treadwear mileage warranty, unlike competitors like the Yokohama Geolandar A/T G015, which offers a 50,000-mile warranty.
  • The Discoverer S/T Maxx lacks the 3PMSF rating, limiting its capability in severe winter conditions compared to some rivals.
