Our take

The Dunlop Grandtrek ST30 is a budget-friendly option for highway all-season truck tires, with its standout feature being the wet grip score of 7, which surpasses the category average. This makes it a solid choice for drivers who frequently encounter wet conditions. However, the absence of a treadwear warranty can be a significant downside, especially when competitors like the Firestone Destination LE3 offer a 70,000-mile warranty, potentially reducing the long-term cost of ownership.

In terms of performance, the Grandtrek ST30 delivers average handling with a score of 7.5, aligning with the category benchmark. Its dry grip score is slightly below average, which might impact performance in dry conditions. Additionally, the R speed rating may not be ideal for those who require higher-speed capability on highways.

When compared to its competitors, the Grandtrek ST30 offers better wet grip than the Hankook Dynapro HT RH12 and the Yokohama Geolandar H/T G056, but it falls short in warranty and speed rating. For drivers who prioritize wet traction and are on a budget, this tire could be a reasonable choice. However, those who drive high annual mileage or require a higher speed rating might want to consider alternatives like the Firestone Destination LE3.

Drivers seeking a tire with a solid warranty and better dry grip should look elsewhere, as the lack of a treadwear warranty and lower dry grip performance are notable drawbacks of the Grandtrek ST30.

Pros

  • Treadlife rating of 6.3 is competitive, though no mileage warranty is provided — typical for budget options.
  • Wet grip score of 7 is above the category average of 6.1, offering better traction on rainy days.
  • Handling score of 7.5 matches the category average, providing reliable on-road performance.

Cons

  • Lack of a treadwear warranty means potential higher long-term costs compared to competitors like the Firestone Destination LE3.
  • No treadwear warranty, unlike the Firestone Destination LE3 which offers a 70,000-mile warranty.
  • Dry grip rating of 7.5 falls slightly short of the category average of 7.7, which could affect performance in dry conditions.
  • The speed rating of R is lower than some competitors, limiting its suitability for higher-speed highway travel.
