Our take

The Dunlop Grandtrek AT20 is a highway all-season truck tire that targets buyers seeking longevity and balanced on-road performance. Its 60,000-mile treadwear warranty is a strong point, offering a competitive lifespan compared to others in the segment. However, the UTQG treadwear rating of 300 is notably lower than the category average, indicating a softer compound that may wear faster than expected.

When it comes to driving dynamics, the Grandtrek AT20 holds its own with dry grip and handling scores both at 7.5, providing stable performance for everyday highway use. Comfort and noise levels are on par with the category averages, making it a reasonable choice for those who value a quiet and comfortable ride.

In comparison to competitors like the Firestone Destination LE3, which offers superior wet grip, the Grandtrek AT20 lags with a wet grip score of 5. This could be a significant drawback for drivers in wet climates. The Hankook Dynapro HT RH12 and Yokohama Geolandar H/T G056 may also be worth considering for those prioritizing wet weather performance.

Ultimately, if wet grip is a priority, consider alternatives like the Firestone Destination LE3. The Grandtrek AT20 is best for budget-conscious buyers who prioritize warranty-backed treadlife and balanced dry performance over wet traction.

Pros

  • 60,000-mile treadwear warranty is competitive, offering solid longevity for highway all-season truck tires.
  • Dry grip and handling both score 7.5, aligning closely with the category's average for stable on-road performance.
  • Comfort and noise scores of 6.5 meet category expectations, making it a balanced choice for everyday driving.

Cons

  • Wet grip performance is below average, which could be a dealbreaker for those frequently driving in rainy conditions.
  • Wet grip rating of 5 falls short of the category average of 6.1, which can be a concern in rainy conditions.
  • The Firestone Destination LE3 offers better wet grip performance, making it a stronger choice for wet climates.
  • UTQG treadwear rating of 300 is significantly lower than the category average, suggesting a less durable compound.
