Our take

The Firestone Transforce AT is a practical choice for utility vehicle owners who need a tire that can handle heavy loads and mixed terrain. Its load index of 125 suggests strong off-road capabilities, while the handling and comfort scores align with all-terrain category expectations. However, the lack of a treadwear warranty and a low wet grip score of 4 are significant drawbacks, particularly for drivers in rainy climates.

In terms of positioning, the Transforce AT lacks the treadwear warranty that some competitors offer, such as the Yokohama Geolandar A/T G015, which could impact long-term cost considerations. The R speed rating also limits its suitability for high-speed highway driving, which might be a deciding factor for some buyers.

Overall, this tire is best suited for those who prioritize durability and off-road performance over wet traction and high-speed capabilities. If wet grip and a mileage warranty are important to you, consider the Yokohama Geolandar A/T G015 or the Toyo Open Country A/T III as alternatives.

Pros

  • Off-road traction is solid with a load index of 125, providing strong support for heavy-duty applications.
  • Handling score of 6.5 is right in line with the category average, making it a reliable choice for mixed terrain driving.
  • Comfort score matches the all-terrain category average of 6, offering a balanced ride on and off the road.

Cons

  • Its wet grip rating is notably low, making it less suitable for regions with frequent rain.
  • Wet grip score of 4 falls below the category average of 5.2, which could be a concern in rainy conditions.
  • No treadwear warranty is provided, unlike competitors like the Yokohama Geolandar A/T G015 which offers a mileage warranty.
  • The speed rating of R limits the tire's suitability for higher-speed highway driving compared to some rivals.
