Themes extracted from owner reviews across retailers and review sites — not the opinion of TireWheelGuide.
The Dunlop Grandtrek A/T20 is a polarizing tire that is frequently criticized for its poor wet-weather performance and limited off-road capability, despite being a common original equipment choice for various 4x4s. While a significant portion of users report exceptional tread longevity and acceptable dry-road comfort, many owners find the lack of confidence in rain and snow to be a safety concern that outweighs the tire's durability.
The Dunlop Grandtrek SJ6 receives a highly critical assessment from the user, who reports significant performance deficiencies in both wet and dry conditions. The reviewer expresses extreme dissatisfaction, citing poor handling and braking capabilities.

Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements) normalized against the best tire in each test and weighted toward recent tests. 40% comes from thousands of owner reviews collected from retailers and review sites. When a tire has only one of the two, we use what exists and say so.
Community buzz from Reddit and forums is shown for context only — it never changes the score.
