Dunlop Grandtrek AT20 review
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.
Two scoring systems, side by side
Owner scores come from reviews on retailer and review sites; road-test scores come from instrumented tests. Where they disagree, it is usually a discipline owners rarely push to the limit.

Pros
- Exceptional tread life and high mileage durability
- Quiet and comfortable ride on paved surfaces
- Reliable performance in dry, warm weather conditions
- Consistent availability as a factory-fitted original equipment tire
Cons
- Dangerous handling and poor traction on wet roads
- Inadequate performance in snow, ice, and mud
- Susceptibility to shoulder wear and uneven tread degradation
- Limited off-road durability and puncture resistance
Worth knowing
- Owners of heavy 4x4s like the Toyota Land Cruiser and Mitsubishi Shogun frequently report that the tire's performance does not match the vehicle's off-road capabilities.
- Some users noted that adjusting tire pressure slightly above factory recommendations can help mitigate uneven shoulder wear, though this remains a recurring complaint across various models.
