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.

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.

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.
