Dunlop Grandtrek ST20 review

The Dunlop Grandtrek ST20 is generally regarded as a reliable and durable original equipment tire, particularly favored by owners of compact and mid-size SUVs. While users consistently praise its longevity and predictable handling in mixed weather conditions, some report concerns regarding sidewall cracking over time and a noticeable decline in wet-weather performance as the tread depth approaches the legal limit.

The Dunlop Grandtrek ST20 is generally regarded as a reliable and durable original equipment tire, particularly favored by owners of compact and mid-size SUVs. While users consistently praise its longevity and predictable handling in mixed weather conditions, some report concerns regarding sidewall cracking over time and a noticeable decline in wet-weather performance as the tread depth approaches the legal limit.

Pros

  • Impressive tread life and overall durability
  • Consistent and predictable handling in mixed weather conditions
  • Strong performance for light off-road and towing applications
  • Good value proposition as an original equipment replacement

Cons

  • Noticeable reduction in wet grip at lower tread depths (below 3mm)
  • Tendency for sidewalls to develop cracks or crazing over time
  • Increased road noise on rough or concrete surfaces
  • Uneven shoulder wear reported by some users

Worth knowing

  • Owners of shorter-wheelbase vehicles like the Daihatsu Terios noted potential bounciness, though it was unclear if this was tire-specific or vehicle-geometry related.
  • The tire is frequently cited as a preferred original equipment choice for Nissan SUVs, with users often opting to repurchase the same model after the initial set wears out.
