Tire B Dunlop Grandtrek ST30

The Dunlop Grandtrek ST30 receives highly polarized feedback, often serving as polarizing original equipment on popular SUVs like the Honda CR-V and Toyota RAV4. While some users praise its dry-road stability, longevity, and value, a significant portion of owners report dissatisfaction regarding wet-weather confidence, excessive road noise, and inconsistent tread wear.

Pros

  • Strong dry-pavement grip and straight-line stability
  • Competitive price point and value for money
  • High mileage potential for some drivers
  • Capable performance on light unpaved or rural roads

Cons

  • Poor wet-weather performance and susceptibility to aquaplaning
  • High levels of road noise on various surfaces
  • Inconsistent tread life, with reports of rapid wear
  • Lack of confidence in winter conditions, including snow and ice

Observations

  • Users of AWD vehicles like the Honda CR-V and Toyota RAV4 report highly variable experiences, ranging from excellent longevity to premature wear and poor wet-traction handling.
  • The tire is frequently criticized for its lack of winter capability, with many owners noting it is unsuitable for anything beyond light, dry conditions.

How do we compare tires?

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.
