From owners
Pros, cons & observations
Themes extracted from owner reviews across retailers and review sites — not the opinion of TireWheelGuide.
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
Observations
- 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.
The Toyo Open Country H/T is generally regarded as a durable, long-lasting highway tire that excels in dry conditions and offers a quiet, comfortable ride for daily commuting and light towing. However, user consensus is polarized regarding its wet-weather performance, with a significant number of drivers reporting poor traction, hydroplaning, and a lack of confidence in rain or snow as the tread wears down.
Pros
- Excellent tread life and durability
- Quiet and smooth ride quality on highways
- Strong performance on dry pavement
- Good value for the price point
Cons
- Significant loss of wet-weather traction as tread wears
- Vague steering feel and sidewall flex during cornering
- Inconsistent performance in heavy snow or icy conditions
- Reported hydroplaning at highway speeds
Observations
- Drivers of heavier vehicles like motorhomes and full-size trucks appreciate the durability but occasionally note a 'wallowy' or vague handling feel.
- Users of smaller SUVs (e.g., Forester, CR-V) frequently reported understeer and poor wet-road grip, suggesting the tire may be better suited for heavier truck applications than lighter crossovers.
- Owners of high-torque diesel trucks report positive experiences with tread longevity, though some note the tire is not ideal for heavy-duty towing compared to specialized alternatives.

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.
