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 Yokohama Geolandar G900 is widely regarded as a highly capable, versatile all-rounder specifically engineered for Subaru Forester and Outback platforms. While users consistently praise its predictable handling, off-road traction, and comfort, the consensus is sharply divided regarding its tread longevity and value proposition compared to modern alternatives.
Pros
- Excellent all-terrain versatility including snow, gravel, and mud
- Predictable and secure handling characteristics
- High level of ride comfort compared to stiffer premium alternatives
- Strong initial grip and traction performance
Cons
- Inconsistent tread life with many reports of premature wear
- High road noise levels, particularly on motorways
- High price point relative to current market competitors
- Occasional reports of poor wet-weather performance and aquaplaning
Observations
- The tire is specifically optimized for the Subaru Forester and Outback chassis, with many users noting it complements the vehicle's suspension better than stiffer premium tires.
- Performance is highly dependent on alignment; several users noted that uneven wear patterns were mitigated by professional tracking checks.

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.
