From owners
Pros, cons & observations
Themes extracted from owner reviews across retailers and review sites — not the opinion of TireWheelGuide.
The Bridgestone Dueler H/T 687 is widely regarded as a durable, long-lasting highway tire that performs reliably in dry conditions and light off-road environments. However, user consensus is polarized regarding its wet-weather capabilities, with many reporting significant traction loss and increased braking distances at higher speeds.
Pros
- Exceptional tread life and overall durability
- Reliable handling and grip in dry road conditions
- Competent performance on light tracks, dirt, and sand
- Solid value as a long-term OEM equipment choice
Cons
- Poor traction and braking performance in wet conditions at highway speeds
- Inadequate grip on snow, ice, and mud
- Increased road noise as the tire ages
- Noticeable decline in handling precision as tread depth decreases
Observations
- Suzuki owners report mixed experiences, with some finding the tire excellent for light moorland and track use, while others find it lacking in adverse weather.
- Users note that the tire's performance characteristics, particularly noise and handling, become more pronounced as the vehicle reaches higher speeds (above 60-80 mph).
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.

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.
