From owners

Pros, cons & observations

Themes extracted from owner reviews across retailers and review sites — not the opinion of TireWheelGuide.

Tire A Bridgestone Dueler H/T 687

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).

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.
