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 840 is generally regarded as a competent, comfort-oriented highway tire that excels in fuel efficiency and on-road manners. While it may not offer the extreme longevity of rugged all-terrain alternatives, users appreciate its balanced performance, particularly regarding wet-weather grip and ride quality.
Pros
- Improved fuel economy compared to aggressive all-terrain tires
- Superior wet surface traction and grip
- High level of on-road ride comfort
- Reliable tread life for standard highway usage
Cons
- Lower tread longevity compared to heavy-duty off-road tires
- Less aggressive aesthetic and capability than dedicated all-terrain options
Observations
- Users transitioning from heavy-duty all-terrain tires (such as the BF Goodrich KO2) to this model report significant gains in fuel efficiency and daily driving comfort on pickup trucks.
The Dunlop Grandtrek A/T20 is a polarizing tire that is frequently criticized for its poor wet-weather performance and limited off-road capability, despite being a common original equipment choice for various 4x4s. While a significant portion of users report exceptional tread longevity and acceptable dry-road comfort, many owners find the lack of confidence in rain and snow to be a safety concern that outweighs the tire's durability.
Pros
- Exceptional tread life and high mileage durability
- Quiet and comfortable ride on paved surfaces
- Reliable performance in dry, warm weather conditions
- Consistent availability as a factory-fitted original equipment tire
Cons
- Dangerous handling and poor traction on wet roads
- Inadequate performance in snow, ice, and mud
- Susceptibility to shoulder wear and uneven tread degradation
- Limited off-road durability and puncture resistance
Observations
- Owners of heavy 4x4s like the Toyota Land Cruiser and Mitsubishi Shogun frequently report that the tire's performance does not match the vehicle's off-road capabilities.
- Some users noted that adjusting tire pressure slightly above factory recommendations can help mitigate uneven shoulder wear, though this remains a recurring complaint across various models.

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.
