From owners
Pros, cons & observations
Themes extracted from owner reviews across retailers and review sites — not the opinion of TireWheelGuide.
The Dunlop Grandtrek M/T2 receives a poor reception from fleet operators, primarily due to significant durability concerns and premature wear. While the tire offers acceptable on-road handling, its susceptibility to sidewall damage and structural integrity issues makes it unsuitable for demanding off-road or commercial applications.
Pros
- Acceptable on-road driving characteristics
Cons
- High levels of road noise on tarmac
- Rapid tread wear compared to competitors
- Poor sidewall durability and vulnerability to cuts
- Structural issues including sidewall rippling
Observations
- Commercial safari fleet operators report that the tire fails to meet durability requirements for heavy-duty off-road use.
The Toyo Open Country M/T is widely regarded as a premium, high-performance mud-terrain tire that balances aggressive off-road capability with surprisingly refined on-road manners. While users frequently praise its exceptional durability, puncture resistance, and longevity, some note that its heavy construction can impact fuel economy and ride comfort on pavement.
Pros
- Exceptional off-road traction in mud, dirt, and gravel
- Impressive tread life and durability for a mud-terrain tire
- Surprisingly low road noise compared to competitors
- Strong, puncture-resistant sidewalls
- Reliable performance in snow and wet conditions
Cons
- High price point compared to other options
- Significant weight can negatively impact fuel economy
- Stiff ride quality, particularly on lighter vehicles or when overinflated
- Occasional reports of balancing issues or vibrations
- Reduced traction on ice
Observations
- Heavy-duty diesel truck owners frequently report excellent longevity and load-carrying stability, often citing 50k-60k+ mile tread life.
- Jeep and light-duty truck owners note that the tire's stiff sidewalls can make for a 'harsh' ride unless tire pressure is adjusted specifically for daily driving.
- Users running larger sizes (37-inch+) emphasize the importance of regular 5,000-mile rotations to prevent uneven wear and maintain ride quality.

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.
