Pros, cons & observations
Themes extracted from owner reviews across retailers and review sites — not the opinion of TireWheelGuide.
The Dunlop SP Sport 01 ROF (Run-On-Flat) receives mixed reviews, with users frequently praising its dry and wet handling performance and quiet cabin characteristics. However, these benefits are often overshadowed by significant concerns regarding rapid tread wear, a harsh ride quality typical of run-flat technology, and a high price point that many owners find difficult to justify.
Pros
- Strong dry and wet weather grip
- Quiet cabin noise levels
- Responsive steering feedback
- Stable high-speed handling
Cons
- Rapid and inconsistent tread wear
- Harsh, jarring ride quality over bumps
- High replacement cost
- Susceptibility to tramlining
Observations
- High-performance vehicle owners (e.g., C63s AMG) report that the tire struggles to manage high torque, leading to poor off-the-line traction.
- Users on smaller rim sizes (17-inch) frequently report issues with tramlining and torque steer, particularly on Mini models.
- Owners of luxury cruisers (e.g., Lexus SC430) appreciate the stiff sidewall for cornering stability, despite the trade-off in ride comfort.
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.
