From owners
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.

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.
