Pros, cons & observations
Themes extracted from owner reviews across retailers and review sites — not the opinion of TireWheelGuide.
The Dunlop SP Sport FM800 is widely regarded as a high-value, mid-budget tire that punches above its weight class in terms of wet and dry grip, comfort, and noise suppression. While most users praise its performance-to-price ratio, some report inconsistent tread longevity and a decline in performance as the rubber compound hardens over time.
Pros
- Exceptional wet and dry traction
- High value for money compared to premium brands
- Low road noise and high ride comfort
- Predictable handling and progressive grip limits
Cons
- Inconsistent tread life reported by some users
- Performance degradation as the tire ages/hardens
- Not suitable for high-horsepower or aggressive track use
- Occasional reports of sidewall stiffness or lack of steering precision
Observations
- Users on smaller, lighter vehicles (e.g., VW Up, Ford Focus) report excellent handling and satisfaction.
- Drivers of high-performance or heavy vehicles (e.g., C63s AMG, Jaguar XF) noted that the tire struggles with high torque and may experience premature or uneven wear.
- Some users noted that steering feel can be perceived as vague on certain tire profiles, likely due to sidewall construction.
The Kumho Solus HS51 Harmony Sports presents a polarizing experience, often praised for its comfort and value in general driving, yet criticized for significant handling instability in specific applications. While some users find them to be a superb mid-range upgrade, others report a disconcerting 'jelly-like' sidewall flex that severely compromises steering precision and dry grip.
Pros
- High level of ride comfort and low noise levels
- Excellent value for money compared to premium brands
- Strong wet weather performance
- Improved handling characteristics for van applications
Cons
- Excessive sidewall softness leading to a 'wobbling' or unstable sensation
- Noticeable decline in grip levels before the tread is fully worn
- Inconsistent handling performance depending on axle placement
- Limited durability under spirited driving conditions
Observations
- Lightweight vehicles, such as the Mazda MX-5, appear particularly sensitive to the tire's soft sidewall, resulting in reported handling instability.
- Users noted that the tire's performance characteristics are highly dependent on axle placement, with some experiencing 'dead' steering or lurching depending on front versus rear fitment.
- The tire is reported to perform well in van applications, specifically benefiting from higher load and speed ratings compared to competitors.

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.
