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 Firestone TZ300A is generally regarded as a reliable, value-oriented summer tire that offers a strong balance of longevity and dry-weather performance. While many users praise its durability and comfort, opinions are polarized regarding road noise and wet-weather handling, with some drivers experiencing significant noise issues or inconsistent grip in challenging conditions.
Pros
- Excellent tread life and overall longevity
- Strong dry-weather grip and handling
- High value-for-money proposition
- Comfortable ride quality on various road surfaces
Cons
- Inconsistent road noise levels, with some users reporting intrusive drone
- Variable wet-weather performance and occasional aquaplaning concerns
- Lack of steering feedback or 'wallowy' feel on certain vehicle setups
- Poor performance in freezing temperatures or heavy snow
Observations
- Users with heavier vehicles (e.g., Citroen C4 Grand Picasso) noted occasional skittishness during acceleration on damp surfaces.
- Drivers of smaller, lighter vehicles (e.g., Fiat Panda) reported excellent torque management and comfort.
- Some users noted that the tire's handling characteristics can feel 'wallowy' at higher speeds on secondary country roads.

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.
