Pros, cons & observations
Themes extracted from owner reviews across retailers and review sites — not the opinion of TireWheelGuide.
The Dunlop Roadsmart is highly regarded as a reliable, confidence-inspiring sport-touring tire that balances neutral handling with impressive wet and dry grip. While some users report uneven wear patterns or squaring off over time, the consensus highlights its significant performance improvements over older tire generations and its ability to maintain stability across varied riding conditions.
Pros
- Excellent grip in both wet and dry conditions
- Neutral and predictable steering characteristics
- High level of rider confidence during cornering
- Strong performance even when tires are cold
- Good longevity for a sport-touring compound
Cons
- Tendency for the rear tire to square off with mileage
- Soft shoulder rubber may wear faster than the center
- Occasional reports of rear wheel slippage in wet conditions for some riders
- Less dry-grip feedback compared to dedicated sport-focused tires
Observations
- High-torque bikes like the Aprilia Tuono 1000 and Suzuki Hayabusa demonstrate that the tire holds up well under aggressive, high-performance riding.
- Users transitioning from older sport-touring models (e.g., BT-020) report a transformative improvement in handling and confidence.
The Pirelli Diablo Rosso III is widely regarded as a high-performance sport tire that excels in providing predictable grip, excellent feedback, and confidence-inspiring wet-weather handling. While users consistently praise its agility and performance on twisty roads, there is a notable divide regarding tread longevity, with some riders experiencing rapid wear compared to more specialized track-focused or touring alternatives.
Pros
- Exceptional dry grip and predictable handling at various lean angles
- Improved wet-weather performance compared to more aggressive track-oriented tires
- Fast warm-up times providing immediate confidence
- High level of rider feedback and stability under heavy braking
Cons
- Inconsistent tread life, with some users reporting premature rear tire wear
- Potential for rapid degradation under aggressive riding styles
- Isolated reports of structural issues such as delamination
Observations
- Sportbike riders (Ducati 959 Panigale, Yamaha R1) report high satisfaction with the tire's ability to handle aggressive cornering and track-day usage.
- Users transitioning from touring-oriented tires (e.g., Scorpion Trail) to the Rosso III note a significant increase in agility and cornering capability, though at the expense of touring longevity.

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.
