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 AS is generally regarded as a high-performance tire that excels in ride comfort, cabin quietness, and dry-weather handling. While many users praise its refined road manners and surprising capability in varied conditions, the consensus is heavily tempered by concerns regarding rapid tread wear and inconsistent performance under high-torque applications.
Pros
- Exceptional ride comfort and low noise levels
- Strong dry-weather grip and handling precision
- Surprising all-season capability, including performance in snow
- Superior longevity compared to some competing high-performance OEM tires
Cons
- Rapid tread wear, particularly on high-performance vehicles
- Poor traction and stability under high-torque, high-horsepower acceleration
- Vulnerability to sidewall damage
- High replacement cost relative to tread life
Observations
- High-horsepower vehicles, such as the C63s AMG, struggle with traction, suggesting the tire is ill-suited for extreme torque outputs.
- Owners of luxury cruisers like the Lexus SC430 appreciate the stiff sidewall construction for maintaining tracking stability and handling precision.
The Riken All Star 2 is viewed as a polarizing budget-tier tire that serves as a temporary solution rather than a long-term investment. While some users appreciate its value proposition for light-duty city driving, others report significant concerns regarding premature wear and overall durability compared to premium alternatives.
Pros
- Attractive low price point
- Acceptable noise levels for budget-conscious drivers
- Adequate stopping performance in light city conditions
Cons
- Poor tread longevity and durability
- Failure to meet safety inspection standards within a year
- Inconsistent quality compared to premium tire brands
Observations
- Users operating smaller, lighter vehicles like the Daewoo Matiz reported acceptable noise levels and curb-climbing capability.
- The tire is frequently criticized when used as a direct replacement for higher-end performance tires, highlighting a significant gap in material 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.
