Themes extracted from owner reviews across retailers and review sites — not the opinion of TireWheelGuide.
The Sumitomo H/TR Z III is widely regarded as a high-value performance tire that offers a compelling balance of dry grip, comfort, and affordability. While it is frequently praised as a cost-effective alternative to premium brands for daily driving and spirited street use, some users note limitations in extreme wet-weather cornering and high-horsepower traction.
The Yokohama Advan Sport AS is generally regarded as a competent, budget-friendly performance tire that excels in comfort and dry-road handling. While many users appreciate the value proposition and smooth ride quality, there is a notable divide regarding tread longevity and wet-weather performance, with some users reporting premature wear and stability concerns.

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.
