From owners
Pros, cons & observations
Themes extracted from owner reviews across retailers and review sites — not the opinion of TireWheelGuide.
The Kumho Solus KH21 receives a mixed reception, with users divided between those who appreciate its value and durability for daily commuting and those who find its performance lacking under spirited driving conditions. While some drivers report satisfactory grip in varied weather, others highlight significant concerns regarding wet-weather traction and audible noise levels as the tire ages.
Pros
- Competitive price point compared to premium alternatives
- Acceptable dry and wet grip for standard, non-aggressive driving
- Decent tread longevity for daily use
Cons
- Significant loss of wet-weather performance after initial wear
- High levels of road noise and audible squealing during cornering
- Inconsistent grip levels on varying asphalt surfaces
- Noticeably stiff ride quality during the initial break-in period
Observations
- Users driving older, economy-focused vehicles like the Renault Scenic reported satisfactory performance for standard commuting needs.
- Drivers transitioning from premium all-season tires noted a firmer ride quality and increased noise levels.
The Yokohama Avid Ascend is widely regarded as a high-value, all-season tire that excels in wet weather performance and ride comfort. While most users report significant improvements in traction and noise levels compared to factory-installed tires, a small subset of owners has raised concerns regarding premature tread wear and occasional manufacturing defects.
Pros
- Exceptional wet weather traction and hydroplaning resistance
- High value-to-performance ratio compared to premium competitors
- Smooth and quiet ride quality
- Reliable handling in light snow and slushy conditions
Cons
- Reports of premature or uneven tread wear in some instances
- Occasional noise issues on dry pavement
- Isolated reports of tires going out of round after moderate mileage
Observations
- Subaru Forester owners frequently cite these as a superior upgrade for both comfort and all-weather capability.
- Users of AWD vehicles, including the Audi A4 and Toyota Sienna, report high satisfaction with the tire's handling in mixed precipitation.
- Hybrid vehicle owners noted that the tire maintains fuel efficiency comparable to factory specifications.

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.
