Pros, cons & observations
Themes extracted from owner reviews across retailers and review sites — not the opinion of TireWheelGuide.
The Kumho Solus 4 All Weather provides reliable grip across various weather conditions, including wet, dry, and light snow. However, the tire suffers from significantly premature tread wear, which undermines its value proposition as a practical year-round solution.
Pros
- Reliable traction in dry conditions
- Confident performance on wet surfaces
- Effective capability in light snow
Cons
- Extremely rapid tread wear
- Poor overall longevity compared to summer tires
- Lack of cost-effectiveness due to frequent replacement intervals
Observations
- Performance and grip were noted as sufficient for lightweight vehicles like the Suzuki Ignis.
The Yokohama BluEarth 4S AW21 is generally regarded as a competent all-weather tire that excels in wet and winter conditions, providing reliable traction in cold temperatures. While users appreciate its performance in adverse weather, the tire receives mixed feedback regarding its longevity, road noise, and handling characteristics during warmer months.
Pros
- Excellent wet weather grip and stability on motorways
- Strong performance in snow and icy conditions
- Quiet and smooth ride quality during the first two years of ownership
- Aesthetically pleasing tread design
Cons
- Noticeable increase in road noise, described by some as excessive
- Soft compound feel during high-temperature summer driving
- Concerns regarding long-term durability and premature tread cracking
- Unusual steering feedback during low-speed maneuvering
Observations
- Drivers of compact hatchbacks, such as the VW Golf, report acceptable dry and wet grip but note a peculiar sensation in steering feel.
- Performance in warmer climates (30°C+) results in a 'soft' feeling during cornering, suggesting the compound is better suited for temperate or cold environments.

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.
