From owners
Pros, cons & observations
Themes extracted from owner reviews across retailers and review sites — not the opinion of TireWheelGuide.
The Goodyear Assurance All Season is widely regarded as a budget-friendly, comfortable, and quiet tire suitable for daily commuting in moderate climates. While many users report excellent longevity and value, a notable segment of the user base experiences significant premature tread wear and subpar performance in heavy snow or icy conditions.
Pros
- High level of ride comfort and low road noise
- Excellent value for the price point
- Reliable dry and wet weather traction for non-aggressive drivers
- Strong tread life for many users, with some reporting over 60,000 miles
Cons
- Inconsistent tread life, with reports of premature wear well before the warranty limit
- Poor performance in winter conditions, specifically on ice and deep snow
- Occasional reports of vibration and balance issues immediately after installation
- Reduced traction during heavy rain compared to premium alternatives
Observations
- Users on mid-size SUVs like the Toyota RAV4 and Honda CR-V generally report high satisfaction regarding ride quality and noise levels.
- Drivers of heavier vehicles or those in mountainous, snowy regions report that the tire struggles to maintain grip, suggesting it is better suited for flat, temperate environments.
The Kumho Solus HS51 Harmony Sports presents a polarizing experience, often praised for its comfort and value in general driving, yet criticized for significant handling instability in specific applications. While some users find them to be a superb mid-range upgrade, others report a disconcerting 'jelly-like' sidewall flex that severely compromises steering precision and dry grip.
Pros
- High level of ride comfort and low noise levels
- Excellent value for money compared to premium brands
- Strong wet weather performance
- Improved handling characteristics for van applications
Cons
- Excessive sidewall softness leading to a 'wobbling' or unstable sensation
- Noticeable decline in grip levels before the tread is fully worn
- Inconsistent handling performance depending on axle placement
- Limited durability under spirited driving conditions
Observations
- Lightweight vehicles, such as the Mazda MX-5, appear particularly sensitive to the tire's soft sidewall, resulting in reported handling instability.
- Users noted that the tire's performance characteristics are highly dependent on axle placement, with some experiencing 'dead' steering or lurching depending on front versus rear fitment.
- The tire is reported to perform well in van applications, specifically benefiting from higher load and speed ratings compared to competitors.

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.
