Two scoring systems, side by side
Owner scores come from reviews found online; road-test scores come from instrumented tests. Where they disagree, it is usually a discipline owners rarely push to the limit.
How scores work
- Relative score
- 0–100. Blends road tests (60%) and owner reviews (40%) category by category, the same way on every TireWheelGuide page. With only one of the two, the missing half is estimated from it, so the score stays closer to average. It needs at least one road test or five owner reviews.
- Road tests
- 0–100 per score, from published tests, newer tests counting more. Each result is compared with every other tire in the same test, so a win against a strong field counts for more. The average tested tire gets 70, the best 100; with only one or two tests a tire stays nearer 70. The discipline rows show % of the best tire in that test.
- Owner reviews
- 0–100 from the owner reviews we found online, adjusted for how generously each site rates and scaled like the road tests: the average tested tire gets 70. With only a few reviews a tire stays near the average.
By owner reviews
63/100From 980 owner reviews analysed, scaled like the road tests: the average tested tire gets 70.
By road tests
58/100Scaled across every tested tire: the average gets 70, the best 100.

The Yokohama BluEarth 4S AW21 is generally well-received as a dependable all-season tire that inspires confidence in wet, icy, and snowy conditions. While users frequently praise its robust wet-weather performance, solid winter traction, and overall value, some note drawbacks such as increased road noise and softened handling in warm summer temperatures.
Pros
- Excellent grip and stability on wet and flooded roads
- Strong traction and confidence-inspiring performance in snow and ice
- Good value for money compared to premium competitors
- Reliable all-season versatility and long-lasting durability
Cons
- Higher road noise levels ('howling' or noticeable hum) compared to some other brands
- Softer cornering feel and reduced precision during hot summer months
- Minor negative impact on fuel economy for some drivers
Worth knowing
- Owners utilizing these tires on SUVs and heavier vehicles reported solid load handling and reliable traction in muddy off-road conditions.
- Compact car drivers (such as VW Golf owners) noted great wet and dry grip during spirited driving, though some experienced minor steering feel quirks during slow maneuvers.
