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

By road tests

The Sumitomo BC100 generally receives positive feedback as a capable, budget-friendly tire that offers solid performance in both wet and dry conditions for everyday driving. While most users praise its exceptional value, reliable rain dispersion, and comfortable ride, a minority report drawbacks such as increased road noise, premature wear, or unpredictable handling when pushed hard.
Pros
- Excellent value for money compared to premium brands
- Strong wet and dry grip for everyday commuting
- Good water dispersion and confidence in heavy rain
- Comfortable ride quality with favorable tread wear for most users
Cons
- Higher than average road noise reported by some drivers
- Occasional understeer or reduced grip during aggressive cornering
- Mixed experiences regarding longevity, with a few reporting faster-than-expected wear
Worth knowing
- Drivers of heavy estate cars and light vans noted adequate load handling and stable long-distance cruising, though some van drivers experienced noticeable understeer and increased cabin noise.
- Users with larger 17-inch sizes on heavier front-wheel-drive sedans reported that the tires can occasionally lose traction during rapid acceleration on imperfect road surfaces.
