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

What owners like and dislike
Themes extracted from 168 owner reviews found online.
The Sumitomo H/TR Z5 receives generally favorable reviews from budget-conscious drivers seeking a capable performance tire without a premium price tag. Users frequently praise its impressive dry grip, low road noise, and comfortable ride quality compared to more expensive alternatives. However, some drivers report accelerated tread wear—particularly on the rear wheels of high-horsepower or staggered-setup vehicles—and occasional complaints regarding soft sidewalls or stability during aggressive cornering.
Pros
- Excellent value and significantly lower price point compared to premium brands
- Low road noise and comfortable ride quality
- Strong dry traction and responsive steering feel
- Improved wet weather performance over predecessor models
Cons
- Rapid tread wear, especially on rear tires of high-horsepower or staggered setups
- Softer sidewalls leading to a slight delay or spongy feel in sharp cornering
- Required break-in period where tires can feel loose or squirrelly
- Inconsistent high-speed stability reported by a minority of users
Worth knowing
- Frequently used on rear-wheel-drive sports cars and muscle cars like Mustangs, Porsches, and Corvettes, where staggered fitments prevent traditional tire rotation.
- Drivers with high-horsepower applications noted that rear tires wear out noticeably faster, with some requiring replacement significantly earlier than the fronts.
