The Firestone Firehawk SZ90 receives highly polarized feedback, with users divided between those who find it a capable, high-grip performer and those who report significant issues with noise, uneven wear, and unpredictable handling. While some drivers praise its wet and dry traction, others cite concerns regarding stability and rapid tread degradation, suggesting inconsistent quality control or performance variability across different vehicle applications.

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.
