The Firestone F580 receives highly polarized feedback from users, with experiences ranging from exceptional longevity and all-weather capability to severe dissatisfaction regarding safety and tread life. While some drivers praise the tire for its quiet operation and surprising performance in adverse conditions, others report significant concerns regarding wet-weather traction and rapid wear.
Pros
- Strong dry grip and road feedback
- Surprisingly capable performance in snow for a summer-biased tire
- Quiet and smooth ride quality
- High mileage potential for some users
Cons
- Inconsistent wet-weather traction and safety concerns
- Premature tread wear reported by some owners
- Polarizing performance reliability across different vehicle setups
Observations
- Users operating smaller, lighter vehicles like the VW Golf and Astra reported high satisfaction and long tread life.
- Performance consistency appears highly variable, suggesting the tire may be sensitive to specific vehicle chassis tuning or driving styles.

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.
