Autobild Summer tyre test 2024 265/35 R19 satisfactory Ranked #6 of 7The Goodyear Eagle F1 Supersport secured the 6th position out of 7 participants, earning a final rating of 'Satisfactory'. It was lauded for its dynamic sporting talent and the sharp, direct steering it provided on dry roads, which, along with good comfort, stood out as its best discipline. However, its performance was not without flaws. The tyre demonstrated a lack of grip and significantly understeering behavior when tested on wet surfaces, leading to extended braking distances. Furthermore, it was criticized for its high rolling resistance, which hampered its overall standing in the test. Despite these issues, its comfort level on the road was unmatched, showcasing a blend of sportiness with drivability in everyday conditions.
