very good
Ranked #5 of 10
Securing the 5th place out of 10 competitors, the Bridgestone Potenza Sport made a notable impression with its performance, earning a "Very good" final rating. This tire was celebrated for its exceptional cornering grip on both wet and dry surfaces, alongside precise handling characteristics that underscore its sporty nature. However, it didn't escape criticism; longer braking distances on wet surfaces were noted, and it was found to be sensitive to temperature variations. Additionally, its higher rolling resistance and the louder noise level during drive-by were points of concern, along with a somewhat rough ride. Despite these drawbacks, the tire excelled in several key disciplines, standing out as the best in aquaplaning - cross, dry handling, dry lane changing, dry steering response, wet handling, objective wet handling, and wet side guide, showcasing its strong performance across a diverse range of conditions.
