Performance Analysis

Across eight summer UHP tests, the Kumho Ecsta PS91 delivers mid-pack to lower-mid results with one standout early showing. It shows occasional competence in dry braking/handling and aquaplaning resistance, plus notably low external noise and aggressive pricing in some sizes. However, persistent deficits in wet braking/handling and efficiency (rolling resistance) hold it back, keeping average overall positions around 7th.
Overall, the PS91's performance skews toward acceptable dry-road capability with comfort/noise benefits, but it struggles to convert that into strong overall placings due to recurrent wet grip shortfalls and high rolling resistance, especially in later tests with tougher competition.
