Ranked #6 of 10
Securing the 6th place among 10 competitors, the Nokian Powerproof tire was recognized with a 'Good' rating, underlining its suitability for daily use across all summer weather conditions, with the only notable shortfalls arising during heavy rain. Testers praised the tire for its neutral to understeering behavior, which remained driver-active with reserves in wet conditions, making it spontaneous, precise, and easy to control in dry turns. However, they noted deficiencies in aquaplaning safety and reported a faint, singing noise during handling. A standout feature of the Nokian Powerproof was its dry steering response, where it performed exceptionally well, setting a benchmark in this discipline. This balance of characteristics makes it a commendable choice for a wide range of summer driving conditions, despite its vulnerabilities in extremely wet weather.
