This tire stands out as a powerful new version of the all-rounder, not just for its cost-efficiency but also due to leveraging Bridgestone's Enliten technology, enhancing its appeal. Despite a slight hesitance in directional changes on wet surfaces, it compensates with solid feedback. It remarkably resisted aquaplaning better than all rivals in the longitudinal tests, showcasing moderate understeer near its grip limit but maintaining commendable stability against load changes. On dry surfaces, while reaching its limits fairly early during aggressive driving, it remained easy to control without any unpleasant surprises, achieving the second-best result in the rolling resistance test. This performance reinforces the Roadhawk 2 as an affordable and recommendable option for drivers.
