Ranked #5 of 8
Securing the fifth position among eight competitors, the Firestone Winterhawk 4 earned itself a 'Good' final rating in a notable winter automotorsport event. Testers praised the tire for its easily manageable nature, impressive driving dynamics, high level of grip, and considerable reserves on snow, which made it stand out, especially in the disciplines of snow handling and lateral guidance on snow. However, the tire was not without its drawbacks; its performance was marred by weak braking capabilities, a lack of grip reserves, sensitivity to load changes on wet surfaces, an increased risk of aquaplaning, and longer braking distances on dry roads. Additionally, it was noted for generating noticeable noise while rolling, contributing to a less comfortable driving experience. Despite its dynamic prowess in snow-rich environments, the Firestone Winterhawk 4 showed significant deficits in wet and dry conditions.
