ADAC Summer tyre test 2021 225/50 R17
poor
Ranked #17 of 17
Finishing 17th out of 17 competitors, the Firestone Roadhawk found itself at the bottom of the rankings with a final evaluation of 'Poor'. This tyre struggled significantly on dry roads, with its performance being barely satisfactory. In warm conditions, its grip was greatly reduced, leading to challenges in maintaining control. Even more concerning was its behavior on wet surfaces, where it demonstrated below-average grip levels. Large steering angles were required to navigate the handling course, and grip often completely failed when braking or accelerating in turns. This substantial flaw in handling not only affected its overall performance but also its safety on the road. While its noise level during operation was average, and it performed relatively well in terms of fuel consumption, these positives were overshadowed by its high wear rate and poor handling, particularly on wet surfaces.
