Ranked #5 of 17
Securing the 5th position out of 17 contenders, the Michelin Primacy 4 was distinguished particularly for its exceptional performance on dry surfaces and remarkable durability, leading the pack in these areas. When it came to dry braking, safety, and mileage, this tire showcased superior capabilities, establishing itself as the top choice. Testers praised its shortest stopping distance on a dry road at just 35.2 meters, precise steering, highest grip levels, and the early warning it gave before losing traction, ensuring no surprises even when navigating through rapid direction changes. However, its performance slightly dipped in wet conditions, which contributed to a final rating of 'Satisfactory'. Despite delivering satisfactory stopping distances on wet roads and decent resistance to hydroplaning in corners, it couldn't match its dry conditions prowess entirely. Additionally, its fuel efficiency and noise levels were considered average, but it was significantly recognized for its low wear rate, topping the list in this regard.
