Ranked #8 of 8
Securing the last place among eight contenders, the Michelin Primacy 4+ certainly had a mixed performance. Despite its position, it managed to earn a 'Good' final rating, highlighting a complex evaluation. This tyre exhibited significantly short braking distances and responsive handling on dry asphalt, marking its strengths. However, it faced criticism for its long braking distances on wet surfaces, alongside weak cornering grip and poor traction under the same conditions. Concerns were also raised regarding its aquaplaning protection and an increased risk of oversteer during rapid lane changes and load transfer situations on dry roads. Interestingly, the tyre shined in terms of rolling resistance, having the best performance in this category, suggesting an impressive efficiency that unfortunately came at the expense of safety features.
