Ranked #7 of 9
Finishing 7th out of 9 competitors, the Michelin Primacy 4+ demonstrated a mixed performance. The tyre is lauded for its exceptionally energy-efficient and smooth rolling characteristics, a testament to its traditional strength in minimizing rolling resistance. It excels in comfort, exterior noise reduction, and rolling resistance, outperforming all others in these areas. However, it faces criticism for its performance under dry conditions, where it tends to understeer when driven aggressively, and lacks the dynamism some might expect. Steering precision and lateral support are moderate, though the tyre's reactions are never critically negative. The most significant downside noted was its performance in wet conditions; the Michelin Primacy 4+ trades its excellent rolling resistance for subpar wet handling capabilities, including the slowest lap time and the longest braking distance in wet tests, indicating limited wet grip which ultimately hindered a stronger overall result.

Ranked #4 of 10
Securing a commendable 4th place among 10 contenders, the Michelin Primacy 4+ has been rated as 'Exemplary' for its performance. This tire stood out for its top-notch summer profile, boasting dynamically safe handling on both wet and dry roads. The precision in steering response, complemented by effective feedback and notably short braking distances on various surfaces, underscores its reliability. Additionally, its secure aquaplaning characteristics and the pleasantly quiet ride comfort it offers positively contributed to its high evaluation. One aspect noted was its high price level; however, this does not diminish its overall excellence. Of particular distinction, the tire excelled in the discipline of comfort, firmly establishing its prowess in providing a soothing driving experience without compromising safety or performance.
