The Michelin Primacy 4 is an excellent tyre with very low fuel use and an excellent braking ability. Unfortunately the tyre has the shallowest tread depth on test, and while that's unlikely to be a wear issue for the French tyre, it did mean the tyre scored poorly in aquaplaning test, and struggled in the deeper parts of water on the wet handling lap.

Positive: Shortest dry braking by a margin, very short wet braking, good on damp grass, lowest rolling resistance by some margin.
Negative: Lowest aquaplaning resistance on test, which also cost the tyre time on the wet handling lap, average gravel traction.

Good balance of performance. No obvious flaws. Very high wear resistance.

Short braking distance on wet and dry pavement. Low noise emission. Relatively low lateral hydroplaning resistance.

Excellent tire without any prominent issues. This tire successfully combines low rolling resistance and strong wet grip, which are conflicting parameters.

Well-balanced performance. Reliable behavior without any unpleasant surprises in any conditions. Short braking distance in any conditions. Low noise emission. Low rolling resistance.

Positive: Short braking distances and good handling on dry and wet surfaces. Low rolling resistance.
Negative: Poor resistance to lateral aquaplaning. High price.

Positive: Short braking distances on dry and wet surfaces. Low fuel consumption. Good aquaplaning resistance.
Negative: Low level of comfort. Relatively low lateral stability on wet surfaces.

Best in the test - but deficiencies in the aquaplaning protection.

Positive: Top performance on wet and dry tracks, good safety reserves for aquaplaning, precise wet and dry handling, short dry braking distances. Negative: moderate traction on sand, high price.
Verdict: exemplary.

Positive: Premium tires with short wet and dry braking distances, very good economy, high mileage, good comfort.
Negative: sluggish handling on dry slopes.
Verdict: good .

Top marks on dry roads. Slight weaknesses in the wet. Top marks for wear.

Positive: High levels of comfort and low noise, very low rolling resistance, high aquaplaning resistance.
Negative: Most expensive tyre on test, relatively slow dry and wet handling laps.
The Primacy 4 is a great all round tyre, and while it doesn't excel in any category, it has relatively few flaws.

Positive: High levels of comfort and low noise, very low rolling resistance, high aquaplaning resistance.
Negative: Most expensive tyre on test, relatively slow dry and wet handling laps.
Overall: The Primacy 4 is a great all round tyre, and while it doesn't excel in any category, it has relatively few flaws.

Very balanced tire. Top grade on wet roads. Top grade in terms of wear. Good on dry roads and in terms of fuel consumption.

Well-balanced and stable performance on wet pavement. Short braking distance and crisp steering response on dry pavement. Low lateral hydroplaning resistance. High noise emission.

Great handling response and braking performance on wet pavement. Short braking distance on dry pavement. Low rolling resistance. Slightly inaccurate steering response on dry pavement.

Well-balanced performance, excellent results on wet pavement, particularly in terms of handling and braking, great results on dry pavement.

Unexpected results for Michelin that almost turned back the time when it was launching a fuel-efficient tire with average grip on wet pavement

Short dry braking, easy to manage. Poor wet grip, average aquaplaning resistance.

Primacy 4 is slowing down on a wet road, and it is running late on the right track. The braking distance on the dry road also collects well with points. Michelin performs weaker when the road fluctuates and has poorer side grips than its competitors both wet and dry. But it is safe and easy to drive around the grip limit.

Good aquaplaning resistance. Relatively weak in the wet, slightly weak on dry roads, high purchase price.

Good results in the dry and wet, very low rolling resistance.
