Comparison: Continental UltraContact vs. Michelin Primacy 4+ vs. Pirelli P ZERO PZ4 vs. Goodyear Efficientgrip 2 SUV

Wet performance is where the comparison becomes more nuanced. Both carry a full EU A wet grip label across their range, but the underlying data tells a more detailed story. The UltraContact posts a wet braking score of 85 — genuinely competitive — but its aquaplaning resistance is a clear weak point at 64.5, a score that places it behind much of its premium competition. The Primacy 4+ scores 76.9 for aquaplaning, a meaningful real-world advantage when encountering standing water at speed. Wet handling for the Michelin averages 80.2 across tests, and Michelin's EverGrip technology is specifically designed to maintain wet grip as the tyre wears — a point that matters over the tyre's long life. That said, more recent evaluations note that the Primacy 4+'s wet performance is beginning to show its age against newer designs, with some testers flagging longer wet stopping distances compared to the latest generation of rivals. Real-world owners of the Primacy 4+ largely report confident wet behaviour, though isolated aquaplaning incidents on heavily flooded surfaces have been noted.

On dry roads, the UltraContact has a genuine edge in outright braking. Its dry braking score of 91 places it among the best in its class, and testers consistently praise its balanced, composed character on dry tarmac — ADAC describing it as well-rounded with strong dry-road credentials. The Primacy 4+ scores 86.2 for dry braking, which remains competitive, and owners report precise, direct turn-in and good steering feedback. What the Michelin trades in raw braking sharpness it recovers somewhat in handling confidence — testers highlight its natural and predictable steering feel, making it easy to place accurately at all speeds. The UltraContact is the stronger emergency stopper in dry conditions; the Primacy 4+ offers a more communicative, reassuring experience in everyday dry driving.

This is comfortably the Primacy 4+'s strongest suit. Its comfort score of 86.6 and noise score of 84.1 are significantly ahead of the UltraContact's 75 in both categories. Owners upgrading to the Primacy 4+ frequently remark on the quietness and smoothness — one Mercedes E-Class driver specifically highlighted how much more refined their motorway experience became. The UltraContact is no harsh tyre, and its own owners also mention low cabin noise as a positive, but the Michelin is in a different bracket here. Rolling resistance further favours the Primacy 4+ with a score of 82.4, translating to better fuel economy in everyday use. The UltraContact counters with outstanding projected mileage — scoring 88 for longevity — meaning it may outlast many rivals even if it concedes some ground on day-to-day refinement.
