Comparison: Continental UltraContact vs. Michelin Primacy 4+ vs. Bridgestone Blizzak 6 vs. Michelin Primacy 5

The wet picture is more nuanced and ultimately more important for a touring tyre. Both carry an EU 'A' wet grip rating, and both produce competitive wet braking figures — the UltraContact actually scores higher in wet braking than in overall wet performance, suggesting its compound grips well in straight-line situations. But the critical differentiator is aquaplaning resistance: the Primacy 4+ scores a full twelve points higher in this category, meaning it manages standing water significantly better before losing contact. This is a real-world safety advantage on a motorway in heavy rain. However, the Primacy 4+ carries a caveat — multiple 2024 and 2025 evaluations note that its wet performance is beginning to show the tyre's age against newer designs, with longer wet stopping distances and slower wet handling times compared to the most recent competition. One owner even reported aquaplaning on the Primacy 4+, underlining that the aquaplaning scores reflect a relative rather than absolute advantage. The UltraContact's wet handling has minor noted weaknesses, but its wet braking is solid. On wet roads, the Primacy 4+ is the more rounded performer, but neither is exceptional by current UHP standards.

This is where the two tyres diverge most sharply, and where the Primacy 4+ earns its strong overall rating. Its comfort score of 86.6 against the UltraContact's 75 is a gap that is genuinely perceptible from the driver's seat — the Michelin rides more smoothly over surface imperfections and absorbs road texture in a way the Continental simply cannot match. On noise, the Primacy 4+ finishes among the quietest tyres in recent comparative tests, and owners consistently describe a serene motorway experience. UltraContact owners also report low noise — it is one of the most praised attributes in customer feedback — but the objective scores and test results confirm the Primacy 4+ is the quieter, more comfortable tyre by a measurable margin. On rolling resistance, the Michelin holds an advantage here too, with a score of 82.4 versus the UltraContact's B-rated fuel efficiency. Mileage is strong on both — the UltraContact scores slightly higher in longevity metrics, and ADAC specifically highlighted its very high projected tread life, which partially offsets its higher noise and stiffer ride.

On dry tarmac, the UltraContact is the genuine surprise of this pairing. Its dry braking score stands well above the Primacy 4+, and ADAC testing confirmed a balanced, capable character on dry surfaces with strong handling credentials. Owners on motorways report a secure, planted feel, and the tyre's EU B fuel label reflects a compound tuned with efficiency in mind without sacrificing grip. The Primacy 4+ is no slouch — AutoBild testing highlights precise turn-in, direct steering response, and short dry braking distances — but the UltraContact holds a clear points advantage in pure dry braking metrics. Where the Michelin edges ahead is in dry handling consistency and steering feel; its natural, progressive character under pressure has drawn praise from multiple independent evaluators, and real owners describe a confidence-inspiring response that makes it easy to drive smoothly at pace. For everyday dry-road safety, both are competent; for outright dry braking, the UltraContact leads.
