Product description & features
Michelin have developed the Primacy 4 ST DT Acoustic as a summer car tyre focused on comfort and efficiency.
It includes Acoustic technology to reduce noise and is available with reinforced (XL) options for higher load capacity.
Available in a 19" fitment; reinforced (XL) variants are offered.
The Primacy 4 ST DT Acoustic features Michelin’s Acoustic design intended to dampen tyre-cavity and road noise. This contributes to the tyre’s measured external noise level of 70 dB and helps reduce interior sound. The result is a quieter cabin and improved ride comfort.
Tyre-label ratings show a wet grip of B and a fuel efficiency rating of A, reflecting the tyre’s compound and tread design.
That combination is intended to provide reliable wet-road braking performance while limiting rolling resistance. This supports safer wet performance without compromising fuel efficiency.
Some variants of this model are offered as reinforced (XL), allowing higher load capacity for heavier vehicles.
The Primacy 4 ST DT Acoustic has also been fitted as original equipment on certain Polestar vehicles. Reinforced construction ensures compatibility with vehicles that require higher load ratings.
The Michelin Primacy 4 ST DT Acoustic - 245/45 R19 V is a summer tyre.
