Michelin Primacy ST Acoustic – 245/40 R20 99V XL TL is a premium touring summer tyre designed for passenger vehicles that prioritise ride comfort, low noise levels, and everyday road safety. It features a refined symmetric touring tread pattern with optimised circumferential grooves to ensure controlled water evacuation and stable wet braking performance. The integrated Michelin Acoustic technology uses a polyurethane foam layer attached to the inner liner to significantly reduce cavity noise transmitted into the vehicle cabin, improving overall driving comfort. The tread compound and block geometry are tuned for smooth rolling and even wear, while the reinforced XL construction supports higher load requirements of modern vehicles equipped with larger alloy wheels. This tyre is suitable for drivers seeking quiet, stable, and comfortable on-road performance.
