Michelin 315/30 R21 105Y Pilot Sport 4S Acoustic MO1 2024

Michelin Pilot Sport 4S Acoustic MO1 315/30 R21 105Y is an ultra-high-performance summer tyre developed for compatible high-performance passenger cars and SUVs, particularly Mercedes-Benz applications requiring the MO1 approval. This exact configuration uses a 315 mm section width, 30-series profile and 21-inch rim, with a 105Y XL service description. Load index 105 corresponds to a maximum load of 925 kg per tyre, while the Y speed rating is designed for speeds up to 300 km/h; the ZR designation identifies it as a high-speed radial tyre. Michelin lists this exact 315/30R21 105Y XL MO1 Acoustic configuration in its Pilot Sport 4 S range. :contentReference[oaicite:0]{index=0}

Tread Design and Steering Response

The Pilot Sport 4S uses a performance-oriented asymmetric tread design developed to provide precise steering response and consistent road contact. The very low 30-series profile and reinforced XL construction support direct steering feedback and stable directional control during high-performance road driving.

Dry-Road Handling and Cornering

The wide 315 mm footprint provides a substantial contact area for dry-road grip, while the low-profile construction is designed to enhance lateral stability and steering precision during cornering. The Pilot Sport 4S is engineered around high levels of dry-road grip, braking control and steering response for performance-oriented driving.

Wet-Road Performance

The tread pattern incorporates water-evacuation grooves designed to help maintain contact with wet pavement. The exact 315/30ZR21 105Y XL MO1 Acoustic configuration carries a B EU wet-grip rating, supporting its strong wet-road performance credentials. Actual wet traction and braking distances vary with temperature, tread depth, tyre pressure, road surface and vehicle setup. :contentReference[oaicite:1]{index=1}

High-Speed Stability

The 105Y specification is intended for high-performance vehicles requiring very high speed capability. The reinforced XL construction and low-profile design support stable road contact and predictable steering response during high-speed driving, subject to the vehicle manufacturer's approved tyre specifications.

Acoustic Technology and Comfort

The Acoustic version incorporates Michelin's noise-reduction technology intended to reduce tyre-generated cabin noise. Despite its very low 30-series profile and performance-focused construction, this configuration is designed to provide controlled road manners while maintaining the handling characteristics expected from the Pilot Sport 4S. Actual comfort and interior noise depend on vehicle suspension, road surface, tyre pressure and vehicle configuration.

Braking Performance

The Pilot Sport 4S is designed to deliver strong braking and traction on both dry and wet paved surfaces. Independent testing information for this exact 315/30ZR21 MO1 Acoustic configuration has highlighted short braking distances, precise turn-in and strong wet and dry handling. :contentReference[oaicite:2]{index=2}

Seasonal Performance

This Michelin Pilot Sport 4S configuration is a summer performance tyre intended for warm-weather paved-road use. It is not marked for severe snow or ice conditions and is not a substitute for a dedicated winter tyre. :contentReference[oaicite:3]{index=3}

Load Capacity and Speed Rating

The 105 load index corresponds to a maximum load of 925 kg per tyre. The Y speed rating corresponds to a maximum rated speed of 300 km/h, while the ZR designation indicates a high-speed radial construction. The exact product is specified as XL and MO1-approved for Mercedes-Benz applications. :contentReference[oaicite:4]{index=4}

Who Should Consider This Tyre?

Michelin Pilot Sport 4S Acoustic MO1 315/30 R21 105Y is suitable for compatible high-performance passenger cars and SUVs requiring this exact fitment and Mercedes-Benz MO1 approval. It is particularly suited to drivers seeking precise steering, strong dry grip, confident wet-road performance, high-speed stability and reduced tyre-generated cabin noise.
