About Seam Premium Plus 275/30 R21 98Y

The Premium Plus is a performance-oriented road tyre designed for vehicles requiring a wide, ultra-low-profile 21-inch fitment. Its 275 mm footprint provides a broad road contact area, while the 30-series profile is intended to support precise steering response and stable cornering.

Tread Design and Steering Response

The road-oriented tread is designed to maintain consistent contact with the road and provide predictable steering response. The wide footprint supports directional stability during acceleration, lane changes and highway driving.

Dry-Road Handling and Cornering

The 275 mm section width provides a broad contact area for dry-road grip and cornering stability. The 30-series profile helps limit sidewall flex and supports a sharper steering response, making this configuration suitable for performance-focused paved-road driving.

Wet-Road Performance

The tread design is intended to help channel water away from the contact area and maintain predictable handling on wet paved roads. Actual wet-road grip and braking performance depend on tyre condition, inflation pressure, temperature, road surface and vehicle setup.

Comfort and Everyday Driving

The 30-series ultra-low-profile construction prioritizes steering precision and handling response over maximum ride cushioning. Compared with higher-profile tyres, the ride may feel firmer over potholes and uneven road surfaces.

Seasonal Performance

The Premium Plus is classified as a summer tyre and is intended primarily for paved-road driving in warm and moderate conditions. It is not a dedicated winter tyre.

Load Capacity and Speed Rating

The 98 load index corresponds to a maximum load of 750 kg per tyre. The Y speed rating corresponds to a maximum rated speed of 300 km/h, subject to the applicable load, inflation pressure and vehicle manufacturer's requirements.

Who Should Consider This Tyre?

Seam Premium Plus 275/30 R21 98Y is suitable for compatible passenger cars requiring this exact fitment. It is particularly suited to drivers seeking sharp steering response, stable cornering, strong dry-road grip and controlled wet-road performance from a low-profile 21-inch tyre.
