About Seam Jupiter 255/40 R19 100Y

The Jupiter is a road-focused summer tyre designed for passenger vehicles. Its 255 mm footprint and 40-series low-profile construction are intended to provide a balance of steering precision, road stability and sporty driving response.

Tread Design and Steering Response

The Jupiter uses a symmetric road-oriented tread pattern with circumferential grooves designed to support consistent road contact and efficient water evacuation. The tread layout is intended to provide predictable steering response during everyday driving and highway manoeuvres.

Dry-Road Handling and Cornering

The 255 mm footprint provides a broad contact area for dry-road stability, while the 40-series profile helps reduce sidewall flex and support precise steering response. This configuration is well suited to drivers looking for a responsive and sporty road feel.

Wet-Road Performance

The circumferential grooves are designed to channel water away from the contact area and support predictable wet-road control. Actual wet-road grip and braking performance depend on tyre condition, inflation pressure, temperature, road surface and vehicle setup.

Comfort and Everyday Driving

The 40-series low-profile construction prioritizes steering precision and handling response over maximum ride cushioning. Compared with higher-profile tyres, the ride may feel firmer over rough or uneven surfaces.

Seasonal Performance

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

Load Capacity and Speed Rating

The 100 load index corresponds to a maximum load of 800 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.
