About Seam Jupiter 255/45 R19 104W

The Jupiter is a road-oriented summer tyre designed for passenger vehicles. Its 255 mm footprint and 45-series profile provide a balance between steering response, road stability and everyday driving comfort.

Tread Design and Steering Response

The Jupiter features 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 urban driving, highway travel and normal cornering.

Dry-Road Handling and Cornering

The 255 mm footprint provides a broad contact area for stable dry-road handling, while the 45-series profile helps balance steering precision with ride comfort. The tyre is suited to drivers looking for confident and responsive paved-road performance.

Wet-Road Performance

The circumferential grooves are designed to channel water away from the contact area and support 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 45-series profile provides a practical balance between handling response and sidewall cushioning. It can offer a more compliant ride than very low-profile configurations while retaining a sporty road-oriented character.

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 104 load index corresponds to a maximum load of 900 kg per tyre. The W speed rating corresponds to a maximum rated speed of 270 km/h, subject to the applicable load, inflation pressure and vehicle manufacturer's requirements.
