Seam 245/40 R20 99Y Jupiter 2024

Seam Jupiter 245/40 R20 99Y is a performance-oriented passenger car tyre designed for responsive steering, stable high-speed handling, dry-road grip and controlled wet-road performance. This configuration uses a 245 mm section width, 40-series profile and 20-inch rim, with a 99Y service description. Load index 99 corresponds to a maximum load of 775 kg per tyre, while the Y speed rating allows speeds up to 300 km/h under the specified operating conditions.

About Seam Jupiter 245/40 R20 99Y

The Jupiter is designed for vehicles requiring a low-profile 20-inch performance fitment. Its 245 mm footprint and 40-series profile are intended to provide a balance of steering precision, road stability and sporty handling for everyday paved-road driving.

Tread Design and Steering Response

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

Dry-Road Handling and Cornering

The 245 mm section width provides a broad contact area for dry-road grip, while the low-profile 40-series construction helps limit sidewall flex and support precise steering response. This configuration is suited to performance-oriented road driving.

Wet-Road Performance

The tread pattern is designed to help evacuate water from the contact area and support 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 40-series low-profile construction prioritizes handling precision and steering response over maximum ride cushioning. Compared with higher-profile tyres, drivers may experience a firmer road feel, particularly over rough surfaces.

Seasonal Performance

A reliable seasonal classification for the exact 245/40 R20 99Y Jupiter 2024 configuration could not be confirmed from the available product information. Therefore, the season is listed as Not Confirmed rather than assigning an unsupported classification.

Load Capacity and Speed Rating

The 99 load index corresponds to a maximum load of 775 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 Jupiter 245/40 R20 99Y is suitable for compatible passenger cars requiring this exact fitment. It is particularly suited to drivers seeking sharp steering response, stable high-speed road behaviour, dry-road grip and a sporty low-profile driving character.
