Passenger Car Radial Tires

SW81
Greater Grip for Enhanced Safety
The interlocking 3D sipes enhance grip on both dry and wet surfaces, making this tire an ideal choice for SUVs.
Layered Lower-Sidewall Tread Design
This feature allows the tire to cut through snow and ice to enhance control on snowy surfaces, while also expanding the lateral contact patch to improve side-biting traction.
Interlocking 3D Zigzag Sipes
3D zigzag sipes integrated into the tread blocks interlock during acceleration and braking, maintaining optimal block rigidity and enhancing grip on both dry and wet surfaces.
Grid-Pattern Main Grooves with Diagonal Z-Channels
The grid-pattern main grooves rapidly evacuate water and snow, thereby enhancing aquaplaning resistance and effectively shortening braking distances on ice and snow. Diagonal Z-channels added to the central ribs improve straight-line stability while boosting traction and handling on icy and snowy surfaces.
