Yokohama Ice Guard IG50 Plus ( 145/80 R12 74Q, Nordic Compound )

Yokohama iceGUARD studless iG50 PLUS The ultimate ice-grip with fuel-saving property. Applications Compact cars Sporty hatchbacks Benefits Extreme ice grip Fuel Saving Long-life grip Feature Super Water Absorptive Compound iG50 Asymmetric tread Triple 3-D Dimple Sipes　 Low-Heat-Generating Under Tread Anti Energy-Loss Profile Technology Tread Compound The layer of water above the ice is the biggest contributor to loss of traction. It causes ‘micro hydroplaning‘ on icy surfaces. A traditional rubber rides on the surface water because the thickness of the layer of water in the -6 to 0°C zone becomes more than the normal undulations of the tyre surface can manage to work effectively. YOKOHAMA´s original SUPER WATER-ABSORPTIVE COMPOUND technology can put the tyre in contact with the actual ice by removing water with powerful absorbent compounds. Absorptive Balloon Removes Water film from the ice surface by its cavity shape. Delivers micro edge effects on the ice surface by its hard shell. Keeps tread-block solid by its hard shell construction. Absorptive White Gel Removes water film from the ice surface by a suitable undulation for the tyre surface delivered by its flexible property. Tread Pattern and Construction Technologies Anti Energy-Loss Profile Delivers a fuel saving performance and stability by controlling a deflection of the tyre. Asymmetric Tread pattern Inner zone, an effective tread pattern area for ice performance, has more actual contact area and more sipes than outer zone in order to maximize the friction and edge effects on ice surface. Triple 3-D dimple sipes / Triple 3-D sipes 2 types of original 3-dimension shaped sipes are varied to get suitable effects and balances on each tread area. The surfaces of 3-D sipes avoid uneven deflection of blocks by supporting each other. It delivers excellent ice and snow performance with its maximized actual contact area and edge effects. Belted Blocks The belted blocks with a large, wide, centralized block improve the braking stability as well as the performance on wet, dry and icy road surfaces. Micro Diagonal Sipes Deliver optimum performance even without a break-in period. Outer zone, an effective tread area for snow performance, has more grooves in order to maximize the traction and edge effects on snow surface.
