Features

DIRECTIONAL TREAD PATTERN A directional tread design with staggered tread blocks maximizes traction and handling while improving ride comfort by reducing road noise.

SERRATED STABILITY RIB A continuous centre rib adds stability during highway driving or when changing lanes. A unique serrated design digs into deep snow and slush for better cold weather traction.

SPLIT OFFSET SHOULDER BLOCKS Large outer blocks on the outside shoulder add stability to the tire as well as grabbing power in deep snow. The saw-tooth edges add lateral traction while cornering.

4 CIRCUMFERENTIAL GROOVES 4 circumferential grooves efficiently evacuate moisture from under the tire for better grip.

HIGH DENSITY 3D SIPES Toyoâ€™s Multi Wave 3D siping provides for more edge effect while ensuring the blocks remain firmer while braking, cornering or accelerating. This improves performance and reduces the risk of irregular wear.

FIRST EDGE SIPE A shallow initial edge sipe throughout the tire helps with traction during the tires break-in period.

TAPERED SHOULDER WEDGE A tapered buttress design along with unique outside block grooves on the sidewall adds to the tires ability to navigate slushy rutted roads.

MICROBIT TECHNOLOGY IN COMPOUND Crushed walnut shells embedded in the tire tread compound dig and bite into the ice surface for improved traction.

LARGE INNER BLOCKS WITH SAW TOOTHED EDGES Larger inner blocks add stability at highway speeds. These blocks are tied together in the GSi-6 HP model for added handling performance. While the saw-tooth edges around the block add biting grip in deep snow and slush covered roads.

SNOW CLAWS These edges within the tread grooves enhance traction in deep snow or slush.

TAPERED EVACUATION GROOVES Tapered evacuation grooves quickly move the water or slush away from the center of the tire to reduce the risk of hydroplaning or getting caught in slushy rutted roads.

SPIRAL EDGE SIPE A unique 360 degree spiral edge sipe is designed to improve traction while accelerating, cornering or braking.

SHOULDER LIGHTNING EDGE A jagged lightning style sipe in the shoulder blocks adds lateral traction when cornering.
