Toyo Observe GSi-5 Studdless Winter Tire
The directional Observe GSi-5 studless winter tire from Toyo Tire U.S.A. Corp. features Microbit studless tire technology which relies on crushed walnut shells in the compound to provide traction on icy surfaces. Increased silica provides better tread block flexibility at lower temperatures. A new obsorbent carbonic powder made from bamboo charcoal is mixed within the compound to absorb the thin water layer on top of the ice. Spider sipe technology ensures maximum grip during cornering, acceleration or braking, and saw-toothed tread block edges improve traction in snow and slush. Available in more than 90 sizes to fit 15- through 20-inch rim diameters.
