The Toyo Observe Gsi-5 is a studless winter tire specially designed for drivers who require superior traction, longer wear life, and dependable performance. Ideal for light trucks, SUVs, CUVs, and vans, the Toyo Observe Gsi-5 gives you the confidence to handle all winter conditions. It features an advanced tread compound which improves its braking, traction, and wet grip at low temperatures. For slush covered roads, there are the wide lateral grooves which evacuate it efficiently so the tire maintains grip. The microbit technology enhances the tire s traction as the ground walnut shell digs and buts into ice and snow. The absorbent carbonic powder which is created from bamboo absorbs moisture from the surface so the tire maintains better contact with the road. To ensure straight-line stability and ice traction in all directions is the center rib design. The Toyo Observe Gsi-5 is branded with the Mountain Snowflake symbol which means it has passed the industry s standards for severe snow performance.
