Yokohama iceGuard iG91 is a friction winter tire for light trucks, which has been manufactured in Japan since 2014. This tire is meant to increase the safety of commercial vehicles driving down icy roads, even without anti-skid studs.

The Yokohama iceGUARD iG91 came to replace the Yokohama Proforce Studless SY01 model; the new model outperforms its predecessor thanks to a 9% more efficient ice braking. In addition, its snow braking distance became 7% shorter, the rolling resistance cut by 14%. The four wide circumferential grooves (1), thanks to their unique shape, not only serve to quickly evacuate water and melted snow from the contact area but also prevent the car from going into a skid. The uniform perimeter rigidity of the Yokohama iceGUARD iG91 tread blocks (2) prevents uneven wear, at the same time reducing noise emission. The wave-shaped sipes on the surface of the tread blocks (3) speed up the evacuation of water, at the same time enhancing the edge effect, which comes in very handy on slippery winter surfaces. The “pyramid” lamellas support the rigidity of the tread blocks during the driving, at the same time increasing the reliability of the Yokohama iceGUARD iG 91 grip on snow and ice.
