Otani SA1000 – 265/65R18 (112T) The SA1000 tire promotes excellent all weather traction. The semi-asymmetric tread design increases the dry, wet and winter weather road gripping ability thanks to the detailed siping pattern that keeps the tire?s road grip at all times. The design?s circumferential and lateral grooves prevent hydroplaning by eliminating water and slush from below the tire?s footprint. The combination of the superb hydroplaning resistance and great all weather traction ensures a comfortable driving experience in all weather.
