Dunlop SP Winter Sport M3 Performance Winter / Snow tires were developed for sports cars, coupes and sedans that come from the factory equipped with low profile tires mounted on large diameter alloy wheels. SP Winter Sport M3 tires are designed to blend dry road performance with cold temperature traction whether roads are snow-covered or not. The SP Winter Sport M3 features a silica-based tread compound that remains pliable in cold temperatures. Using Dunlop V-Technology, this compound is molded into a directional tread design that helps maintain good traction on wet and slush-covered roads while its high-density lateral zigzag sipes and independent tread blocks provide the edges to help bite into snow. Dunlop SP Winter Sport M3 winter / snow radials meet the industry's severe snow service requirements and are branded with the mountain/snowflake symbol. Install SP Winter Sport M3 tires in sets of four only. Do not mix radial winter / snow tires with tires of other construction, size, ply rating, or pattern type. Dunlop highly recommends fitment of four winter / snow tires of the same type and rating for optimum mud and snow traction as well as to maintain vehicle handling characteristics.
