Delta Sierradial AT4S. FEATURES AND BENEFITS: All terrain traction; All weather grip; Improved controllability; Comfortable performance; . OVERVIEW: The Delta Sierradial AT4S is an all terrain, all weather tire made for light trucks and SUVs. Delta offers a 55,000 mile treadwear warranty with this model.The model offers great on- and off-road terrain traction. The aggressive tread pattern manages to easily perform on soft, loose, and uneven terrains. The large tread elements firmly grip the road and terrain surface with extra biting edges, maintaining forward motion at all times. These elements increase the tire's overall performance, both on- and off-road terrains. On the other hand, the self-cleaning nature of the tread eliminates mud, snow, and rocks stuck between the tread elements. This ensures better contact with driving surfaces while also resisting stone retention from harming the tire's casing during the off-road ride.The aggressive tread pattern and its consistent driving surface contact improve controllability. They effectively boost steering responsiveness and driving stability. The steering response time is faster and more precise to the driver's commands, while the structure is secured against driving pressure. The wide shoulder blocks and their strong grip enhance the tire's cornering. These elements increase overall controllability and maneuvering. As a result, the driver has full control over the vehicle and guarantees a safe driving experience.Excellent all weather traction is promoted with this model. The ideal tread pattern can easily perform in dry, wet, and winter conditions. At the same time, this tread manages to handle ice- and snow-covered roads as well. The all weather compound keeps the rubber flexible in changing temperatures, from warm summer to freezing winter conditions. The model also provides great hydroplaning resistance. The optimal grooves eliminate water and slush from the footprint in wet situations.The Delta Sierradial AT4S offers a quiet and comfortable driving experience. The optimal tread pattern and the special silica compound reduce road and tread noise levels heard in the vehicle's cabin. The footprint channels airwaves through, preventing them from coming into contact with tread elements. As a result, it does not generate noise. This tread allows the passengers to enjoy a quiet performance.All weather tires receive the three mountain peak and snowflake (3PMS) symbol for their exceptional winter weather performance. They are all season tires with extra winter weather grip, in order to guarantee safer year-round durability. This ensures their true and secure driving ability throughout the year.Manufacturers recommend changing tires every 10 years. As long as tires are properly stored before they are sold, the year of their manufacture will not shorten their service life.
