Bridgestone Dueler H/L 422 Ecopia. FEATURES AND BENEFITS: All weather traction; Fuel efficient tire; Enhanced durability; Reduced road noise; Longer lasting tread; . OVERVIEW: The Bridgestone Dueler H/L 422 Ecopia is an all season touring tire made for passenger and SUV vehicles. Bridgestone offers a 65,000 mile treadwear warranty with this model.This all season tire offers excellent all weather traction, and it grips the road well in dry, wet and winter weather. Its first-rate traction is the result of the special tread pattern that grips the road well in all weather conditions. The tread design also makes the tire safer to use in wet weather conditions, as it enhances the wet traction and helps avoid hydroplaning by channeling water from below the footprint of the tire. This superb all year-round traction makes the tire more versatile.The Ecopia NanoPro-Tech reduces the tire's rolling resistance by lowering the overall weight of the model. The lessened rolling resistance reduces fuel consumption and CO2 emissions from the vehicle. The tire is more environmentally friendly in this manner and it is more cost efficient as well. The lower rolling resistance also helps slow the tread wear rate down. This, along with the equally distributed driving force along the tread area, extends the tire's life. The even distribution of the driving pressure prevents irregular wear on the tires, making it more cost efficient.The reinforced internal structure of the tire enhanced its performance. Its performing durability is increased, which allows high speed driving. The tire maintains its shape under the driving pressure and since it does not deform it is safer to use in those situations. The stronger structure also improves the comfort levels of the model. The tire absorbs the shock of driving and reduces the vibrations felt in the cabin of the vehicle, offering a more comfortable driving experience.The Dueler H/L 422 Ecopia's continuous center rib channels the air waves through the footprint and helps reduce road noise while driving. The total road noise levels are decreased, providing a quieter and more enjoyable drive. 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.
