Bridgestone Dueler H/T 685. FEATURES AND BENEFITS: All weather traction; Enhanced load carrying ability; Longer lasting tread life; Improved controllability; . OVERVIEW: The Bridgestone Dueler H/T 685 is a highway terrain all season tire manufactured for sport utility vehicles and light trucks. Bridgestone offers a 50,000 mile treadwear warranty with this model.The tire offers a safer year round performance. The optimized tread design with the added sipes, the larger road contact patch and the all season tire compound firmly grip the road surface in dry, wet and winter weather. The stronger tire compound does not lose its traction in colder temperatures, while the tread elements keep their firm grip even when driving on snow and ice. The four wide circumferential grooves, the smaller lateral grooves and the high siping density prevent hydroplaning by eliminating water and slush from below the tire's footprint. The result is a more secure all weather traction.The model's internal structure features two heavy duty steel belts and a 2 ply polyester construction. They enhance the tire's strength and prevent it from deforming under the driving pressure affecting the tire. This also increases the model's durability and with it its load carrying capability. The tire does not deform under the load pressure affecting the tire during the drive, which boosts the model's load carrying and towing ability. The maintained tire shape allows the tire to closely follow the road surface in all weather, lowering the road vibrations felt in the vehicle's cabin. The lower levels of vibrations guarantee a comfortable drive, while the stronger tire structure ensures a safer driving experience.The Dueler H/T 685 features an optimized tire footprint that maintains road contact at all times. The better road contact patch firmly grips the road surface, boosting the tire's controllability. The steering responsiveness and the driving stability get upgraded as the ribbed tread design keeps its contact with the road. This stabilizes the tire against the driving pressure affecting it, while the steering becomes quick and precise in its responsiveness to the driver's commands. The optimized footprint also evenly distributes the driving pressure along the tread area. The equally spread out forces of acceleration, cornering and braking prevent irregular wear formations across the tread area, extending the tread life and the tire's usability. 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.
