Bridgestone B380 RFT. FEATURES AND BENEFITS: All weather traction; Run flat tire model; Comfortable driving experience; Enhanced controllability; . OVERVIEW: The Bridgestone B380 RFT is a touring, all season tire manufactured for passenger vehicles.The tire is a run flat model. It features a rayon cord body and a reinforced steel belt construction which enables the tire to maintain its ideal shape under the driving pressure. This structure also enables the tire to be driven on for 50 miles up to the speed of 50 mph after air pressure loss as it withstands the weight of the vehicle and its passengers. As a result, the driver can safely arrive at a near-by location to change or fix the damaged tire. Run flat tires are made for vehicles with no space for a spare tire. They cannot be mixed with non-run flat tires.The model promotes a comfortable drive. The stronger structure keeps the model's constant road contact, enables it to closely follow the road surface and optimizes the tire shape. This combination allows the tire to absorb the shock of driving. In this manner, the road vibrations are not felt in the vehicle's cabin and they do not disturb the driving pressure of the passengers. This guarantees a highly enjoyable driving experience.The tread design and all season compound improves the model's year round performance. The symmetric ribbed tread design with the high-density siping pattern increases the grip the tire has on the road surface. The special all season compound keeps the tire's flexible traction throughout the year in various temperatures. The circumferential grooves prevent hydroplaning by dispersing water and slush from below the tire's footprint. This combination ensures the tire's safer year round performing capability.The B380 RFT upgrades its controllability with the improved road contact. The symmetric tread's constant contact with the road surface enables the tire to boost its steering responsiveness and driving stability. This results in a faster and more precise steering responsiveness and the structure's stability. The optimal shoulder tread block pattern enhances the cornering ability. The shoulder tread blocks boost the number of biting edges and increase the maneuvering capability. The better control over the tire ensures a secure drive in all conditions. 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.
