Bridgestone Turanza EL400 RFT. FEATURES AND BENEFITS: All season drive; Run flat model; Quiet performance; Upgraded handling; . OVERVIEW: The Bridgestone Turanza EL400 RFT is a touring, all season tire manufactured for passenger vehicles.This model benefits from its ideal tread pattern and stabilized footprint to provide a noise-free and comfortable performance. The tire is able to maintain a consistent contact with the road surface, allowing the tread to absorb the vibrations generated during the drive. It also prevents the airwaves from coming into contact with tread elements, enabling the passengers to enjoy a quiet and comfortable driving experience.The reinforced sidewalls enable the tire to perform at a limited performance in case air leaves the tire due to damage. The model is still able to perform at 50 mph for 50 miles, as strong sidewall structure prevents the tire from going completely flat. This allows the driver to take the vehicle to the nearest location and safely fix or change the tire. The run flat models are heavier due to their strengthened sidewall structure, and they should not be mounted on the same vehicle together with the regular ones.The symmetric ribbed tread elements enhance the overall performance by maximizing the surface contact while tires are in motion. The detailed tread ribs with sipe placement enhance the steering response time and accuracy to the driver's commands. The structure is secured against the driving pressure against the driving pressure. It improves the overall maneuvering ability as it enables the driver to confidently control the vehicle while tires are in motion.The Bridgestone Turanza EL400 RFT's strong all season compound and detailed tread ribs boost the overall year round performing ability. The tire is able to perform remarkably well on dry, wet, and snowy road conditions. The compound keeps the rubber flexible during the performance. The circumferential grooves prevent the risk of hydroplaning by eliminating water and slush from the footprint. This maximizes the driving surface contact and promotes a safer year round performing ability. 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.
