The Bridgestone EL400 02 Turanza tire is an all season, standard touring tire that is self-supporting with run flat capabilities. This tire was created as the original equipment tire for a couple Lexus models and for some Toyota models as well. The EL400 02 Turanza provides extended mobility up to 50 miles driving at speeds of up to 50mph after losing all the air pressure from the tire. This can be done in all weather conditions as well including light snow, wet and dry road conditions. The Bridgestone EL400 02 Turanza tire is made from an all season rubber compound that has been molded into a symmetric tread design. The design features straight circumferential grooves that balance wet and dry road traction while providing a comfortable ride and improving the tires resistance to hydroplaning. Internally the Bridgestone EL400 02 Turanza features dual steel belts that have been spirally wrapped with nylon for reinforcement. This provides a uniform ride quality with high speed durability. The Tires structure allows it to have support even in a puncture and after a total loss of air pressure.
