Bridgestone Potenza RE97AS. FEATURES AND BENEFITS: All weather traction; Longer lasting tread life; Fuel efficient tire; High speed controllability; . OVERVIEW: The Bridgestone Potenza RE97AS is a performance and high performance, all season tire manufactured for passenger vehicles. Bridgestone offers a 45,000 mile treadwear warranty with the W speed rated sizes and a 55,000 mile treadwear warranty with the V speed rated sizes of this tire model.This model has exceptional all weather traction as it grips the road excellently in dry, wet and even winter conditions. The tire compound does not lose its traction in the colder winter temperatures and it provides safety in all types of seasonal weather. The tread design, with the circumferential grooves, helps resist dangerous hydroplaning situations by eliminating water from under the tire's footprint.The model's steel belt reinforcement in the internal structure help lower the rolling resistance. The reduced rolling resistance lowers the vehicle's fuel consumption and CO2 emissions, and, at the same time, it slows down the tread wear rate. The tread wears out evenly, as the driving force is equally distributed along the tread area. This is made possible with the special tire compound used in the manufacture and with the maximized road contact area of the tire. The slower tread wear rate and the even wear of the tire make it usable for a longer period of time. The tire becomes more cost efficient and environmentally friendly in this way.The Potenza RE97AS provides great high speed performance. Firstly, its handling is effortless and its steering responsiveness is swift and accurate. This is made possible with the enlarged road contact patch of the tire. The tire is easy to steer and control as it maintains constant road contact. Secondly, the tire's special shape offers a better and more stable balance during high speed performance. This makes the tire safer to use at such speeds and it increases its high speed performing capability, as the tire does not lose is shape or balance. 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.
