BRIDGESTONE/FIRESTONE TIRE LIMITED WARRANTY W A R R A N T Y Regardless of the speed and handling capabilities of your car and its tires, a loss of vehicle control can result from exceeding the maximum speed (a) allowed by law or (b) warranted by traffic, weather, vehicle or road conditions. High-speed driving should be left to trained professionals operating under controlled conditions. No tire, regardless of its design or speed rating, has unlimited capacity for speed, and a sudden tire failure can occur if a tire's speed limits are exceeded. Non-speed-rated tires are built for ordinary passenger service and should never be used for high-speed driving. Even speed-rated tires may not be driven at speeds exceeding their maximum actual speed capability. Tire Speed Ratings Some tires, especially "touring" or "performance" tires, bear a letter designating the tire's design speed capability. This speed-rating system is intended to allow you to compare the speed capabilities of tires. When purchasing or replacing speed-rated tires, make sure to: Use the rankings in the following chart to compare the speed ratings of all the tires. Follow the vehicle manufacturer's recommendations, if any, concerning the use of speed-rated tires. ⅷ ⅷ To avoid reducing the speed capability of the vehicle, replace a speed-rated tire only with another tire having at least the same speed rating. Remember, it's the "top speed" of the "slowest" tire on the car that cannot be exceeded without risk of tire failure. The letter symbols and corresponding design speeds are specified on the next page. 47 Y o u r W a r r a n t i e s i n D e t a i l
