BRIDGESTONE/FIRESTONE TIRE LIMITED WARRANTY W A R R A N T Y ⅷ Safety Warning Never inflate a tire unless it is secured to the vehicle or a tire-mounting machine. Inflating an unsecured tire is dangerous. If it bursts, it could be hurled into the air with explosive force resulting in serious personal injury or death. Tips for Safe Tire Inflation ⅷ ⅷ ⅷ ⅷ Check your tire air pressure, including your spare tire, at least once a week and before long trips. Be sure to use an accurate pressure gauge. Check your air pressure when the tires are "cold." The tires are cold when your vehicle has been driven less than a mile at moderate speed or stopped for at least three hours. If you must add air when your tires are hot, add four pounds per square inch (psi) (28kPa) above the recommended cold air pressure. Recheck the inflation pressure when the tire is cold. ⅷ ⅷ Never release air from a hot tire to achieve the recommended cold tire pressure. Normal driving causes tires to run hotter and air pressure to increase. If you release air while your tires are hot, you may dangerously underinflate your tires. If your tires lose more than two pounds per square inch (psi) (14kPa) of air pressure per month, the tire, valve or wheel may be damaged. Consult your Bridgestone/Firestone tire dealer for a free inspection. Check your spare tire. Consult your vehicle owner's manual for the correct inflation and use of a temporary-use spare tire. Use valve caps to keep valve cores clean and clear of debris, and to help guard against air leakage. 40 Y o u r W a r r a n t i e s i n D e t a i l
