HB4001CB Tires and wheels D When replacing a tire, make sure you use only the same size, circumferences, construction, brand, speed symbol and load index as the original tires listed on the tire placard. Using other sizes, circumferences or construction may result in severe mechanical damage to the drivetrain of your vehicle and may affect ride, handling, braking, speedometer/odometer calibration, and clearance between the body and tires. It also may be dangerous and lead to loss of vehicle control. D Do not use a combination of radial, belted bias or bias tires since it may cause dangerous handling characteristics and lead to an accident. D Do not let air out of warm tires to adjust pressure. Doing so will result in low tire pressure. The tires should be checked frequently for proper tire pressure, wear, and cuts. WARNING 11-38
