CHASSIS required by law. Warning: The temperature grade of this tire established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure. Tire selection When replacing a tire, use only the same size and construction as originally installed and with the same or greater load capacity. Using any other size or type of tire may seriously affect handling, ride, speedometer/odometer calibration, ground clearance, and clearance between the body and tires or snow chains. Do not mix radial, belted, or conventional tires on your vehicle. Do not use tires or wheels other than the manufacturer's recommended size. It can cause dangerous handling characteristics, resulting in loss of control. If you need to change from conventional tires to radial tires or vice versa, replace them as a set. 368
