Maintenance and care sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law. The temperature grade for this tire is 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. SERVICING YOUR TIRES Checking the tire pressure • Use an accurate tire pressure gauge. • Check the tire pressure when tires are cold, after the vehicle has been parked for at least one hour or has been driven less than 5 km (3 miles). • Adjust tire pressure to recommended specifications found on the inflation placard. Improperly inflated tires can affect vehicle handling and can fail suddenly, possibly resulting in loss of vehicle control. 221
