336 MAINTENANCE wet pavement as measured under controlled conditions on specified government tests surfaces of asphalt and concrete. A tire marked C may have poor traction performance. Temperature The temperature grades are A (the highest), B, and C, representing the tire's resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to 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. Tire inflation pressures Proper tire inflation pressure is essential to the safe and satisfactory operation of your vehicle. Three primary areas are affected by improper tire pressure: 1. Safety Under-inflation increases tire flexing and can result in tire failure. Over-inflation results in a tire losing its ability to cushion shock. Objects on the road and potholes could cause tire damage that may result in tire failure. 2. Economy Improper inflation pressures can cause uneven wear patterns to develop across the tire tread. These abnormal wear patterns will reduce tread life, resulting in a need for earlier tire replacement. Under-inflation also increases tire rolling resistance and results in higher fuel consumption. 3. Ride comfort and vehicle stability Proper tire inflation pressures contribute to the excellent ride quality built into your vehicle. Over-inflation produces an uncomfortable and jarring ride. Under-inflation can produce a feeling of sluggish response. Unequal inflation pressures can produce erratic and unpredictable vehicle response to steering maneuvers. The proper tire pressure for your vehicle is listed on a placard attached near the door sill striker on the driver's
