154 STARTING AND OPERATING 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. Underinflation also increases tire rolling resistance and results in higher fuel consumption. 3. Ride Comfort And Vehicle Stability Proper tire inflation contributes to a comfortable ride. Overinflation produces a jarring and uncomfortable ride. Tire Inflation Pressures The proper cold tire inflation pressure for passenger cars is listed on the face of the driver's door latch pillar. The pressure should be checked and adjusted as well as inspecting for signs of tire wear or visible damage at least once a month. Use a good quality pocket-type gauge to check tire pressure. Do not make a visual judgement when determining proper inflation. Radial tires may look properly inflated even when they are underinflated.
