CHASSIS High tire pressure produces a harsh ride, handling problems, excessive wear at the center of the tire tread, and a greater possibility of tire damage from road hazards. The following instructions for checking tire pressure should be observed: D The pressure should be checked only when the tires are cold. If your vehicle has been parked for at least 3 hours and has not been driven for more than 1.5 km or 1 mile since, you will get an accurate cold tire pressure reading. D Always use a tire pressure gauge. The appearance of the tire can be misleading. Besides, tire pressures that are even just a few pounds off can degrade handling and ride. D Do not bleed or reduce tire pressure after driving. It is normal for the tire pressure to be higher after driving. D Never exceed the vehicle capacity weight. The passengers and luggage weight should be located so that the vehicle is balanced. D Be sure to reinstall the tire valve caps. Without the valve caps, dirt or moisture could get into the valve core and cause air leakage. If the caps have been lost, have new ones put on as soon as possible. 431
