Vehicle Service and Care 9-49 Inflation - Tire Pressure Tires need the correct amount of air pressure to operate effectively. Notice: Do not let anyone tell you that under-inflation or over-inflation is all right. It is not. If your tires do not have enough air (under-inflation), you can get the following: • Too much flexing • Too much heat • Tire overloading • Premature or irregular wear • Poor handling • Reduced fuel economy If your tires have too much air (over-inflation), you can get the following: • Unusual wear • Poor handling • Rough ride • Needless damage from road hazards A vehicle specific Tire and Loading Information label is attached to the vehicle's center pillar, below the driver's door latch. This label lists the vehicle's original equipment tires and the recommended cold tire inflation pressure for the tires when they are cold. The recommended cold tire inflation pressure, shown on the label, is the minimum amount of air pressure needed to support your vehicle's maximum load carrying capacity. For more information regarding how much weight your vehicle can carry, see Loading the Vehicle on page 8-30. How you load your vehicle affects vehicle handling and ride comfort. When driving with less than the maximum load capacity allowed for your vehicle, you can set tire inflation pressure to the recommended amounts shown in the following chart. Never load your vehicle with more weight than it was designed to carry.
