Inflation Pressure
When you inflate the tires to the recommended inflation pressures, the factory-installed wheels and tires are designed to handle loads to the tire's rated load capacity. Incorrect tire pressures, or under-inflated tires, can cause the following conditions:^ Vehicle handling problems
^ Poor fuel economy
^ Shortened tire life
^ Tire overloading
Check the tire pressure when the following apply:
^ The tires are cool.
^ The vehicle has not been driven for more than 3 hours.
^ The vehicle has been driven less than 1.6 km (1 ml).
Check the tires monthly or before any extended trip. Adjust the tire pressure to the specifications on the tire label. Install the valve caps or extensions on the valves. These keep out dust and water.
The kilopascal (kPa) is the metric term for pressure. The tire pressure may be printed in both kilopascal (kPa) and psi. One psi equals 6.9 kPa.
