The metric term for the inflation pressure is the kilopascal (kPa). The tire pressure is printed in both the kPa and the psi. One psi = 6.9 kPa. Refer to the All Seasons Tires Description or refer to Tire and Wheel Specifications for the tire inflation pressures.
The pressure recommended for this vehicle is carefully calculated to provide the following conditions:
• | To provide a comfortable ride. |
• | To provide responsive steering. |
• | To provide minimal tread wear. |
• | To provide resistance to damage from road impacts. |
The inflation pressure affects the tread profile shape and affects the contact pressure across the tread surface.
Check the tire pressure monthly with the tires cold (tires are considered cold after the vehicle has set for three hours or more or the vehicle was driven less than one mile). Check the tire pressure before an extended trip. Refer to the tire placard located on the rear face of the driver's door to set the tire air pressure to the proper specifications or refer to Specifications in this section for the proper tire air pressure specifications. The tire pressure increases about 6.9 kPa (1 psi) for every 5.5°C (10°F) temperature increase.
It is imperative to make sure the tire pressure is adequate to support the vehicle load. Check the vehicle's placard to determine the proper inflation pressures/load index.
Ensure the tire pressures are never below the minimum or never above the maximum recommended for a specific tire in normal driving conditions. A reduction in inflation pressure equals a reduction in the load-carrying capacity of the tire.
Install valve stem caps or install extensions on the valve stems to keep out dust and water.
