Buick Regal: Tire Inflation Description

When You Inflate The Tires To The Recommended Inflation Pressures, The Factory-Installed Wheels And Tires Are Designed In Order To Handle Loads To The Tire's Rated Load Capacity. Incorrect Tire Pressures, Or Under-Inflated Tires, Can Cause The Following Conditions:

• Vehicle Handling Concerns
• Poor Fuel Economy
• Shortened Tire Life
• Tire Overloading

Inspect The Tire Pressure When The Following Conditions Apply:

• The Vehicle Has Been Sitting At Least 3 Hours.
• The Vehicle Has Not Been Driven For More Than 1.6 Km (1 Mi).
• The Tires Are Cool.

Inspect The Tires Monthly Or Before Any Extended Trip. Adjust The Tire Pressure To The Specifications On The Tire Placard. Install The Valve Caps Or The Extensions On The Valves. The Caps Or The Extensions 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 Pounds Per Square Inch (Psi). One Psi Equals 6.9 Kpa.
