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:

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.
