How to check Cadillac STS tire pressure?

To check Cadillac STS tire pressure you will first need to determine its recommended tire pressure for the front and rear tires. Take off tire valve caps and use a tire pressure gauge to check tire inflation in every tire. Adjust Cadillac STS tire pressure to its recommended levels.

Recheck tire pressure to make sure all tires are properly inflated. Replace the valve stem caps. Make sure to check tire pressure when tires are "cold" and have not been driven for at least 3 hours. Remember that the front and rear tire pressures may differ.

What is proper tire pressure for Cadillac STS replacement tires?

What is optimal winter tire pressure for Cadillac STS?
