I removed my back tires today to install my mud flaps and was just wondering, I didn't see anything???
I found this;
General Tire Pressure Information
Using data retrieved from your Tire Pressure Monitoring System, we'll let you know in your OnStar Vehicle Diagnostics* report if your tire pressure needs attention. You should check your tires monthly, at a time when you haven't driven for at least three hours.
* What is the Tire Pressure Monitoring System and how does it work?
Tire Pressure Monitoring System — If your vehicle is equipped with a Tire Pressure Monitor System (TPMS), it uses radio and sensor technology to check tire pressure levels in each of your installed tires. TPMS sensors monitor the air pressure in your vehicle's tires and transmit tire pressure readings to a receiver located in the vehicle. The TPMS is designed to alert the driver if a low tire pressure condition exists, and may also allow the driver to check tire pressure levels using the Driver Information Center (DIC) on your dashboard. If you have replaced your factory-installed tires or wheels, your TPM system may not be functioning properly. Check with your installer for compatibility.
Tire Pressure and Changing Temperatures — Tire pressure can change over time as temperature changes. The pressure goes up as temperature goes up, and pressure goes down as temperature goes down. (A good rule of thumb is that tire pressure changes 1 psi for a change of 10°F.) This can happen seasonally (from summer into fall), daily (from a cold night to a warmer afternoon), and while driving (the tires warm up as you drive).
You may notice during cooler weather conditions that the Low Tire Pressure indicator will appear when the vehicle is first started and then turn off as you start to drive. This is an early indicator that the pressure is getting low and tires need to be inflated to the proper pressure.
