Just saying that the OEM sensors do not have to be manually activated or the monitor system reset, as it resets itself in less than a few minutes. What you observed is consistent with either manual or automatic reset.
Yes, I believe that the numbers were changing since the pressure on the new tires were quite high. As I drove home.. it went up by another 1-2 psi.
To activate the sensors, the guy at discount tire had to use a device to scan for something. He said that that turns them on or maybe he was scanning to make sure the sensors are sending out signals and are readable.
Here is the pic of the wheels on the Jeep.
